Hi,
I'm in Mac, maui 9.
% dotnet --list-runtimes
Microsoft.AspNetCore.App 8.0.5 [/usr/local/share/dotnet/shared/Microsoft.AspNetCore.App]
Microsoft.AspNetCore.App 9.0.1 [/usr/local/share/dotnet/shared/Microsoft.AspNetCore.App]
Microsoft.NETCore.App 8.0.5 [/usr/local/share/dotnet/shared/Microsoft.NETCore.App]
Microsoft.NETCore.App 9.0.1 [/usr/local/share/dotnet/shared/Microsoft.NETCore.App]
How to update runtimes only for 9 and remove old runtime 8.
% dotnet workload list
Installed Workload Id Manifest Version Installation Source
maui 9.0.14/9.0.100 SDK 9.0.100
Use dotnet workload search to find additional workloads to install.
Is it maui for 9 ?
thanks in advance,

currently MS does not have a complete reliable solution to remove outdated dev tools.
note: this why when I upgrade hardware, I only import user files and reinstall applications.

2025-01-30T20:53:13.7166667+00:00 the project files define the runtime and sdk version, not which sdk is installed. the sdks install side by side. so the .net 9 dotnet.exe can build .net 8 applications, but the .net 8 libraries need to be available. to run .net 8, the proper .net 8 runtime must be installed (separate from the sdk).
