Arcade SDK is a set of msbuild props and targets files and packages that provide common build features used across multiple repos, such as CI integration, packaging, VSIX and VS setup authoring, testing, and signing via Microbuild.
The infrastructure of most repositories that contribute to the .NET stack is built on top of Arcade SDK. This allows us to orchestrate the build of the entire stack as well as build the stack from source. These repositories are expected to be on the latest version of the Arcade SDK.
Repositories that do not contribute to the .NET stack may also use Arcade SDK in order to take advantage of the common infrastructure.
The goals are
- to reduce the number of copies of the same or similar props, targets and script files across repos
- enable cross-platform build that relies on a standalone dotnet cli (downloaded during restore) as well as desktop msbuild based build
- be as close to the latest shipping .NET Core SDK as possible, with minimal overrides and tweaks
- be modular and flexible, not all repos need all features; let the repo choose subset of features to import
- unify common operations and structure across repos
- unify Azure DevOps Build Pipelines used to produce official builds
The toolset has four kinds of features and helpers:
- Common conventions applicable to all repos using the toolset.
- Infrastructure required for Azure DevOps CI builds, MicroBuild and build from source.
- Workarounds for bugs in shipping tools (dotnet SDK, VS SDK, msbuild, VS, NuGet client, etc.). Will be removed once the bugs are fixed in the product and the toolset moves to the new version of the tool.
- Abstraction of peculiarities of VSSDK and VS insertion process that are not compatible with dotnet SDK.
The toolset has following requirements on the repository layout.
All build outputs are located under a single directory called artifacts
.
The Arcade SDK defines the following output structure:
artifacts
bin
$(MSBuildProjectName)
$(Configuration)
packages
$(Configuration)
Shipping
$(MSBuildProjectName).$(PackageVersion).nupkg
NonShipping
$(MSBuildProjectName).$(PackageVersion).nupkg
Release
PreRelease
TestResults
$(Configuration)
$(MSBuildProjectName)_$(TargetFramework)_$(TestArchitecture).(xml|html|log|error.log)
VSSetup
$(Configuration)

$(VsixPackageId).json
$(VsixPackageId).vsmand
$(VsixContainerName).vsix
$(VisualStudioInsertionComponent).vsman
DevDivPackages

$(VisualStudioInsertionComponent)
SymStore
$(Configuration)
$(MSBuildProjectName)
log
$(Configuration)
Build.binlog
tmp
$(Configuration)
obj
$(MSBuildProjectName)
$(Configuration)
toolset
Having a common output directory structure makes it possible to unify MicroBuild definitions.
directory | description |
---|---|
bin | Build output of each project. |
obj | Intermediate directory for each project. |
packages | NuGet packages produced by all projects in the repo. |
VSSetup | Packages produced by VSIX projects in the repo. These packages are experimental and can be used for dogfooding. |
VSSetup/Insertion | Willow manifests and VSIXes to be inserted into VS. |
VSSetup.obj | Temp files produced by VSIX build. |
SymStore | Storage for converted Windows PDBs |
log | Build binary log and other logs. |
tmp | Temp files generated during build. |
toolset | Files generated during toolset restore. |
Arcade provides common build scripts in the eng/common folder:
-
The scripts are designed to be used by repos that need a single
MSBuild
invocation to restore, build, package and test all projects in the repo. These scripts are thin wrappers calling into functions defined ineng/common/tools.ps1|sh
. If the repository needs to run additional builds or commands it is recommended to createeng/build.ps1|sh
scripts in the repository usingeng/common/build.ps1|sh
as a template and customize the implementation as necessary. These custom scripts should use common helpers and global variables defined ineng/common/tools.ps1|sh
and provide command line switches that are a superset of the ones provided byeng/common/build.ps1|sh
. -
Defines global variables and functions used in all builds scripts. This includes helpers that install .NET SDK, invoke MSBuild, locate Visual Studio, report build telemetry, etc.
-
eng/common/CIBuild.cmd|cibuild.sh
Repositories that use
eng/common/build.ps1|sh
(as opposed to a customizedeng/build.ps1|sh
) should use this build script for the main build step in their pipeline definition. Repositories with customeng/build.ps1|sh
should also add the correspondingeng/CIBuild.cmd|cibuild.sh
for use in their pipeline definition.
Since YAML pipeline definition is only executable in CI and not locally on a dev machine the repositories shall minimize the logic implemented in their pipeline definition. Instead of adding more build steps to the pipeline definition that follow
eng/common/CIBuild.cmd
repositories should opt for using the customized build scripts (eng/build.ps1|sh
) and add the logic there.
