[Megathread] Engineering Status of RID Improvements and Publish UX Changes

[nagilson]

This is to help me keep organized on what I still need to implement for the issues specified here by @richlander and resolves #26446 and so others can see the progress on those issues. I will be closing them out as well, but this may be helpful.

PR 1) #26143

• 0) Use implicit RID in the following situations:

  • For any publish property that requires a rid, use the default RID, just like if --use-current-runtime is specified.
    That means:
    • SelfContained
    • PublishAot
    • PublishReadyToRun
    • PublishSingleFile
    • PublishTrimmed
    • PublishSelfContained

• 1) Add PublishSelfContained property.

  • Set self contained to true automatically when we're publishing
  • Make sure it takes precedence over self-contained=false

Remaining:

• Make sure this doesn't break rid agnostic projects.

PR 2) _____

• 0) Add RuntimeSpecific property.
  -> Sets self contained to false
  -> Uses the implicit RID (portable one)

  Verify:

  • Make sure you can still specify -r runtime without it being overriden.
  • Make sure you can still specify self-contained to true even if you do /p:SelfContained=true.

PR 3) ______

• 0) Add --ucr shorthand for use-current-runtime.

PR 4) ______

• Add PublishRuntimeIdentifier property.

Looks good!

I'd say that the --ucr request is lowest on the list.

All of these are done except RuntimeSpecific, which is here #28412 and waiting for 8.0 SDK Build changes. Going to close this!
