A protocol-invalid duplicate stream ID could leave the displaced hub argument permanently unreachable, and now it's rejected immediately.
SignalR upload streams were registered with dictionary assignment, so a protocol-invalid duplicate stream ID replaced the active channel and could leave the displaced hub argument permanently unreachable [1]. The fix makes registration atomic and rejects an active duplicate immediately, while preserving valid multi-stream uploads and reuse after completion [1]. Meanwhile, ASP.NET Core tightened sign-in behavior: Identity UI and Blazor templates now honor all configured confirmation requirements after registration, so users requiring confirmed email or phone are redirected to registration confirmation instead of being signed in automatically [2]. This is a breaking change if you relied on automatic sign-in, but you can restore it by disabling the relevant requirements [2]. Over in Blazor, the new Components.AI client tool rendering layer adds browser-owned tool execution to the chat foundation and lights up the canonical Agentic Chat change_background action [3]. Roslyn adds a TypeLayout API to address issue 76928 [4], and avoids reordering by-ref locals to fix issue 84733 [5]. On the Android side, universal APK generation becomes incremental, and release assembly store compression jumps to maximum Zstandard level 22 for optimized builds [6][7]. The dotnet/dotnet repo pulls in codeflow updates from aspnetcore, nuget.client, vstest, and fsharp [8][9][10][11].
