Is it possible to support Fluent Assertions and xunit?

Do you mean if it's possible to use those within the Demystify.Everything projects? FluentAssertions for sure. XUnit is already used.

No, I mean when someone using FluentAssertions, xUnit or any other unit tests framework, make the output stack tracing info of exception Demystified.
I think unit test is a key use case that people will care about the Exception and stack trace info.

Just wanted to +1 this - Demystify makes async stack traces soooo much easier to read when diagnosing xUnit unit test failures.

I think this might be possible by creating a customised XunitTestInvoker (like this), and then using a TestFrameworkDiscovererAttribute to override the behaviour of [Fact] and [Theory] - there's an example doing that here (the purpose was fo DI, but the principal is the same).

@cocowalla Is upgrading to .NET Core 3.1 + an option? Because Ben Adams has fixed the async stack traces in .NET Core 3.1.

I'm on dotnet 6 now, but I think I was on dotnet 5 at the time of that comment - where Demystify was still an improvement over the standard async stack trace.
