Open JohnGalt1717 opened this issue 3 years ago • 3 comments

Issue Description

When using .NET Preview 7, Omnisharp correctly picks the preview sdk, but then errors with:

Failure while loading the analyzer reference 'Microsoft.CodeAnalysis.CSharp.CodeStyle': Could not load file or assembly 'Microsoft.CodeAnalysis, Version=4.4.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35'. The system cannot find the file specified. VS.net works fine.

Steps to Reproduce

Install latest .net 7 preview 7. Create a console app: dotnet new console -o whatever Open in VScode Add some code.

Check the output logs for Omnisharp.

Expected Behavior

Should work as normal

Actual Behavior

No intellisense

This is because the current version of Omnisharp v1.25.0 has no support for Roslyn (Microsoft.CodeAnalysis) Version=4.4.0. It supports up to 4.3.0, if you look at the changelog for the 1.25.1-beta1 version here you will see this beta version supports Roslyn 4.4.0, so installing this beta version will fix your problem.

To install a beta version use this manual from the wiki.

Hope this helps.

This also cause problem to browser-wasm project in dotnet 7.0 too. Hope this will got out of beta soon

Try to uninstall the C# extension from VS code , close and open vs code and then install the extension again, it worked for me, it started working normally again

VinyJos avatar Nov 25 '22 05:11 VinyJos

Yes the latest version shipped with Roslyn 4.4.0

filipw avatar Nov 25 '22 07:11 filipw

I have the latest version of the C# extension, and versions 6.0.400, and 7.0.100 but VSCode doesn't work when I load a Net6.0 project, Why is that?