Repos may also provide a few convenience build scripts in the repository root that dispatch to either eng/common/build.ps1|sh
or eng/build.ps1|sh
(if repo uses customized build scripts) but do not implement any logic:
- Build.cmd | build.sh - default wrapper script for building and restoring the repo.
- Restore.cmd | restore.sh - default wrapper script for restoring the repo.
- Test.cmd | test.sh - default wrapper script for running tests in the repo.
Since the default scripts pass along additional arguments, you could restore, build, and test a repo by running Build.cmd -test
.
You should feel free to create more repo specific scripts as appropriate to meet common dev scenarios for your repo.
The Arcade SDK requires bootstrapper scripts to be present in the repo.
The scripts in this directory shall be present and the same across all repositories using Arcade SDK.
Provide repo specific Build properties such as the list of projects to build.
By default, Arcade builds solutions in the root of the repo. Overriding the default build behavior may be done by either of these methods.
-
Provide the project list on the command-line. This will override any list of projects set in
eng/Build.props
.Example:
build.cmd -projects MyProject.proj
See source code
-
Provide a list of projects or solutions in
eng/Build.props
.Example:
<Project ToolsVersion="4.0" xmlns="http://schemas.microsoft.com/developer/msbuild/2003"> <ItemGroup> <ProjectToBuild Include="$(MSBuildThisFileDirectory)..\MyProject.proj" /> </ItemGroup> </Project>
Note: listing both project files formats (such as .csproj) and solution files (.sln) at the same time is not currently supported.
This is often required for repos which have multiple .sln files in the root directory.
<!-- eng/Build.props -->
<Project>
<ItemGroup>
<ProjectToBuild Include="$(RepoRoot)MySolution1.sln" />
</ItemGroup>
</Project>
You can also specify a list of projects to build instead of building .sln files.
<!-- eng/Build.props -->
<Project>
<ItemGroup>
<ProjectToBuild Include="$(RepoRoot)src\**\*.csproj" />
</ItemGroup>
</Project>
You can use custom MSBuild properties to control the list of projects which build.
<!-- eng/Build.props -->
<Project>
<ItemGroup>
<!-- Usage: build.cmd /p:BuildMyOptionalGroupOfStuff=true -->
<ProjectToBuild Condition="'$(BuildMyOptionalGroupOfStuff)' == 'true"
Include="$(RepoRoot)src\feature1\**\*.csproj" />
<!-- Only build some projects when building on Windows -->
<ProjectToBuild Condition="'$(OS)' == 'Windows_NT"
Include="$(RepoRoot)src\**\*.vcxproj" />
<!-- You can also use MSBuild Include/Exclude syntax -->
<ProjectToBuild Include="$(RepoRoot)src\**\*.csproj"
Exclude="$(RepoRoot)src\samples\**\*.csproj" />
</ItemGroup>
</Project>
By default, Arcade assumes that the 'Restore' target on projects is implemented using NuGet's restore. If that is not the case, you can opt-out of some Arcade optimizations by setting 'RestoreUsingNuGetTargets' to false.
<!-- eng/Build.props -->
<Project>
<PropertyGroup>
<RestoreUsingNuGetTargets>false</RestoreUsingNuGetTargets>
</PropertyGroup>
<ItemGroup>
<ProjectToBuild Include="$(RepoRoot)src\dir.proj" />
</ItemGroup>
</Project>
CoreFx does not use the default build projects in its repo - example.
The file is present in the repo and defines versions of all dependencies used in the repository, the NuGet feeds they should be restored from and the version of the components produced by the repo build.
<Project>
<PropertyGroup>
<!-- Base three-part version used for all outputs of the repo (assemblies, packages, vsixes) -->
<VersionPrefix>1.0.0</VersionPrefix>
<!-- Package pre-release label not including build number or the pre-release iteration-->
<PreReleaseVersionLabel>rc</PreReleaseVersionLabel>
<!-- Package pre-release version iteration. Combines with the label to produce a final pre-release suffix. -->
<PreReleaseVersionIteration>2</PreReleaseVersionIteration>
<!-- Optional: base short date used for calculating version numbers of release-only packages (e.g. global tools) -->
<VersionBaseShortDate>19000</VersionBaseShortDate>
<!-- Opt-in repo features -->
<UsingToolVSSDK>true</UsingToolVSSDK>
<UsingToolIbcOptimization>true</UsingToolIbcOptimization>
<!-- Opt-out repo features -->
<UsingToolXliff>false</UsingToolXliff>
<!-- Versions of other dependencies -->
<MyPackageVersion>1.2.3-beta</MyPackageVersion>
</PropertyGroup>
</Project>
The toolset defines a set of tools (or features) that each repo can opt into or opt out. Since different repos have different needs the set of tools that will be imported from the toolset can be controlled by UsingTool{tool-name}
properties, where tool-name is e.g. Xliff
, SourceLink
, XUnit
, VSSDK
, IbcOptimization
, etc. These properties shall be set in the Versions.props file.
