OmniSharp intellisense not recognizing new class file

Question

I have a dotnet core console app I generated from the cli via

dotnet new console -n EODG.VsCodeTester.Cli

Using the C# Extensions extension, I right click on the project folder in VSCode, and click "New C# Class".

The class/file opens just fine, but Omnisharp doesn't appear to recognize the file/class. From Program.cs, the class doesn't show up in the code completion, and the codelens in the new class doesn't show up.

The following is outputted from the OmniSharp log...

[info]: OmniSharp.Roslyn.CSharp.Services.Completion.CompletionService
        Could not find document for file c:\Users\elrod\src\test\src\EODG.VsCodeTester.Cli\Cat.cs

Now, if I restart OmniSharp, it recognizes the new file just fine... but it's kind of a pain to restart omnisharp everytime I make a new class/interface or rename them. I've never seen this before, and I've been doing dotnet core development in vscode since v1.

I tried googling OmniSharp "Could not find document for file"... and it said No results found for OmniSharp "Could not find document for file".... so, that's nice.

Pertinent Details

• OS: Windows 10 (fresh install... like less than 2 hours old)
• VSCode version: 1.50.1
• OmniSharp version: 1.23.5
• Dotnet version: 3.1.403

I will be more than happy to provide any other details I can.

Thanks, y'all!

Answer 1

What worked for me on my mac, was that in settings, search for omnisharp, then look for the option that says Omnisharp: Use Global Mono and set it to always.

Answer 2

It looks like OmniSharp version 1.23.5 might be busted... I reverted to version 1.23.3, and things work as expected now. Possibly related to this issue on their git repo.

UPDATE: updating to v1.23.6 resolves this issue.
