@allnnde Could you share your OmniSharp log ?( View --> Output --> OmniSharp Log)

[allnnde]

i'm not have any log for Omnisharp

[rchande]

@allnnde Can you share your C# extension log?

@rchande

i'm having the same issue (no intellisense) with version 1.15.2.
No output for c# or omnisharp.
I opened the developer tools and found this:

[Extension Host] Activating extension 'ms-vscode.csharp' failed: Cannot find module 'rxjs/Subscription'.

@juwens Can you share your environment data (similar to @allnnde )

@juwens Thanks. I just installed the extension on a clean machine and wasn't able to reproduce that. Can you try deleting "%userprofile%.vscode\extensions\ms-vscode.csharp-1.15.2" and reinstalling?

[juwens]

@rchande i tried that previously without success

But i found the source of the problem on my computer.

Apparently my (installed) npm 5.6.0 is not compatible with node 10.4.1.
So i updated it to 6.1.0.

Now omnisharp and intellisense work fine again.

@rchande As I said before, I do not have any log, sorry for my english

[juwens]

@allnnde
please try the following:

Help > Toggle Developer Tools
In Developer Tools go to Console and look for errors.

@juwens Interesting. npm isn't a requirement to use VS Code, but I guess it must try to use your local copy if you have one installed?

[allnnde]

[allnnde]

I deleted in %userprofile% the folders .onmishap and .vscode\extensions\ms-vscode.csharp-1.15.2 and reinstall and now it is working ok

[rchande]

@allnnde Thanks for following up--glad you got it working!

[shubhcosmos]

Thanks @allnnde your workround was wonderful . I found two folders vscode\extensions\ms-vscode.csharp-1.16.2 and vscode\extensions\ms-vscode.csharp-1.16.1 .

Uninstalled extension closed vs code , deleted these two folders and reinstalled .

Everything worked .

Even the intellisence which was not working started working.
