System.InvalidOperationException: We don't have an MSBuild to use

[Dreamoochy]

I've updated to .NET 8, VSCodium 1.84.2 and free-vscode-csharp v2.10.28.
Now at the start I get the following notification for each project in a workspace:

[Error - 9:41:41 AM] [LanguageServerProjectSystem] Exception thrown while loading %file_path_of_csproj% StreamJsonRpc.RemoteInvocationException: We don't have an MSBuild to use; HasUsableMSBuildAsync should have been called first to check. - line 133

Same for me, is .NET 8 support coming?

in the meantime any workaround is appreciated.

Can't reproduce. What OS are you using? Try updating the extension to v2.12.19

[herbertsschaefe]

Apparently fixed!

The problem was consistent in all Unity3D projects after updating .Net Code to 8.0.
OS: Arch Linux
free-vscode-csharp: v2.10.28
VSCodium: v1.84.2

After updating to v2.12.19 the behavior does not occur anymore in any project.
Thank You!
