The .NET runtime shed a test dependency on XML serialization while Orleans spent the day restoring critical guidance that vanished in a recent docs overhaul.

Andy Ayers landed a surgical refactor of a JIT test that removes its reliance on the XML serializer, keeping the original bug detection intact [1]. Meanwhile, the runtime team fixed build breakage on haiku and illumos x64 platforms [2] and patched a stackwalking bug in the compact DAC discovered during internal diagnostics [3], the kind of low-level fix that saves hours of production debugging later. On the Orleans side, Reuben Bond shipped a hardened DynamoDB transactional storage layer that now requires a successful reload after failed stores and adds partition-scoped diagnostics without exposing sensitive payloads [4], tightening what was a safety gap. The team also restored four major doc guides that got lost in a modernization pass: grain call filter patterns with compiled examples [5], DelayDeactivation timing semantics [6], the bare-bones Hello World quickstart [7], and custom placement strategies [8]. Across both repos, 17 commits and 17 PRs shipped in the last 24 hours.

Action items

→ Review the new DynamoDB transaction diagnostics in Orleans to understand failure surfacing for your grain state storage dotnet/orleans [plan]
→ Consult the restored Orleans docs before writing new grain filters or placement logic dotnet/orleans [monitor]
→ Test your haiku or illumos x64 builds against the latest runtime dotnet/runtime [monitor]
