Managing Installed Runtimes and SDKs on system

Question

Running dotnet sdk check I see many versions of sdks and runtimes. Some I can't find when I got to add/remove programs. I'm trying to understand how to manage them. For example: I see that there's 5.0.7 runtime that needs a Patch which is listed as 5.0.8 yet I have 5.0.8 installed.

What process should one follow to have a "healthy" system

Answer 1

In your case you are missing the latest 3.1.* patch. You should install it. You really only need the lastest patch for each x.x version you use.

For example 2.1 will reach end of support next month. You should really migrate your code off of it to a later version.
