Android NativeAOT apps can now properly export crypto JNI callbacks, while the runtime team shipped outerloop CI coverage for wasm/CoreCLR to finally catch slow suite regressions.

The Android fix [1] resolves a critical packaging gap where the crypto trust-manager JNI callback wasn't being retained in final APK binaries, unblocking customer NativeAOT deployments on mobile. That same team simultaneously shipped wasm/CoreCLR outerloop CI [2], which runs the full slow test suites on single-threaded wasm for the first time, catching regressions that desktop and Mono browser builds miss. On the API front, Process.Start gained platform-specific callback overloads [3] letting callers inject custom Windows and Unix process creation logic while staying within Process infrastructure for stream handling and lifecycle management. The reflection-based XmlSerializer now handles XmlSchemaObject-derived types correctly [4] by matching IL-reader behavior on schema name encoding. WinForms shipped a ToolStripScrollDownButton fix [5] that prevents exceptions when the last item is visible, and fixed NumericUpDown button rendering [6] when visual styles are disabled. The monorepo continues ingesting from runtime, efcore, SDK, and F# [7] [8] [9] [10].

Action items

→ If shipping Android NativeAOT apps, verify crypto JNI exports are retained in final APK after patching dotnet/runtime [immediate]
→ Monitor wasm/CoreCLR outerloop results for slow test suite regressions in your dependencies dotnet/runtime [monitor]
→ Update WinForms if ToolStripScrollDownButton exceptions appear in dropdown menus dotnet/winforms [plan]
