RUNTIME HARDENS UNSAFE CALLS WHILE MAUI FIXES MERGE PIPELINE

The CLR just shipped tooling to migrate LibraryImport toward unsafe-v2, plus allocation cuts in COM interop, while MAUI plugs gaps in its bot-driven merge policy.

EgorBo landed the big one: LibraryImportGenerator now participates in C#'s new unsafe-evolution rules [1], complete with an analyzer and code-fixer to automatically add `unsafe` keywords to existing [LibraryImport] calls that lacked safety annotations [2]. Nothing breaks under unsafe-v1, but this is the tooling your team needs before unsafe-v2 becomes the default. On the allocation front, Theodore Tsirpanis eliminated temporary array allocations in ComVariant.As by using `params ReadOnlySpan<VarEnum>` to reference RVA fields directly [3], a small win that compounds across high-traffic P/Invoke paths. Over in MAUI, two follow-ups landed on merge automation: PureWeen closed post-merge review findings on the finalize step [4], and fixed the bot-opened inter-branch policy to stop redundantly checking issue authors [5]. The team also ripped out blanket integration-test retries after discovering 98.2% of them reproduced identical failures anyway, cutting noise from the pipeline [6].

Action items

→ Audit existing [LibraryImport] calls and run the new fixer to prepare for unsafe-v2 dotnet/runtime [plan]
→ Test MAUI artifacts from the merge-policy fixes if you run inter-branch automation dotnet/maui [monitor]
