Roslyn Analyzer works even though I disabled It

[MuhammadKotb]

I don't like analyzing my code while Editing So I Disabled the Roslyn Analyzer through Enable support for roslyn analyzers, code fixes and rulesets setting

But It still works even after restarting language server and restarting vscode

I switched to version v1.26.0 and Everything is working fine

This is a side effect of switching to the new roslyn based language server as a default in the latest version of the extension. For now as workaround you can either downgrade or set the dotnet.server.useOmnisharp flag to get back the old behavior.

This is an option we should consider in the new roslyn based language server as well

I upgraded to the latest version and set dotnet.server.useOmnisharp to true and restarted vscode but unfortunately the behavior did not change

Hmm that's definitely unexpected. Mind sharing your C# / Omnisharp logs from the output window when you have the 'dotnet.server.useOmnisharp' setting checked?

from c# output Dotnet path: /home/kotb/.config/Code/User/globalStorage/ms-dotnettools.vscode-dotnet-runtime/.dotnet/7.0.9/dotnet Activating C# + C# Dev Kit + C# IntelliCode... info: LanguageServerHost[0] Starting server...

these are the available outputs

Ah gotcha, thanks for the additional info. When the devkit extension is installed, the dotnet.server.useOmnisharp option is ignored - this is because devkit requires that the C# extension is launched with the new Roslyn LSP based server.

In order to use the dotnet.server.useOmnisharp flag, C# devkit needs to be uninstalled or disabled.

[MuhammadKotb]

Is there any chance to fix it ?

[tommyvct]

Mine have the same behaviour, but from the C# output log it will stuck at Starting server... indefinitely.

[tommyvct]

I want to use the IntelliCode extension but it depends on the C# Dev Kit, which will enforce the use of Roslyn. But it's so broken that the language server can't even be started, which renders the whole C# thing unusable.

I'm on openSUSE Tumbleweed with .NET 7.

UPDATE: I somehow fixed it by disable and reenable the dev kit extension a few times.

Really? Unexpected? Considering latest few releases this kind of stuff becomes rather greatly expected. "Oh, look, they released a new version of C# extension! LET'S SEE WHAT DID THEY FUCK UP THIS TIME, SHALL WE?"
