Whenever I open VisualStudioCode, I get a warning message saying "some projects have trouble loading"

However, there are no issues apparent in the full output, and the plugin works correctly:

I've seen the same thing -- especially for Unity projects.

[MetaDev]

Any fix for this?

[DustinCampbell]

It looks to me like this will be display for any project that contains warnings: https://github.com/OmniSharp/omnisharp-vscode/blob/d96fb0c6864b133a45f6a36bee5d45fc1885663d/src/features/status.ts#L236-L242

I am also experiencing this very frequently, and it keeps reappearing whenever I close it. Is there a keyboard shortcut to temporarily disable OmniSharp when this happens?

[bbugh]

I get this all the time too, and it's not only when project contains warnings. It seems like Omnisharp gets out of date with the reality of the project, and then starts to complain about false warnings.

Most commonly, the warning is about Type X doesn't exist in the current context (but it actually does) or The type X conflicts with imported type X from Assembly-Csharp-firstpass (where type X is the class in the current file, it can't conflict with itself).

Restarting Omnisharp always clears out these false warnings, but I'm having to restart Omnisharp once every 5-10 minutes now. There are no actual warnings or errors in my project, just these constant false hits.

@jamesqo you can dismiss the error with escape, or restart Omnisharp with the command palette.

[felschr]

Great to see this fixed now!

@bbugh
v1.7.0-beta4 also seems to have fixed the Type X doesn't exist in the current context errors for me.

[bbugh]

Awesome! Thanks so much for working on this @DustinCampbell. I hate to be the bearer of bad news, but the installation didn't quite work for me out of the box.

When I installed v1.7.0-beta4.vsix, it seemed to properly download all of the libraries, which I've never seen before. However, when Omnisharp ran, it threw an exception looking for ~/.vscode/extensions/ms-vscode.csharp-1.7.0-beta4/bin/gac. Omnisharp and Intellisense were not working at all. I verified that omnisharp.useMono was set to the default of false.

I was able to work around the problem by sym linking my global Mono package gacdirectory into the extension bin folder. I'm not sure if this is a good long-term solution but it's working for me. And as @felschr said, I'm not getting any of the many compilation warnings anymore, so I don't have to keep restarting Omnisharp. Amazing!!!

Here's what I did to work around it:

» cd ~/.vscode/extensions/ms-vscode.csharp-1.7.0-beta4/bin 
» ln -s /Library/Frameworks/Mono.framework/Versions/4.6.2/lib/mono/gac

Here's the stack trace from the error:

[DustinCampbell]

I wouldn't symlink that folder. That could cause other problems down the road. However, it looks like this issue was already filed at #1192. I'll work on getting a repro and fixing this.

[ruslansmax]

check folder url from special characters like !@#$%^&*() and delete those characters
