FYI - @arkalyanms

I suspect this might be caused by dotnet/vscode-csharp#7514

@skleg - two requests

1. Let me know if C# extension version 2.45.25 fixes the issue
2. If it does not, please set dotnet.server.trace to Trace, and attach the 'C#' output window logs here the next time it happens.

Thanks @dibarbet , the version 2.45.25 seems to fix the issue. I have been able to work for a few hours yesterday w/o any problems.

Thanks for confirming! Closing this issue
