VS Code using resouces when Visual Studio is building #4683

Open Sti2nd opened 3 years ago

Sti2nd commented 3 years ago

Issue Description

I have both Visual Studio and VS Code open on the same project as I like VS Code best but Microsoft still wants VS Code C# functionality to be "Lightweight development tools for .NET Core"... forcing me to use VS for some functionality. This has been working fine up until recently. Recently I noticed building in Visual Studio took way longer. I found that VS Code that I had open in the background used most of the resources and that it was spawning more than 500 .NET Host processes. My computer froze, so in the image below there are only 253 processes from VS Code.

Steps to Reproduce

I can't reproduce it, it just happened after a while of using both VS Code and Visual Studio.

Expected Behavior

Able to have VS Code open while using Visual Studio without VS Code using much resources.

Actual Behavior

VS Code spawns many many processes. image

Logs

Unfortunately I closed VS Code before I found out about the "report an issue" command, so I don't have any logs.

Definitiely something funky going on with Omnisharp. It used 1 minute and 8 seconds (and 100% CPU utilisation) to build two projects that Visual Studio use 10 seconds on. It's almost as if Omnisharp rebuilds the same project several times concurrently instead of just once.
