Errors any time a .razor file is in a non-building state

[rally25rs]

Type: Bug

Issue Description

Steps to Reproduce

Open a Blazor .razor file.

Edit anything, especially letting copilot partially autocomplete, or paste a chunk of code that isn't 100% correct.

C# extension errors any time a .razor file is in a state where there are edits that don't compile.

Expected Behavior

Don't error. Or at least don't bubble up a notification toast message in VSCode every time.
Every time you tab complete a copilot completion, or paste a chunk of code, I don't need a popup error to let me know the file doesn't compile.

Actual Behavior

@rally25rs The error log indicates that the source generator doesn't like something about your Components/ConfirmDialog.razor file. Can you share more details about your project so we can try to work out what the issue is? Do you have two files with the same name, but different casing?

/cc @chsienki if you think of any extra info or steps here

[rally25rs]

@davidwengier

It's a private repo for an employer so I can't directly share the code. I might see if I can distill down a sample repo if I get time.

There are 2 ConfirmDialog.razor in the .sln, but they are in different Blazor projects that are not associated in any way (there is no dependency between them).

This error also shows up when editing any razor file, whether that file references ConfirmDialog or not, and there are no edits to ConfirmDialog.razor.

I've been having this as a reoccurring issue for something like 6 months, and it seems to happen more often after a couple hours of editing, especially when using CoPilot heavily, copy/pasting entire files or large chunks of content around, and renaming things.
Then it will go away for a while, and come back after a couple hours of editing again.

I'll try to pay closer attention for whatever I was going the moment it start happening again...

[davidwengier]

The error showing up all the time is expected, source generators are run for a whole project at once, they're not granular to just the file you are editing. Perhaps try using the Collect Logs command and capturing an activity log when its happening, that might tell us more?

[jvalore-nimblepros]

Ran into errors starting to pop up again this morning. Slightly different error, but this time I got an error message when I didn't even have a file open, nor was I editing anything.
I had Copilot in Plan mode working on a plan, and came back to the error toast message:

The error message is

The solution does have a Components/PatientInfoPanel.razor file.

[davidwengier]

Copilot can use the LSP server to find out info about your project, so this isn't necessarily surprising. Collecting logs would be the most useful thing, even if you just manually set the C# and Razor Log levels to debug or trace, and then just copy everything out of the output pane into here if/when it happens next. To set the log level, bring up the Output pane, switch to "C#", then click the little cog icon next to the drop down and select debug. Do the same again for "Razor Log" (the most important one in this case, most likely) and then let them just collect in the background.

[jvalore-nimblepros]

bring up the Output pane, switch to "C#", then click the little cog icon next to the drop down and select debug

Super helpful, thanks. I never knew there was a log level setting there.
I cleared existing logs, set those 2 to Debug, and will monitor for the next error.

Thanks again for the assistance.

[davidwengier]

On the contrary, you're the one assisting me, it's my bug 😛

[rally25rs]

Finally managed to catch some logs while in debug logging...

Thanks for the logs. They point to the same problem, but a different file, and possibly a different project. Unfortunately they don't capture anything super useful about the project as to why this might be happening. There is more logging coming in future that might help (eg dotnet/roslyn#83680) though that would be from an explicit command.

Perhaps next time you hit this you could capture a dump from the "Collect C# Logs" command and send it through? Best to send a link to it privately though. My email is david dot wengier at microsoft dot com.

@davidwengier I emailed you a link to a dump file.

Got it. I had a quick look, and there doesn't seem to be anything obviously bad, but its almost 11pm and I'm just on my Windows laptop trying to poke at it. Will try tomorrow with an ARM Mac and should get further with things. Windows doesn't like Mac dumps :)
