Constant Request textDocument/semanticTokens/range failed. error in vscode

[LiamMorrow]

G'day, I've been using the c# devkit extension in vscode and have noticed that when editing razor files it constantly shows errors as notifications, simply when navigating to any razor file.

Request textDocument/semanticTokens/range failed.

Note this happens on both the current release, and the prerelease.

To be honest, I'm not too fazed about the intellisense and that not working. If there was a way to disable these error notifications (you can't disable errors notifications in VSCode without a CSS hack), or downlevel them to warning that'd be immediately much better for me

@LiamMorrow , we've recently made some changes that are in the C# Extension for VS Code version 2.22.5 related to the handling of the casing of paths; does that resolve this issue for you?

I have this even without the c# devkit extension

[chandrashekharjoshi-abb]

This issue is extremly annoying, first of all intellisense doesn't work and on top of that notification keep popping even when we type a single word. Turn of notification also doesn't work.

Sorry for the delay @phil-allen-msft it's been a hectic couple of weeks as I'm moving rn.

Currently running v2.24.17 (prerelease) and I haven't seen the issue after a brief play around 🎉

I found the solution for my use case, i had a solution which had Blazor projects from different repos and not part of same workspace, if i open them in separate Workspaces or open the root folder where alll repos exist then no issues.

This issue is extremely annoying. It keeps spamming these messages in the bottom right:
"Request textDocument/hover failed." and "Request textDocument/semanticTokens/range failed."

[LiamMorrow]

Yeah unfortunately it is back for me as well. It's not a small repo, but this is where I can reliably reproduce it

I've had this issue since start of 2023, it comes and goes. Sometimes it works fine but mostly it's just spitting errors.

Is there any ETA on this fix, I feel like this should be important since the C# DeKit extestension is supposed to be "the new thing" for VSCode C# development and right now it's not very usable.

[LiamMorrow]

It keeps spamming these messages in the bottom right:

@SamuelChih I just discovered this setting in vscode. It doesn't fix the problem that it is having, but it does stop it from causing that flood of notifications.

I have also observed that snap version of vscode has this issue, installed using below commands and after that i faced no issue

echo -e "${Highlight}Installing vs code...${NC}"
# sudo snap install --classic code
