dotnet maui updates

Question

I asked a similar question before and received an answer that helped some. I have learned more and now have a related but new question about this topic.

I update my Mac by downloading the latest DMG file from the dotnet download site and installing it. I then do a sudo dotnet workload update. When I run the dotnet sdk check command this is the result:

Microsoft.NETCore.App         9.0.1        Up to date. 

You can see several lines that show things like: Patch 8.0.12 is available. Then there is the line: Patch 9.0.1 is available, but right below that you see 9.0.1 is Up to date.

Does this mean if I wanted 8.0.12 then I would need to download that manually somehow or is there a way to "Patch" 8.0.10 to become 8.0.12 and is that preferred?

I have a similar question on my Windows VM in Parallels. The difference there is that I use Visual Studio releases to update that instead of manually installing the msi files.

.net core sdks and runtimes are installed side by side in separate folders. So if you install a patch, you still have the unpatched version. You can uninstall early versions and only keep latest patch version. If you don’t need you can also remove out of support versions.

.net app are built to a particular runtime, so a .net 6 app will not use a .net 8 or .net 9 runtime, even though .net 6 runtime is out of support. The app needs to be upgraded. When an app run, it finds the latest patch version of the runtime it was built against (but can be pinned to a particular runtime version.

note: your .net 8 runtime is not the latest. Installing the lastest .net 9, does not patch earlier versions. You need to download and install the latest of each version.
