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

commented

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!