The toolset also defines default versions for various tools and dependencies, such as MicroBuild, XUnit, VSSDK, etc. These defaults can be overridden in the Versions.props file.
See DefaultVersions for a list of UsingTool properties and default versions.
Specify package references to additional tools that are needed for the build. These tools are only used for build operations performed outside of the repository solution (such as additional packaging, signing, publishing, etc.).
Customization of Authenticode signing process.
Configurable item groups:
ItemsToSign
List of files to sign in-place, during the build. May list individual files to sign (e.g. .dll, .exe, .ps1, etc.) as well as container files (.nupkg, .vsix, .zip, etc.). All files embedded in a container file are signed (recursively) unless specified otherwise.ItemsToSignPostBuild
List of file names (without paths) to sign in post build release pipeline. May only contain files that are published. All files embedded in a container file are signed (recursively) unless specified otherwise.FileSignInfo
Specifies Authenticode certificate to use to sign files with given file name.FileExtensionSignInfo
Specifies Authenticode certificate to use to sign files with given extension.CertificatesSignInfo
Specifies Authenticode certificate properties, such as whether a certificate allows dual signing.StrongNameSignInfo
Strong Name key to use to sign a specific managed assembly.
Properties:
AllowEmptySignList
True to allow ItemsToSign to be empty (the repository doesn't have any file to sign in-build).AllowEmptyPostBuildSignList
True to allow ItemsToSignPostBuild to be empty (the repository doesn't have any file to sign post-build).PostBuildSign
If trueItemsToSignPostBuild
is tracked during the publishing process and these files will be signed during post-build.ItemsToSignPostBuild
is populated with the default arcadeItemsToSign
.
See Signing.md for details.
To change the key used for strong-naming assemblies see StrongNameKeyId
property.
Customization of publishing process.
Targets executed in a step right after the solution is built.
Targets executed in a step right after artifacts has been signed.
/global.json
file is present and specifies the version of the dotnet and Microsoft.DotNet.Arcade.Sdk
SDKs.
For example,
{
"tools": {
"dotnet": "2.1.400-preview-009088"
},
"msbuild-sdks": {
"Microsoft.DotNet.Arcade.Sdk": "1.0.0-prerelease-63208-02"
}
}
Include vs
entry under tools
if the repository should be built via msbuild
from Visual Studio installation instead of dotnet cli:
{
"tools": {
"vs": {
"version": "15.9"
}
}
}
Optionally, a list of Visual Studio workload component ids may be specified under vs
:
"vs": {
"version": "15.9",
"components": ["Microsoft.VisualStudio.Component.VSSDK"]
}
If the build runs on a Windows machine that does not have the required Visual Studio version installed the build.ps1
script attempts to use xcopy-deployable MSBuild package RoslynTools.MSBuild
. This package will allow the build to run on desktop msbuild but it may not provide all tools that the repository needs to build all projects and/or run all tests.
The version of RoslynTools.MSBuild
package can be specified in global.json
file under tools
like so:
{
"tools": {
"vs": {
"version": "16.0"
},
"xcopy-msbuild": "16.0.0-rc1-alpha"
}
}
If it is not specified the build script attempts to find RoslynTools.MSBuild
version {VSMajor}.{VSMinor}.0-alpha
where VSMajor.VSMinor
is the value of tools.vs.version
.
If the fallback behavior to use xcopy-deployable MSBuild package is not desirable, then a version of none
should be indicated in global.json
, like this:
{
"tools": {
"vs": {
"version": "16.4"
},
"xcopy-msbuild": "none"
}
}
In /global.json, specify a runtimes
section and list the shared runtime versions you want installed.
Schema:
{
"tools": {
"dotnet": "<version>", // define CLI SDK version
"runtimes": { // optional runtimes section
"<runtime>": [ "<version>", ..., "<version>" ],
...,
"<runtime>/<architecture>": [ "<version>", ..., "<version>" ]
}
}
}
<runtime>
- One of the supported "runtime" values for the dotnet-install script.
