hmm. are the unused namespace removals indirect impact of bumping to rc1? assuming all the changes here are non-functional. I can't open them, too big :)

Yes, the result of dotnet/sdk#18459

@RussKie after this commit, build with VS2019 is not working (lots of errors). .\build.cmd seems to work.
Last working in VS commit is 54c7297

P.S.
Any side Net6 WinForms project also not build with this SDK 6.0.0-rc.1.21369.7 (with 6.0.0-preview.7.21370.10 too) with very strange erors:

What VS version? What .NET versions do you have installed?

[kirsan31]

hat VS version?

16.10.4. The only remaining after experiments with VS2022. P.s. I am still fixing the lost settings in stable 2019 after this...

What .NET versions do you have installed?

For now:

  2.1.816 [C:\Program Files\dotnet\sdk]
  5.0.202 [C:\Program Files\dotnet\sdk]
  5.0.204 [C:\Program Files\dotnet\sdk]
  5.0.302 [C:\Program Files\dotnet\sdk]
  6.0.100-preview.6.21355.2 [C:\Program Files\dotnet\sdk]

Was trying SDK 6.0.0-rc.1.21369.7 and 6.0.0-preview.7.21370.10.
I am understand that problems with c#10. Apparently 16.10 can't handle it even with <LangVersion>preview</LangVersion>.

Yes, you need to have .NET 6.0 P7+ (?) and the latest VS.

Yea thanks. I am done with experiments on VS2022 for a while. Perhaps I will try on 11.16p. when I clear up the consequences of 2022 installing...

Have you found any specific issues in VS 2022 that stop you from using it?

Have you found any specific issues in VS 2022 that stop you from using it?

Yes:

1. I was not able transfer my settings from VS2019. Export from VS2019 and Import to 2022 wasn't help and there were some errors during import.
2. Possibility to align minimized MDI child to default location (TOP LEFT) #5221 (comment). But I was not trying .Net5 projects.
3. I don't like New ikons and color scheme. I am using 2017 Blue scheme through extention (that need to be updated to 2022).
4. Other extensions that need to be updated.
