Extension Won't Load -- ms-dotnettools.csharp : Timed out while searching for 'workspaceContains'

[davidvmckay]

p.s., cannot use the extension to "prefill this information" because the issue I wish to report is that the extension won't load:

When I try to use the "prefill" command, the Error I see is Command 'CSharp: Report an issue' resulted in an error (command 'csharp.reportIssue' not found)

To prefill this information:

1. Open Visual Studio Code
2. Bring up the command palette (press F1)
3. Type CSharp: Report an issue

• If the CSharp: Report an issue command doesn't appear, make sure that you have C# extension version 1.17.0 or newer installed.

synopsis

After vscode update to 1.63, the c# extension (ms-dotnettools.csharp, a.k.a omnisharp-vscode) refuses to load. Based on logs from the Extension Host, this seems to stem from a change in vscode 1.63 meant to avoid hangs when loading unresponsive extensions: https://code.visualstudio.com/updates/v1_63#_timeout-of-workspacecontains

additional context

• The same problem happened with several other language extensions, including Harbour and GoLang -- but most other extensions continued to work normally.
• There likely needs to be a correction for the activation criteria used by each of these extensions to comply with VSCode's new 7-second timeout for the workspaceContains activation event + glob pattern - or a workaround setting or command to bypass that activation event.
• downgrading to omnisharp-vscode v1.23.16 failed to resolve the issue for me
• I also tried upgrading to omnisharp-vscode v1.23.18 beta 2 , but got the same results.
• Downgrading to vscode v1.62 worked.
  • for reference, based on Extension Host logs, loading the extension seemed to take about 2 seconds... but i guess it could have been 8 seconds and the log entries don't quite reflect reality. it may also be something other than a timeout, and whatever changes implemented the workspaceContains timeout broke something else about glob patterns for that use case...

C# Extension version:

v1.23.17

OmniSharp log

NO LOG - extension never loads

Steps to reproduce

1. use ms-dotnettools.csharp v1.23.17 Visual Studio Code v1.62.3 for x64 macOS to open a workspace including with multiple folders each containing a .csproj and accompanying code files
   1. see that this works fine, analyzers, hover tips, autocomplete, and dependency navigation function as expected
2. use the in-app Check for updates functionality to upgrade Visual Studio Code to v1.63
3. see that the same workspace no longer exhibits any of the syntax-aware features provided by omnisharp (although syntax highlighting still works, it is likely not provided by the same language service)

Expected behavior

Continue to have functioning C# analyzers, hover tips, autocomplete, and dependency navigation.

Actual behavior

The omnisharp-vscode extension doesn't even load (Actually the extension is registered as ms-dotnettools.csharp)

[davidvmckay]

omnisharp-vscode v1.24.0-beta1 tried to simplify the glob for workspaceContains via omnisharp v1.38 (commit), but this was inadequate to overcome the 7-second timeout in my environment.

[davidvmckay]

One thing that helped was removing a lot of projects / folders from my workspace. This brought the glob time down under 7 seconds, and Omnisharp was able to load.

But now I need to create a whole bunch of other workspaces and switch between them frequently, so not ideal.

Another thing that helped was just using a faster computer - but clearly that is not a scalable solution.

Yep - just realized the reason i didn't have language server for c# running was this particular issue:
