Project load failure - Failed to find all versions of .NET Core MSBuild. Call to hostfxr_resolve_sdk2

[winzig]

Type: Bug

Issue Description

(Running on macOS Silicon)

Just recently have suddenly been having problems with definition not found when trying to do code navigation, e.g. right-click on a class name and "Go to Definition." Never had this problem before, but no matter how many restarts, reinstalls of the C# extension, etc., can't seem to get it working again.

Steps to Reproduce

I open up my usual C# project, build it (no errors), and then try to do things like "Go to Definition" on a class name or the like, and I get the "No definition found for..." error.

Also, I downgraded to 2.0.436 and the issues have gone away, so it's something new. I also tried the pre-release, but the issue was still there, so staying on 2.0.436 for now.

[dibarbet]

@winzig would you mind sharing the output of dotnet --info here as well? Looks there was an error running it (to be fixed by #6334)

[dibarbet]

From the logs:

Thanks - the dotnet info looks fine.
@winzig can you confirm that it is broken in 2.0.448 as well? If it is I'm almost certain it is related to
dotnet/roslyn#69769

[winzig]

@dibarbet I'm not seeing 2.0.448 in the releases for vscode-csharp?

[dibarbet]

Apologies - we had to redo the version numbers so 2.0.448 = 2.1.2. So most likely caused by dotnet/roslyn#69769. Will followup on their side to see what we might need to do.

[dibarbet]

Another report here - #6346

[dibarbet]

Update -

We've been able to reproduce this and are looking into the best way of fixing this. As a temporary workaround I think if you install the .NET 7 SDK alongside the .NET 6 SDK it should allow the project to load successfully.

[b26168]

I just rollback to v2.0.436 for workaround.

[dibarbet]

Currently tracking microsoft/MSBuildLocator#243 as a potential fix. Will need to update the server to consume this new version once it merges.

[dibarbet]

We just released version 2.3.27 of the C# extension which should resolve this issue.

If you're still having issues after upgrading, please open a new issue. Thanks!

[winzig]

Thank you, WFM

[michaelmarziani]

Syntax highlighting, cmd+click, and on-hover info is working again for me. Thanks!

[sliekens]

v2.3.27 works great for me in Debian Dev Containers, thanks!
