@Tratcher Do I need to have the latest preview version of Visual Studio in order to generate the reference assemblies?

Did the docs/ReferenceAssemblies.md instructions not work for you?

The good news is that this manual reference assembly generation process is going away soon. #23403

Did the docs/ReferenceAssemblies.md instructions not work for you?

No, it worked a few times in the past, but I usually end up doing them manually.

@Kahbazi where are you stuck with the ref assembly generation?

[Kahbazi]

I get error MSB4057: The target "GenerateReferenceSource" does not exist in the project. after running dotnet msbuild /t:GenerateReferenceSource.

If the changes in this PR is ok, I'll update the reference assemblies manually.

@Kahbazi let me try fetching your branch and see if I can get it to work or if I see the same issue. If I can get it to work maybe I can figure out the process for pushing a commit on top and we should be good. I'm not sure if I'll have to end-up creating a separate PR with your commit on it to be able to do it, but we can at least figure out the changes and you can apply them manually on top if necessary

Here is the patch with the changes, this should at least make it easier to make the changes. 0001-Update-ref-assemblies.txt

Alternatively, what I did was to run .\eng\scripts\GenerateReferenceAssemblies.ps1

[Kahbazi]

@javiercn thanks for the patch. I tried .\eng\scripts\GenerateReferenceAssemblies.ps1 before. It didn't work for me either.

[javiercn]

Merged.

@Kahbazi thanks for the contribution!