<architecture>
- Optionally include /<architecture>
when defining the runtime to specify an explicit architecture where "architecture" is one of the supported values for the dotnet-install script. Defaults to "auto" if not specified.
{
"tools": {
"dotnet": "3.0.100-preview3-010431",
"runtimes": {
"dotnet/x64": [ "2.1.7" ],
"aspnetcore/x64": [ "3.0.0-build-20190219.1" ]
}
}
}
You may also use any of the properties defined in eng/Versions.props
to define a version.
Example
{
"tools": {
"dotnet": "3.0.100-preview3-010431",
"runtimes": {
"dotnet/x64": [ "2.1.7", "$(MicrosoftNetCoreAppVersion)" ]
}
}
}
Note: defining runtimes
in your global.json will signal to Arcade to install a local version of the SDK for the runtimes to use rather than depending on a matching global SDK.
/NuGet.config
file is present and specifies the MyGet feed to retrieve Arcade SDK from and other feeds required by the repository like so:
<?xml version="1.0" encoding="utf-8"?>
<configuration>
<packageSources>
<clear />
<!-- Feed to use to restore the Arcade SDK from -->
<add key="dotnet-eng" value="https://pkgs.dev.azure.com/dnceng/public/_packaging/dotnet-eng/nuget/v3/index.json" />
<!-- Feeds to use to restore dependent packages from -->
<add key="my-feed" value="https://dotnet.myget.org/F/myfeed/api/v3/index.json" />
</packageSources>
<disabledPackageSources>
<clear />
</disabledPackageSources>
</configuration>
Directory.Build.props
shall import Arcade SDK as shown below. The Sdk.props
file sets various properties and item groups to default values. It is recommended to perform any customizations after importing the SDK.
It is a common practice to specify properties applicable to all (most) projects in the repository in Directory.Build.props
, e.g. public keys for InternalsVisibleTo
project items.
<Project>
<Import Project="Sdk.props" Sdk="Microsoft.DotNet.Arcade.Sdk" />
<PropertyGroup>
<!-- Public keys used by InternalsVisibleTo project items -->
<MoqPublicKey>00240000048000009400...</MoqPublicKey>
<!--
Specify license used for packages produced by the repository.
Use PackageLicenseExpressionInternal for closed-source licenses.
-->
<PackageLicenseExpression>MIT</PackageLicenseExpression>
<!--
Specify an id of the key used to generate strong names of assemblies built from this repo.
-->
<StrongNameKeyId>Microsoft</StrongNameKeyId>
</PropertyGroup>
</Project>
Directory.Build.targets
shall import Arcade SDK. It may specify additional targets applicable to all source projects.
<Project>
<Import Project="Sdk.targets" Sdk="Microsoft.DotNet.Arcade.Sdk" />
</Project>
The root of the repository shall include a license file named license.txt
, license.md
or license
(any casing is allowed).
It is expected that all packages built from the repository have the same license, which is the license declared in the repository root license file.
If the repository uses open source license it shall specify the license name globally using PackageLicenseExpression
property, e.g. in Directory.Build.props.
If the repository uses a closed source license it shall specify the license name using PackageLicenseExpressionInternal
property. In this case the closed source license file is automatically added to any package build by the repository.
If PackageLicenseExpression(Internal)
property is set Arcade SDK validates that the content of the license file in the repository root matches the content of
the well-known license file that corresponds to the value of the license expression.
This validation can be suppressed by setting SuppressLicenseValidation
to true
if necessary (not recommended).
See NuGet documentation for details.
Projects are located under src
directory under root repo, in any subdirectory structure appropriate for the repo.
Projects shall use Microsoft.NET.Sdk
SDK like so:
<Project Sdk="Microsoft.NET.Sdk">
...
</Project>
- Unit test project file names shall end with
.UnitTests
or.Tests
, e.g.MyProject.UnitTests.csproj
orMyProject.Tests.csproj
. - Integration test project file names shall end with
.IntegrationTests
, e.g.MyProject.IntegrationTests.vbproj
. - Performance test project file names shall end with
.PerformanceTests
, e.g.MyProject.PerformanceTests.csproj
. - If
source.extension.vsixmanifest
is present next to the project file the project is by default considered to be a VSIX producing project.
It might be useful to create other top-level directories containing projects that are not standard C#/VB/F# projects. For example, projects that aggregate outputs of multiple projects into a single NuGet package or Willow component. These projects should also be included in the main solution so that the build driver includes them in build process, but their Directory.Build.*
may be different from source projects. Hence the different root directory.
