Looks like a related issue at https://github.com/OmniSharp/omnisharp-vscode/issues/4110

Downgrading from 1.23.3 to 1.23.2 fixes the problem for me for now.

[TCROC]

I can confirm that I also have this issue and that downgrading has also fixed it for me

[oskarious]

Running into the same thing, but downgrading to 1.23.2 does not fix it for me

[DaCapoAlCoder]

@oskarious What version of .net sdk are you running

[oskarious]

@DaCapoAlCoder 3.1.403. Was on 3.0.101 previously, but updating didn't seem to help unfortunately

[DaCapoAlCoder]

@oskarious Downgrading to 3.1.402 might get it working for you again. I've ran into an issue before where omnisharp broke after upgrading the sdk

[filipw]

this is resolved in https://github.com/OmniSharp/omnisharp-roslyn/pull/1984 which will be released with extension 1.23.4

[oskarious]

@DaCapoAlCoder Same on 3.1.402 unfortunately. Thanks for the help though, appreciated. I'll hold out until 1.23.4 which @filipw just mentioned. 🙏

@oskarious You also have to regenerate your CS Project files:

[JoeRobich]

A pre-release build of 1.23.4 is available at https://github.com/OmniSharp/omnisharp-vscode/releases/tag/v1.23.4. Please try it out and let us know if it resolves the issues you are seeing.

@JoeRobich After a cursory run through that seems to have fixed it

[breadnone]

Good god, every update from omnisharp makes my heart beats faster...

[filipw]

@JoeRobich After a cursory run through that seems to have fixed it

thanks for confirming
