.NET 6 SDK installer doesn't uninstall cleanly

danroth27 commented 3 years ago

Repro steps:

Install .NET 6 Preview 6 SDK (6.0.100-preview.6.21321.10) on Windows
dotnet new blazorserver -o BlazorApp
cd BlazorApp
dotnet watch
Ctrl+C to stop running the app
Uninstall .NET 6 Preview 6 SDK

Expected result: SDK uninstalls cleanly

Actual result:

I get multiple "Files In Use" errors at various points during the uninstall for ".NET Host"
After selecting "Close the applications and attempt to restart them" multiple times, the uninstall eventually succeeds
But, the 6.0.100-preview.6.21321.10 folder is not removed from the dotnet/sdk folder. The folder is empty, but must be manually removed to avoid errors when installing other .NET SDK versions.

We would need setup logs before investigating. Likely it uninstalled the the SDK first and then got to the error in the host later which likely resulted in the SDK folder not being empty. The files in use, there is nothing we can do and is completely in control of the OS. I advise not spending a lot of effort investigating this as uninstall is notoriously tricky wrt files in use.

I'm happy to collect whatever you need. Any pointers on how to collect these logs?

I wonder if we have .NET processes that are not shutting down cleanly during development?

Old issue triage: we've made improvements here and the host running can cause issues.