Arcade SDK provides targets for building source packages.
Set IsSourcePackage
to true
to indicate that the project produces a source package (along with IsPackable
, PackageDescription
and other package properties).
If the project does not have an explicitly provided .nuspec
file (NuspecFile
property is empty) setting IsSourcePackage
to true
will trigger a target that
puts sources contained in the project directory to the contentFiles
directory of the source package produced by the project.
In addition a build/$(PackageId).targets
file will be auto-generated that links the sources contained in the package to the source server via a Source Link target.
If your package already has a build/$(PackageId).targets
file set SourcePackageSourceLinkTargetsFileName
property to a different file name (e.g. SourceLink.targets
)
and import the file from build/$(PackageId).targets
.
If the project is packaged using a custom .nuspec
file then the source and targets files must be listed in the .nuspec
file. The path to the generated Source Link
targets file will be available within the .nuspec
file via variable $SourceLinkTargetsFilePath$
.
Building Visual Studio components is an opt-in feature of the Arcade SDK. Property UsingToolVSSDK
needs to be set to true
in the Versions.props
file. You need to build using framework MSBuild when building VSIX packages. To build using framework MSBuild, specify the MSBuild engine as VS when building.
Set VSSDKTargetPlatformRegRootSuffix
property to specify the root suffix of the VS hive to deploy to.
If source.extension.vsixmanifest
is present next to a project file the project is by default considered to be a VSIX producing project (IsVsixProject
property is set to true).
A package reference to Microsoft.VSSDK.BuildTools
is automatically added to such project.
Arcade SDK include build target for generating VS Template VSIXes. Adding VSTemplate
items to project will trigger the target.
source.extension.vsixmanifest
shall specify Experimental="true"
attribute in Installation
section. The experimental flag will be stripped from VSIXes inserted into Visual Studio.
VSIX packages are built to VSSetup
directory.
Repository that builds VS insertion components must set VisualStudioDropName
global property (see Common steps in Azure DevOps pipeline)
To include the output VSIX of a project in Visual Studio insertion, set the VisualStudioInsertionComponent
property.
Multiple VSIXes can specify the same component name, in which case their manifests will be merged into a single insertion unit.
The Visual Studio insertion manifests and VSIXes are generated during Pack task into VSSetup\Insertion
directory, where they are picked up by MicroBuild Azure DevOps publishing task during official builds.
Arcade SDK also enables building VS Setup Components from .swr files (as opposed to components comprised of one or more VSIXes).
Projects that set VisualStudioInsertionComponent
but do not have source.extension.vsixmanifest
are considered to be swix projects (IsSwixProject
property is set to true).
Use SwrProperty
and SwrFile
items to define a property that will be substituted in .swr files for given value and the set of .swr files, respectively.
For example,
<Project Sdk="Microsoft.NET.Sdk">
<PropertyGroup>
<TargetFramework>net46</TargetFramework>
<VisualStudioInsertionComponent>Microsoft.VisualStudio.ProjectSystem.Managed</VisualStudioInsertionComponent>
</PropertyGroup>
<ItemGroup>
<SwrProperty Include="Version=$(VsixVersion)" />
<SwrProperty Include="VisualStudioXamlRulesDir=$(VisualStudioXamlRulesDir)" />
</ItemGroup>
<ItemGroup>
<SwrFile Include="*.swr" />
</ItemGroup>
</Project>
Where .swr file is:
use vs
package name=Microsoft.VisualStudio.ProjectSystem.Managed.CommonFiles
version=$(Version)
vs.localizedResources
vs.localizedResource language=en-us
title="Microsoft VisualStudio Managed Project System Common Files"
description="Microsoft VisualStudio ProjectSystem for C#/VB/F#(Managed) Projects"

file source="$(VisualStudioXamlRulesDir)Microsoft.VisualBasic.DesignTime.targets"
file source="$(VisualStudioXamlRulesDir)Microsoft.FSharp.DesignTime.targets"
file source="$(VisualStudioXamlRulesDir)Microsoft.Managed.DesignTime.targets"
NOTE: By defining VisualStudioInsertionComponent
in your project you are implicitly opting-in to having all of the assemblies included in that package marked for NGEN
. If this is not something you want for a given component you may add <Ngen>false</Ngen>
.
example:
<Project Sdk="Microsoft.NET.Sdk">
<PropertyGroup>
<TargetFramework>net472</TargetFramework>
<VisualStudioInsertionComponent>MyVisualStudioInsertionComponent</VisualStudioInsertionComponent>
<Ngen>false</Ngen>
</PropertyGroup>
</Project>

The Arcade SDK includes targets that enable IBC optimization data to be embedded to assemblies produced by the repository.
