Visual Studio stopped responding for 9 seconds. Disabling the extension CSharpier 1.5.1 might help.

Multiple times a day I get this message. "Visual Studio stopped responding for 9 seconds. Disabling the extension CSharpier 1.5.1 might help."

Here is the CSharpier output:

I released a new version of the extension today that I hope will address these problems, or at least make them easier to track down.

The latest (1.5.2) version has a new option "Use CSharpier Server", could you try the new version with that on to see if it resolves the issue?

You'll get a windows firewall popup about dotnet-csharpier needing internet access, which it doesn't. The extension communicates with the cli over http with this new version. I resolved the firewall warning in that in #1184 but it hasn't been released yet.

[mejobloggs-cw]

It's still happening, but there's a lot more logs now.

This is without the new "Use CSharpier Server" option enabled

Ok yeah, still getting the "Visual Studio stopped responding" message sometimes while using the Server option.

[belav]

I'm thinking there is either something in some of your files that csharpier can't handle. If it is all files in the project, then maybe something in an .editorconfig.

If you create a new file with a basic class in your project, can that be formatted?
Are you able to share the contents of the project?
If you run dotnet csharpier . in the project, does that work?

[mejobloggs-cw]

I created a new "ASP.NET Core Web API" project with Identity.

Closed VS, opened the project, and got the error again "Visual Studio stopped responding for 9 seconds. Disabling the extension CSharpier 1.5.2"

So it's not the code from my other project or editorconfig. I double checked and no editorconfig is present in the new webapp

[belav]

The logging from the extension side doesn't really give me any indication of what the problem is. I hope to add logging to the csharpier side, but I don't know how soon that will happen.

The only other thing I can think of is for you to debug csharpier.

• clone csharpier
• open the cshaprier sln and build it
• open the troublesome sln in a separate window
• open options - csharpier
• set custom path to [csharpierRepo]\Src\CSharpier.Cli\bin\Debug\net8.0
• enable the "use server" option - it should be easier to debug
• back in the csharpier sln, attach the debugger to [csharpierRepo]\Src\CSharpier.Cli\bin\Debug\net8.0\dotnet-csharpier.exe
• format a file in the troublesome sln
• back in csharpier pause the debugger, and see where csharpier is getting hung up. I'm assuming it must be stuck in a loop somewhere because of the 60 second timeout.
• If that doesn't work, the entry point is Src/CSharpier.Cli/ServerFormatter.cs

[mejobloggs-cw]

I'll give it a try but the issue usually doesn't happen when I format a file, it usually happens when I first open Visual Studio.

So I think the method of attaching to a process is too late because I think the issue is in the process start/warmup

Also I notice in Task Manager one dotnet-csharpier.exe starts for each Visual Studio instance. But when I close Visual Studio, dotnet-csharpier process still exists.

As of right now I have 0 Visual Studio open, but 5 dotnet-csharpier in Task Manager.

Perhaps this is intended behaviour to make next launch faster, not sure, just thought I'd mention it

[parched]

@belav I get this too every time I open VS,

We're using 0.28.2 in this project.

How should I go about investigating the issue?

[ChrisGoettfert]

any updates on this? the only solution I found is uninstalling/reinstalling Csharpier (and everytime I open up a solution...)

[belav]

I haven't been able to reproduce the problem but found a couple of things that I believe are related.

The extension will no longer try to warm csharpier for any open documents on solution load. It will also no longer warm csharpier for those open documents the first time you right click on them - that had a noticable delay with rendering the right click menu. Warming csharpier still happens when you open/switch to a c# file, but it happens in the background and generally isn't noticable.

Warming is essentially - finding the correct version of csharpier for a given file, ensuring it is installed and then formatting a small file because the first file it formats is a bit slower than anything that follows.

Those changes are out in 1.9.3, let me know if that seems to have resolved the startup issues.
