End-to-end dark mode in .NET MAUI 11: AppThemeBinding, SetAppThemeColor, RequestedTheme, UserAppTheme override with persistence, the RequestedThemeChanged event, and the per-platform Info.plist and MainActivity bits that the docs gloss over.

A complete .NET 11 setup for Tailwind CSS v4 in a Blazor WebAssembly app: standalone CLI (no Node), MSBuild target, @source directives for Razor and CSS isolation files, and a publish pipeline that survives Native AOT.

A practical guide to spotting N+1 queries in EF Core 11: what the pattern looks like in real code, how to surface it via logging, diagnostic interceptors, OpenTelemetry, and a test that fails the build when a hot path regresses.

A practical guide to EF Core 11 compiled queries: when EF.CompileAsyncQuery actually wins, the static-field pattern, the Include and tracking gotchas, and how to benchmark before and after so you can prove it was worth the extra ceremony.

Strip Android and iOS from a .NET MAUI 11 project so it ships Windows and Mac Catalyst only: the csproj edits, the workload commands, and the multi-targeting that keeps your code clean.

Take an existing Semantic Kernel plugin with [KernelFunction] methods and turn it into a Model Context Protocol server other agents can call. Covers the drop-in WithTools(kernel) bridge, the native [McpServerTool] rewrite, parameter binding, dependency injection, and the gotchas that bite during the cutover.

Wire OpenTelemetry traces, metrics, and logs into a .NET 11 ASP.NET Core app with the OTLP exporter, then ship them to a free, self-hosted backend: the standalone Aspire Dashboard for local dev, Jaeger and SigNoz for self-hosted production, and the OpenTelemetry Collector when you need both.

A complete guide to running ASP.NET Core integration tests against a real SQL Server 2022 using Testcontainers 4.11 and EF Core 11: WebApplicationFactory wiring, IAsyncLifetime, swapping the DbContext registration, applying migrations, parallelism, Ryuk cleanup, and CI gotchas.