To enable this functionality set UsingToolIbcOptimization
to true
in /eng/Versions.props
.
Typically, not all projects in a repository need IBC data embedded. Set ApplyNgenOptimization
to partial
or full
in a project to indicate that the assemblies produced by the project should get IBC data embedded.
Use EnableNgenOptimization
property to control when IBC data embedding is gonna be performed.
Unless specified otherwise, EnableNgenOptimization
is set to true
if Configuration
is Release
and OfficialBuild
is true
.
The IBC data embedding is performed by an internal tool ibcmerge.exe
provided by Microsoft.Dotnet.IbcMerge
package from an internal Azure DevOps feed. The repository build definition thus must invoke Azure DevOps task
that restores internal tools in order for IBC data embedding to work. See Restoring internal tools.
Unless the repository is using an IBC data acquisition mechanism built into the Arcade SDK (such as
Visual Studio IBC Data Acquisition) the repository must set the value of
IbcOptimizationDataDir
property and its build must ensure that IBC data are present at the location specified
by this property before the Build
target is executed. It is recommended that such logic is implemented in
/eng/Tools.props
via a target chained after the Restore
target.
IbcOptimizationDataDir
specifies the directory that contains optimization data (must end with a directory separator).
The optimization data directory is expected to have the following structure:
$(IbcOptimizationDataDir)path1\{AssemblyFileName1}\{AssemblyFileName1}
$(IbcOptimizationDataDir)path1\{AssemblyFileName1}\Scenario1.ibc
$(IbcOptimizationDataDir)path1\{AssemblyFileName1}\Scenario2.ibc
$(IbcOptimizationDataDir)path2\{AssemblyFileName2}\{AssemblyFileName2}
$(IbcOptimizationDataDir)path2\{AssemblyFileName2}\Scenario1.ibc
$(IbcOptimizationDataDir)path2\{AssemblyFileName2}\Scenario2.ibc
...
The assemblies must be exactly those that were used in the training run that produced the IBC data files.
One assembly might be present in multiple copies in different subdirectories. These copies must be identical
(an assembly is identified by name only). ApplyOptimizations
target aggregates all IBC data files present
next to the assembly and all of its copies. Multiple flavors of an assembly with the same names
(e.g. assemblies produced by a multi-targeted project) are currently not supported. If necessary in future,
it is possible to update the target to group assemblies by MVID instead of file name.
During the build IBC data embedding is performed by ApplyOptimizations
target, which invokes ibcmerge.exe
tool.
The target runs when EnableNgenOptimization
is true
and the project sets ApplyNgenOptimization
to partial
or full
. The target consumes item group OptimizeAssembly
, whose items are full paths to the assemblies to have
IBC data embedded. The assemblies are updated in-place. By default, OptimizeAssembly
is initialized with
the path of the intermediate assembly compiled by the project (this is the file the CoreCompile
target builds
to obj
directory). The project may update OptimizeAssembly
item group before ApplyOptimizations
target is
executed if it needs to embed IBC data to other assemblies.
Visual Studio Engineering provides an Azure DevOps Release Pipeline that performs IBC training for assemblies shipped with Visual Studio. Arcade SDK enables repositories to retrieve and embed IBC data this system produces as well as generate inputs for the training.
To enable this functionality set UsingToolVisualStudioIbcTraining
to true
in /eng/Versions.props
.
Set EnableNgenOptimization
property globally or in /eng/Tools.props
to control when IBC data should be acquired.
The IBC data acquisition is performed by an internal tool drop.exe
provided by Drop.App
package from an internal Azure
DevOps feed. The repository build definition thus must invoke Azure DevOps task that restores internal tools in order for
IBC data embedding to work. See Restoring internal tools.
To retrieve the data the tool needs to authenticate to the VS drop storage. The access token necessary for the authentication
is passed via VisualStudioDropAccessToken
property. If the account the official build of the repository is running on has
an access to the VS drop storage, the build definition can pass /p:VisualStudioDropAccessToken=$(System.AccessToken)
to
the /eng/common/CIBuild.cmd
script.
