Type: Bug

Every time i try to open the .NET MAUI repo, i get a failure on the named pipes. I have removed the folder manual of the extension and restored all extensions again .

Using dotnet configured on PATH

@rmarinho - if you change the dotnet.server.startTimeout configuration in vscode settings to a higher value (say 60000), does the error still appear?

Nop, didn't help. even with updated version

That is weird - basically on the client side we're timing out waiting for that 'pipeName' message - but it does look like the pipe name is being sent (the last line in your logs). No matter how much you increase it, is that pipe name message always sent after it times out?

A couple more things to try

  1. Set the dotnet.server.trace configuration in vscode settings to Trace, and paste the C# output window logs here
  2. When you encounter that error, can you check if the language server process is running? Something like ps -ef | grep 'Microsoft.CodeAnalysis.LanguageServer'

I wonder if this is related with our cake scripts that launch vscode.

You could try to repo by cloning dotnet/maui

From home directory after installing .net8 sdk

sudo dotnet workload install maui

From dotnet/maui folder

dotnet tool restore
dotnet cake --target=VSCODE --workloads=global

Thanks for the updated logs. So a couple things

  1. There is an issue on the extension side where if the client failed to connect to the named pipe it would be reported as a time out. The next prerelease should instead output the actual error that happened in the C# logs.
  2. Other users mentioned here that this stopped working when local admin rights were removed - is that something that might have happened on your side? - https://github.com/dotnet/vscode-csharp/issues/6842 . a. Does your user have read/write permissions to the location where we're trying to create the named pipe - /var/folders/4q/9688kc6n3xjbpw46t_5r5zvm0000gn/T/9b238260.sock ?
  3. I'm working remotely at the moment and don't have my mac with me, I'll be back next week with my mac and will try it there. I tried on my windows box and didn't have any issues.

Closing, likely duplicate of https://github.com/dotnet/vscode-csharp/issues/6842 Please try out the latest version of the extension. If it is still not working, feel free to re-open and include the latest logs (and check item 2.a above).
