DOTNET 6 Error - Cannot find compilation library location for package 'System.Security.Cryptography.Pkcs'

Describe the bug Existing tests fail after upgrade.

To Reproduce Upgrade Test Project from Dotnet 5 to Dotnet 6:

Expected behavior The template should transform

Information (please complete the following information):

• OS: Windows 11
• Dotnet6
• RazorLight version: – https://www.nuget.org/packages/RazorLight/2.0.0-rc.3 – https://www.nuget.org/packages/RazorLight.NetCore3/
• Are you using the OFFICIAL RazorLight package? https://www.nuget.org/packages/razorlight
• Visual Studio version : Visual Studio Community 2022 Professional Released

Additional context TEST

    public void Convert_GivenValidInput_ShouldConvert()
    {
      // arrange
      Setup();
      var data = new { Name = "TheName" };
      var template = "Name is @Model.Name";

      // action
      var result = _engine.Convert(data, template, true);

      // assert
      result .Should().Be("Name is TheName");
  }

IMPLEMETATION:

        var result = engine.CompileRenderStringAsync(GetTemplateCachedId(templateData), templateData, data,  (ExpandoObject)null).Result;

@leighmetzroth @jacodv We did it! https://www.nuget.org/packages/RazorLight/2.0.0-rc.6

So for people still having the issue the ultimate solution for this is setting PreserveCompilationContext to true and adding ExcludingAssembly like:

            services.AddRazorLight(() =>
            {
                return new RazorLightEngineBuilder()
                    .UseFileSystemProject(Path.GetDirectoryName(Assembly.GetExecutingAssembly().Location))
                    .UseMemoryCachingProvider()
                    .ExcludeAssemblies(typeof(System.Security.Cryptography.Pkcs.AlgorithmIdentifier).Assembly.GetName().Name) // Workaround for loading CompileLibraries
                    .EnableDebugMode(Debugger.IsAttached)
                    .Build();
            });

If you will try to Exclude Assembly with FullName It will not work. Additonally the RazorLightDependancyEngineBuilder is broken and all ExcludedAssemblies are ignored further in DefaultMetadataReferenceManager. @jzabroski