The IBC data drop produced by a training run is identified by the name of the repository, the branch and the build number
the trained binaries came from, and a training run id. An example of IBC data identifier is
OptimizationData/dotnet/roslyn/master-vs-deps/20190210.1/935479/1
, where dotnet/roslyn
is the repository name,
master-vs-deps
is the branch name, 20190210.1
is the build number and 935479/1
is training run id.
The IBC data acquisition implementation in Arcade SDK requires RepositoryName
and VisualStudioIbcSourceBranchName
properties to be set globally or in /eng/Tools.props
file. These properties specify the repository name and
the branch name to use to find the IBC data to acquire. Set VisualStudioIbcDropId
to the combination of build number
and training run id (e.g. 20190210.1/935479/1
) to indicate the exact IBC data drop to acquire. If VisualStudioIbcDropId
is not specified the most recent IBC data published from the specified repository and branch are acquired.
The IBC data are downloaded to IbcOptimizationDataDir
, which is initialized to .tools/IbcData
.
The training process requires:
- List of scenarios (tests) to run and binaries to train in each scenario
- VS Bootstrapper that installs a specific build of Visual Studio and the VS insertion components built by the repository official build
- Test settings (
Training.runsettings
file)
The scenarios are expected to be listed in file /eng/config/OptProf.json
in the repository. Arcade SDK reads this file and
generates corresponding input files to the training process.
The VS Bootstrapper is built by an Azure DevOps task provided by MicroBuild.
The Training.runsettings
file is generated by Arcade SDK task VisualStudio.BuildIbcTrainingSettings
.
The following build definition steps are required for successful generation of all training inputs (in the listed order):
variables:
VisualStudio.MajorVersion: 16 # specify applicable value
VisualStudio.ChannelName: 'int.d16.0stg' # specify applicable value
VisualStudio.IbcSourceBranchName: 'master-vs-deps' # specify applicable value

To test IBC data embedding and IBC training inputs generation locally:
- Restore internal tools:
nuget.exe restore eng\common\internal\Tools.csproj
NuGet.exe may ask for credentials. Note: You need a credential provider for NuGet to be able to successfully authenticate.
- Run build with the following arguments (choose values of
RepositoryName
andVisualStudioIbcSourceBranchName
as appropriate):
build -configuration Release -restore -ci /p:EnableNgenOptimization=true /p:RepositoryName=dotnet/roslyn /p:VisualStudioIbcSourceBranchName=dev16.0-vs-deps
true
if Version
needs to respect SemVer 1.0. Default is false
, which means format following SemVer 2.0.
The id of the key used to generate assembly strong name for signed assemblies (SignAssembly
is true
).
By default, SignAssembly
is set to true
and StrongNameKeyId
is set to MicrosoftShared
.
Available values are listed in StrongName.targets.
AssemblyOriginatorKeyFile
, PublicKey
, PublicKeyToken
, DelaySign
, PublicSign
properties are set based on the value of StrongNameKeyId
.
IsShipping-
properties are project properties that determine which (if any) assets produced by the project are shipping. An asset is considered shipping if it is intended to be delivered to customers via an official channel. This channel can be NuGet.org, an official installer, etc. Setting this flag to true
does not guarantee that the asset will actually ship in the next release of the product. It might be decided after the build is complete that although the artifact is ready for shipping it won't be shipped this release cycle.
By default all assets produced by a project are considered shipping. Set IsShipping
to false
if none of the assets produced by the project are shipping. Test projects (IsTestProject
is true
) set IsShipping
to false
automatically.
Setting IsShipping
property is sufficient for most projects. Projects that produce both shipping and non-shipping assets need a finer grained control. Set IsShippingAssembly
, IsShippingPackage
or IsShippingVsix
to false
if the assembly, package, or VSIX produced by the project is not shipping, respectively.
Build targets shall not directly use IsShipping
. Instead they shall use IsShippingAssembly
, IsShippingPackage
and IsShippingVsix
depending on the asset they are dealing with.
Examples of usage:
-
Set
IsShipping
property tofalse
in test/build/automation utility projects. -
Set
IsShipping
property tofalse
in projects that produce VSIX packages that are only used only within the repository (e.g. to facilitate integration tests or VS F5) and not expected to be installed by customers. -
Set
IsShippingPackage
property tofalse
in projects that package shipping assemblies in packages that facilitate transport of assets from one repository to another one, which extracts the assemblies and ships them in a shipping container.
All assemblies, packages and VSIXes are signed by default, regardless of whether they are shipping or not.
By default, Portable and Embedded PDBs produced by shipping projects are converted to Windows PDBs and published to Microsoft symbol servers.
By default, all shipping libraries are localized.
