Proposal: C# 9 "Init-Only" properties in XAML

Init-only properties are a set-on-initialization-only accessor in C# 9. Morten has suggested that we bring this to XAML: https://twitter.com/dotMorten/status/1263284520364564481

Interesting idea to explore. It would allow the instantiation of read-only / immutable values in XAML markup.

Summary

Unsure if this would require a syntax change/expansion in XAML...?

Rationale

(it would be great if Morten or others could articulate additional rationale & scenarios here--I'm just blitzing Twitter notifications right now so doing light initial job on this proposal)
