Hello @dotai2012,

I've attempted to replicate this but am not seeing this behavior with DevSkim 1.0.11 on Windows, the .NET process appears to properly quit when VS Code is closed. I'll attempt to replicate today on Ubuntu.

I'm able to replicate this on Ubuntu, but am not yet sure how to resolve it. The design of the extension delegates responsibility for the lifecycle of the Language Server process to the VS Code library for the Language Client which launches and then connects to the server. Its not clear why it would properly close the processes on Windows but not on Ubuntu but will investigate more.

This issue doesn't appear to be present in Bicep which uses a very similar design including also using the omnisharp language server library, which may be useful as a reference to identify the issue.
