@dmumladze Thanks for including your omnisharp log. Can you try deleting the C:\Users\{username}\.vscode\extensions\ms-vscode.csharp-1.14.0\.omnisharp directory and see if that helps? Also, it looks like you’re on a pretty recent release of the CLI. Have you updated the CLI recently, and if so, was everything working before you updated?

Disable the C# plugin and the error messages will go away (KISS).
