  },
  "Logging": {
    "IncludeScopes": false,
    "LogLevel": {
      "Default": "Warning"

3- in Asp.net Core Web Application in startup.cs add following codes:

3-1-

public void ConfigureServices(IServiceCollection services)
{
  // Add framework services.

  // Add This Line To access HttpContext from within the MsSqlLogger to get the user name, trace Identifier that gets error also for returning back logId inside httpContext.
  services.AddSingleton<IHttpContextAccessor, HttpContextAccessor>();
  services.AddMvc();
}

3-2-

public void Configure(IApplicationBuilder app, IHostingEnvironment env, ILoggerFactory loggerFactory,
            IHttpContextAccessor httpContextAccessor)
{
    loggerFactory.AddConsole(Configuration.GetSection("Logging"));
    loggerFactory.AddDebug();

    // Add This To Log to MsSql Db
    loggerFactory.AddMsSql(Configuration.GetConnectionString("LoggerConnection"), httpContextAccessor, "SampleApplication");

	// Also you can add as Provider as below:
	//loggerFactory.AddProvider(new MsSqlLoggerProvider((_, LogLevel) => LogLevel >= LogLevel.Trace,
        //     Configuration.GetConnectionString("LoggerConnection"), null,"SampleApplication"));            

    if (env.IsDevelopment())
    {
        app.UseDeveloperExceptionPage();
        app.UseBrowserLink();
    }
    else
    {
        app.UseExceptionHandler("/Home/Error");
    }

    app.UseStaticFiles();

    app.UseMvc(routes =>
    {
        routes.MapRoute(
            name: "default",
            template: "{controller=Home}/{action=Index}/{id?}");
    });
}

Using in Asp.net Core Web Application Targetting .NetFramework

To Use in Asp.Net Web Application targetting .NetFramework you should also add following nuget packages manually to your project.

• System.Security.Claims (4.3) from NUGET

• System.Diagnostics.StackTrace (4.3) from NUGET
