Uninstalling and updating an optional workload

[marcpopMSFT]

.NET SDK managed workload update:

• Basic update implementation: Workload update #17642
• Add offline caching and print download link: Adding offline caching for workload update #17766
• Empty feature band special case path: https://github.com/dotnet/designs/pull/188/files#diff-9a9e0dee8b9d58f8e2cacc7a55069aaee49f367fec2ac0c6dd943f91f68026bbR141-R144: Implement cross feature band workload update #17933

.NET SDK managed workload uninstall:

• Basic uninstall implementation: Implement workload uninstall #17937

• Need to have an option to check all (workload, SDk, runtime) at once. We need an explicit command for sure.
• Check the last manifest from nuget manifest feed for workload
• Check release.json (convert it to nuget package?) for SDK and runtime (dotnet sdk check)
• Garbage collection for the packs (given SDKs and what’s one disk and manifests as input. There could be multiple SDKs)

Removing "Implicit check for update (check periodically or tie to a command. Check for update of project and check for SDK should be able to be distinguished by the user) below cutline." as it's tracked by #17394

[sfoslund]

Check update with explicit command. Same logic for both non admin and VS/standalone installer since there is no permission issue. (add to dotnet --info too?)

@wli3 does the list PR you have out now cover this? Or does that only advertise when the print urls option is set?

[wli3]

@sfoslund it is more for #17394 if we decide not to a background check, but an explicit check instead. I will just remove the line here.

Now that cross band update has been merged, all of these items are finished, closing.
