WPF's migration to /clr:NetCore broke self-contained deployments by misplacing a critical native dependency, while the SDK is collapsing duplicate CLI parsing logic into a single unified implementation.

The WPF team shipped a fix [1] for a build regression introduced by the /clr:pure to /clr:NetCore migration. After DirectWriteForwarder and System.Printing became mixed-mode assemblies, ijwhost.dll was being placed in the managed lib/ folder where RuntimeList.xml couldn't find it, leaving self-contained publishes broken. The fix properly packages ijwhost.dll as a native asset where the runtime expects it. Over in SDK, a major refactor is underway [2] to unify the managed CLI parser (dotnet.dll) and NativeAOT bridge (dotnet-aot.dll) into a single shared implementation, eliminating a massive conditional compilation block that was maintaining two almost-entirely-different Parser classes. On the operational side, the SDK team cleaned up workflow labeling [3] by exempting vseanreesermsft from the servicing-consider label since that account handles internal-to-public flow PRs, and removed the legacy dnx shim from Linux SDK packages [4]. The dotnet/skills repo added JSON output to skill-validator [6] for machine-readable validation reports, and pinned agentic workflow actions to commit SHAs [5] to comply with GitHub org policy that bans mutable tag references at runtime.

Action items

→ Review WPF ijwhost.dll packaging fix if you maintain self-contained publish workflows dotnet/wpf [plan]
→ Watch the SDK CLI parser unification PR for implications on your build scripts dotnet/sdk [monitor]
→ Update any agentic workflow uses to reference pinned SHAs instead of tags dotnet/skills [plan]
