maui-data-binding
.NET MAUI Data Binding
Wire UI controls to ViewModel properties with compile-time safety, correct change notification, and minimal overhead. Prefer compiled bindings everywhere and treat binding warnings as build errors.
When to Use
- Adding
x:DataTypecompiled bindings to a new or existing page - Implementing
INotifyPropertyChangedor CommunityToolkitObservableObject - Creating or consuming
IValueConverter/IMultiValueConverter - Choosing the correct
BindingModefor a control property - Setting
BindingContextin XAML or code-behind - Using relative bindings (
Self,AncestorType,TemplatedParent) - Applying
StringFormat,FallbackValue, orTargetNullValue - Writing AOT-safe code bindings with
SetBindingand lambdas (.NET 9+)

537optimizing-ef-core-queries
Optimize Entity Framework Core queries by fixing N+1 problems, choosing correct tracking modes, using compiled queries, and avoiding common performance traps. Use when EF Core queries are slow, generating excessive SQL, or causing high database load.
461csharp-scripts
Run file-based C# apps with the .NET CLI when the user explicitly wants C#/.NET code without creating a project. Use for C# language/API experiments, one-file C# apps, small multi-file C# apps composed with `#:include`/`#:exclude`, or C# file-based apps linked with `#:ref`. Do not use for language-agnostic throwaway scripts, generic computations, Python/PowerShell-style automation, full projects, or existing app integration.

425msbuild-antipatterns
Catalog of MSBuild anti-patterns with detection rules and fix recipes. Only activate in MSBuild/.NET build context. USE FOR: reviewing, auditing, or cleaning up .csproj, .vbproj, .fsproj, .props, .targets, or .proj files. Each anti-pattern has a symptom, explanation, and concrete BAD→GOOD transformation. Covers Exec-instead-of-built-in-task, unquoted conditions, hardcoded paths, restating SDK defaults, scattered package versions, and more. DO NOT USE FOR: non-MSBuild build systems (npm, Maven, CMake, etc.), project migration to SDK-style (use msbuild-modernization).
369msbuild-modernization
Guide for modernizing and migrating MSBuild project files to SDK-style format. Only activate in MSBuild/.NET build context. USE FOR: converting legacy .csproj/.vbproj with verbose XML to SDK-style, migrating packages.config to PackageReference, removing Properties/AssemblyInfo.cs in favor of auto-generation, eliminating explicit <Compile Include> lists via implicit globbing, consolidating shared settings into Directory.Build.props. Indicators of legacy projects: ToolsVersion attribute, <Import Project=\"$(MSBuildToolsPath)\">, .csproj files > 50 lines for simple projects. DO NOT USE FOR: projects already in SDK-style format, non-.NET build systems (npm, Maven, CMake), .NET Framework projects that cannot move to SDK-style. INVOKES: dotnet try-convert, upgrade-assistant tools.
