@azchohfi, thank you for the contribution. This looks OK; after testing and getting more feedback from the team, I'll merge.

[azchohfi]

This is great! The reason for the failing TestFx.CI.Real is that the build machine is still on old build configurations. It needs VS2019, for net5, and this is still running on a VS2017 machine.

[Haplois]

The issue with the VS2019 machine when building it is that we get another error for UAP (Windows, 10.0, UAP, 10.0.10240.0, 10.0.14393.0). Any ideas on this?

The VM pool we're using does not have the required SDK installed. It's getting fixed.

[azchohfi]

Any updates on this?

[Haplois]

The infra team is still working on that. Hopefully, they'll push the new images this week, and we can merge this.

[azchohfi]

Build seems to be passing now.

[Haplois]

@azchohfi, the failing one is our internal pipeline that generates the signed builds. I'll check back with the infra team and try to resolve this asap.

[azchohfi]

I'll update this to use ProjectReunion 0.5.0-prerelease.

[Haplois]

Package generation failed, with the fixed pipeline as well. Could you check it?

~\scripts\build\TestFx.Loc.targets(73,5): error MSB3073: The command "xcopy /Y /I /S /E ..\..\..\packages\MSTest.Internal.TestFx.Localized.Documentation.1.0.0-build-20170420-1\contentFiles\any\any\Extensions\WinUI ..\..\..\artifacts\Release\Extension.WinUI\" exited with code 4. [~\src\TestFramework\Extension.WinUI\Extension.WinUI.csproj]

[azchohfi]

@Haplois The issue seems to be that MSTest.Internal.TestFx.Localized.Documentation, version 1.0.0-build-20170420-1 doesn't have any WinUI related xml files, which makes sense since this PR didn't update that package. Could you point me to where this should be updated?

[Haplois]

@azchohfi, there is a chicken and egg problem :) This repository generates that package; we need this merged to get those files. I'll fix that tomorrow and hopefully merge it.

[AbhitejJohn]

hmm, this would cause issues if the tests are run in parallel, wouldn't it?

[azchohfi]

I can't see why it could, given that you provide one. The same concept was/is used in UWP, and it works fine (UWP used a static property to get the CoreDispatcher). Preferably, this should be set only once, and only if needed.

[Haplois]

Added Microsoft.ProjectReunion package and its dependencies to dotnet-public field. It will be replicated from NuGet.org automatically.

[Haplois]

I fixed the issues with the build, we need to add some acceptance tests, but it looks ok.

[Scottj1s]

This is great, and much needed - thx!

[Haplois]

Thanks for the review @Scottj1s, and thank you for your contribution @azchohfi. It's merged.
