Zstandard vs Brotli vs Gzip response compression in .NET 11

Zstandard is the right default for dynamic API responses in .NET 11, but not at the quality the ASP.NET Core provider ships with. Benchmarks on real JSON payloads showing why quality 1 beats the default quality 3 on both size and CPU, when Brotli still wins, and why Gzip survives only as a fallback.

2026-08-14 errors flutter android

Fix: An error occurred while preparing SDK package NDK (Side by side): Not in GZIP format

The SDK Manager is re-unpacking a corrupt archive it cached in .downloadIntermediates. Delete that folder and the half-extracted ndk/<version> directory, then re-run the build.

2026-08-14 errors flutter maui

Fix: Google Play rejects a Flutter or .NET MAUI app for missing 16 KB memory page size support

Play rejects the bundle because a 64-bit .so still has 4 KB ELF segments. Find the offending library, rebuild it with NDK r28+, and verify with zipalign -P 16.

2026-08-14 errors flutter dart

Fix: mprotect failed: 13 (Permission denied) in a Flutter iOS debug build

iOS blocks the Dart VM from flipping memory pages to executable, so JIT dies at startup. Upgrade to Flutter 3.35.0 or later for iOS 26, 3.32.0 for iOS 18.4. There is no entitlement that fixes it.

MCP Server Design for a Large Internal API Surface

Mapping 200 internal REST endpoints to 200 MCP tools puts 200 KB of JSON schema in front of every request. The 2026-07-28 spec also made the usual escape hatch illegal: tools/list MUST NOT vary per-connection, so per-session dynamic registration is gone. Here are the three levers that still work, with measured wire sizes and verified code on @modelcontextprotocol/server 2.0.0.

Microsoft.Extensions.AI 10.9 Ships Routing and Failover Chat Clients

Microsoft.Extensions.AI 10.9.0 adds RoutingChatClient, OrderedFailoverChatClient, and SemanticRoutingChatClient. Verified against the real package: what fails over, what does not, and why MEAI001 breaks your build.

Blazor Server Circuits Now Pause Themselves When the Tab Goes Idle

.NET 11 Preview 7 adds an opt-in package that pauses interactive Server circuits when the browser tab is hidden, freeing memory and SignalR connections held by users who are not actually there.

2026-08-13 errors blazor aspnet-core

Fix: 404 Not Found for blazor.server.js after installing a new .NET SDK

blazor.server.js 404s on .NET 10 because the script stopped being an embedded resource. Add RequiresAspNetWebAssets to the host project, or make sure it has a .razor file.

2026-08-13 errors dotnet-maui msbuild

Fix: MSB4057 The target "ResolvePackageAssets" does not exist in the project in .NET MAUI

MSB4057 means a target ran against the outer cross-targeting build of a multi-targeted MAUI project. Pass a TFM, or guard the target with a TargetFramework condition.

2026-08-13 errors dotnet testing

Fix: Visual Studio Test Explorer hangs on an xUnit v3 project while dotnet test passes

Test Explorer drives xUnit v3 through Microsoft.Testing.Platform server mode over a JSON-RPC socket, dotnet test does not. Set UseMicrosoftTestingPlatformRunner so both paths are the same code, or set DisableTestingPlatformServerCapability to fall back to VSTest.
