@tmeschter is devkit calling out to C# here - or is this an error talking to a different service?

Oct 25 '23 21:10 dibarbet

Looks like devkit is losing the connection to the C# extension.

@Anurella would you mind changing the dotnet.server.trace configuration to Trace and posting the logs from the C# output window as well when you hit this issue?

@dibarbet may I ask what the steps are to make the change? I would also look out for it once the change has been made.

Oct 25 '23 23:10 Anurella

@Anurella modify the value in vscode settings, then reload the window (cntrl+shift+p, type 'reload window')

Then share the contents of the C# output window. Thanks!

@dibarbet please see below content, tried to take the earlier bits as the output was a lot to paste on here

Thanks - based on those logs it doesn't appear as though anything is explicitly going wrong in the C# extension, it looks like it is still running.

A couple more things to confirm

After you hit this error - is there still a process for the C# server? You can check by looking for a process with 'Microsoft.CodeAnalysis.LanguageServer.dll' in the command line. For example in powershell:
```
Get-WmiObject Win32_Process -Filter "name = 'dotnet.exe'" | Select-Object Name,ProcessId,CommandLine | Select-String 'Microsoft.CodeAnalysis.LanguageServer'
```
Will output something like this if it exists:
Can you zip up and attach the contents of the extension logs folder? You can find it here:

Oct 27 '23 23:10 dibarbet

Hello @dibarbet please find zipped folder. I hope it helps logsa.zip

Oct 30 '23 08:10 Anurella

@Anurella apologies for the delay, taking a look at the extension logs now, a bunch of logs appear to be missing. I'm not seeing any of the output window logging which is super important. Best way to get these

Open VSCode, run the steps to reproduce the issue
From that same VSCode instance, open that extensions log folder, and include everything inside it. If you'd rather not post it on a public github issue, feel free to send to my microsoft email ([email protected]).

Thanks!

Thank you @dibarbet. I have sent the email

Nov 23 '23 09:11 Anurella

Thank you @dibarbet. I have sent the email

Got it- thanks! Will take a look this week.

Nov 27 '23 19:11 dibarbet

Aha - this log has the correct details - thanks!

The error:

[Error - 8:36:53 AM] [LanguageServerHost] System.InvalidOperationException: didOpen received for virtualcsharp-razor:///<file path>.cshtml__virtual.cs which is already open. - line 106

This is potentially the same as https://github.com/dotnet/vscode-csharp/issues/6644, which will hopefully be fixed in this weeks release. However its hard to tell without the solution file.

@ryzngard would you mind taking a look here since this looks like an issue on the Razor side? I am seeing two entries for the same file in the Razor log:

Trying to create DocumentContext for textDocument/didClose for (no project context) for file:///<path>/SliderSection.cshtml
...
Trying to create DocumentContext for textDocument/didClose for (no project context) for file:///<path>/SliderSection.cshtml

Nov 29 '23 02:11 dibarbet

Agree this looks the same. @Anurella can you confirm if there is a possible difference in casing somewhere in your csproj files and on disk naming?

Dec 04 '23 23:12 ryzngard

@ryzngard there is no difference in the naming, only one file exists.

Or can you help clarify what you would need me to check specifically. Thank you

Dec 05 '23 09:12 Anurella

@Anurella is there a solution you can share? Either or on GitHub or private e-mailing me ? That would be the easiest way for me to verify

Dec 05 '23 21:12 ryzngard

@Anurella , if you have a solution that repros this issue, can you share it with us so that we can diagnose the particular cause of the issue?

Jan 18 '24 22:01 phil-allen-msft

To be honest I am not sure I have. I sent the log files to @ryzngard when I encountered it.

Not worked on the file in a minute so I have not had to encounter the issue. But I think it might be a case of the razor formatter and prettier being active at the same time.

Jan 23 '24 09:01 Anurella

Let me double check my email, I have a few logs sent to me and for some reason thought this issue I didn't get them.

Jan 23 '24 21:01 ryzngard

I apologize @Anurella but I can't seem to find the e-mail. Do you mind resending? I checked spam just in case as well but no luck.

Jan 23 '24 21:01 ryzngard

I am sorry it was @dibarbet I sent it to initially, but I have sent it to you now. Do let me know if you get it.

Feb 04 '24 14:02 Anurella

@Anurella I don't see the initial error in the logs you sent, but I do see a lot of exceptions around SemanticTokensRange being incorrect on request. This looks like it might be similar to https://github.com/dotnet/razor/issues/9598 (and others that we haven't correlated yet, but I'm sure we have). Can you confirm you're seeing those exceptions normally?

The original exception I was looking for, Project system data flow 'Workspace update handler... was not contained in the logs