When UsingToolNuGetRepack
is true shipping packages are repackaged as release/pre-release packages to artifacts\packages\$(Configuration)\Release
and artifacts\packages\$(Configuration)\PreRelease
directories, respectively.
Set to true
in projects that build Visual Studio Build (CoreXT) packages. These packages are non-shipping, but their content is shipping. They are inserted into and referenced from the internal DevDiv VS
repository.
true
(default) if the PDBs produced by the project should be converted to Windows PDB and published to Microsoft symbol servers.
Set to false
to override the default (uncommon).
Set to partial
or full
in a shipping project to require IBC optimization data to be available for the project and embed them into the binary during official build. The value of partial
indicates partial NGEN, whereas full
means full NGEN optimization.
Properties that define TargetFramework for use by projects so their targeting easily aligns with the current .NET version in development as well as those that are supported. Arcade will update these properties to match the current supported .NET versions, as well as the release being currently developed.
- NetCurrent - The TFM of the major release of .NET that the Arcade SDK aligns with.
- NetPrevious - The previously released version of .NET (e.g. this would be net7 if NetCurrent is net8)
- NetMinimum - Lowest supported version of .NET the time of the release of NetCurrent. E.g. if NetCurrent is net8, then NetMinimum is net6
- NetFrameworkMinimum - Lowest supported version of .NET Framework the time of the release of NetCurrent. E.g. if NetCurrent is net8, then NetFrameworkMinimum is net462
Set to true
in a test project to skip running tests.
List of test architectures (x64
, x86
) to run tests on.
If not specified by the project defaults to the value of PlatformTarget
property, or x64
if Platform
is AnyCPU
or unspecified.
For example, a project that targets AnyCPU
can opt-into running tests using both 32-bit and 64-bit test runners on .NET Framework by setting TestArchitectures
to x64;x86
.
An alternative path where to save test standard output logs (e.g., MyProject.Tests_tfm_arch.log
). If not specified, these logs will be saved under the path specified in $(ArtifactsLogDir)
variable.
By default, the test runner will run tests for all frameworks a test project targets. Use TestTargetFrameworks
to reduce the set of frameworks to run against.
For example, consider a project that has <TargetFrameworks>netcoreapp3.1;net472</TargetFrameworks>
. To only run .NET Core tests run
msbuild Project.UnitTests.csproj /t:Test /p:TestTargetFrameworks=netcoreapp3.1
To specify multiple target frameworks on command line quote the property value like so:
msbuild Project.UnitTests.csproj /t:Test /p:TestTargetFrameworks="netcoreapp3.1;net472"
Runtime to use for running tests. Currently supported values are: Core
(.NET Core), Full
(.NET Framework) and Mono
(Mono runtime).
For example, the following runs .NET Framework tests using Mono runtime:
msbuild Project.UnitTests.csproj /t:Test /p:TestTargetFrameworks=net472 /p:TestRuntime=Mono
Additional command line arguments passed to the test runner (e.g. xunit.console.exe
).
Additional command line arguments passed to the test runtime (i.e. dotnet
or mono
). Applicable only when TestRuntime
is Core
or Mono
.
For example, to invoke Mono with debug flags --debug
(to get stack traces with line number information), set TestRuntimeAdditionalArguments
to --debug
.
To override the default Shared Framework version that is selected based on the test project TFM, set TestRuntimeAdditionalArguments
to --fx-version x.y.z
.
Timeout to apply to an individual invocation of the test runner (e.g. xunit.console.exe
) for a single configuration. Integer number of milliseconds.
When set to true
, Arcade will generate a class source for all embedded .resx files.
If source should only be generated for some .resx files, this can be turned on for individual files like this:
<ItemGroup>
<EmbeddedResource Update="MyResources.resx" GenerateSource="true" />
</ItemGroup>
The contents of the generated source can be fine-tuned with these additional settings.
When a string in the resx file has argument placeholders, generate a .FormatXYZ(...)
method with parameters for each placeholder in the string.
Example: if the resx file contains a string "This has {0} and {1} placeholders", this method will be generated:
class Resources
{
// ...
public static string FormatMyString(object p0, object p1) { /* ..uses string.Format()... */ }
}
If set to true
calls to GetResourceString receive a default resource string value.
If set to true
the GetResourceString method is not included in the generated class and must be specified in a separate source file.
If set to true
the FlagNetStandard1xDependencies
target validates that the dependency graph doesn't contain any netstandard1.x packages.
If this environment variable is set, the value will be used to override the default Build Tools Framework version.
