Migrate legacy .NET project files to SDK-style format, reducing repetitive XML and explicit file lists. Convert package references, move assembly metadata into project settings, and consolidate shared build and package settings across multiple projects.
Upgrade MSTest v3 test projects to v4 by updating packages, adapting code to changed APIs, and checking execution behavior. It also helps resolve build errors and problems finding tests in CI after an upgrade.
Interpret .NET coverage reports, which show code exercised by tests, to explain missing coverage and stalled progress. Calculate the gains needed to reach a target and, when requested, combine coverage with complexity to rank risk.
Provide reference syntax for selecting .NET tests by name, class, category, or other properties. Help test-running skills construct filters for VSTest and Microsoft Testing Platform, or translate existing filters for a different test framework.
Replace C# static calls for time, files, or environment values with existing abstractions that tests can substitute. Update construction and affected tests within a defined scope, while preserving read counts, evaluation order, date-time semantics, and existing static callers.
Set up a persistent Microsoft Testing Platform console host that applies code edits and automatically reruns tests. It covers package setup, test selection, and restarting the host when an edit cannot be applied while running.
Create a missing .NET test project or repair references and solution registration in an existing one. Follow the repository’s framework and package conventions, then verify the build or test entry point used by CI, the automated integration process.
Find changes in observable behavior that existing tests could miss. Map public results to test assertions, identify gaps in boundaries, permissions, and calculations, and propose focused tests, with optional verification when requested.
Classify existing tests with standard tags for success cases, errors, boundaries, and other behaviors. Get a per-test mapping and distribution summary, or apply tags using supported framework syntax and verify compilation and test discovery.
Identify a .NET project’s test framework, project format, and execution platform: VSTest or Microsoft.Testing.Platform. Trace configuration imports and overrides to explain the result, including conflicting settings or differences between target frameworks.
Diagnose and fix MSBuild property problems, including overwritten settings, ineffective conditions, and environment-dependent paths. Review defaults, list appending, and evaluation order so project files and shared build settings retain the intended values.
Migrate .NET Framework code that forcibly stops threads to cooperative cancellation, where work checks and responds to stop requests. The skill covers loops, timeouts, blocked threads, and ASP.NET request endings, with cleanup and validation guidance.
Refactor C#/.NET code through renaming, extraction, consolidation, and other structural changes while preserving behavior. Check compatibility beyond code references, including public APIs and serialized names, then validate with builds and relevant tests.
Configure automatic crash dumps, files that capture application state, or collect one from a running modern .NET process. Follow platform and runtime guidance for desktop, server, Docker, or Kubernetes environments and receive the saved file location.
Run small C# apps without creating a project, using the .NET CLI, its command-line tool. Use it to test language features, explore APIs, or prototype utilities with helper files and NuGet packages.
Convert an older Blazor Server app into a .NET 8+ Blazor Web App while preserving interactive server behavior. It guides changes to page structure, startup configuration, authentication state sharing, and validation of the converted app.
Add light and dark modes or custom color themes to .NET MAUI apps. Covers following system settings, switching themes while the app runs, and saving each user's preferred theme.
Adjust .NET MAUI layouts to avoid system bars, screen cutouts, and keyboards, or extend content to screen edges. It covers .NET 10 safe area APIs, migration from older settings, and CSS coordination for Blazor Hybrid.
Review C#/.NET code for about 50 inefficient API usage patterns across asynchronous work, memory, strings, collections, and I/O. Get exact occurrence counts, prioritized findings, and concrete fixes, with attention to frequently executed code.
Investigate .NET app crashes on Apple platforms by converting runtime addresses in .ips logs into function names, source files, and line numbers. It locates matching debug symbols and supports retrieving logs from connected iOS devices.
Design, configure, run, and review BenchmarkDotNet measurements of small .NET operations. Compare implementations, runtime versions, or input sizes, while controlling setup work, measurement errors, and case counts so results support a concrete performance decision.
Diagnose and fix .NET MAUI development environment problems involving SDKs, Java, Android tools, and platform requirements. The skill discovers required versions from NuGet metadata and checks the environment again after each fix.
Plan initialization, state saving, restoration, and cleanup around .NET MAUI app lifecycle events. Understand how Window events map to each platform, distinguish lost focus from backgrounding, and account for multiple windows.
Build scrollable lists and grids in .NET MAUI using CollectionView. The guidance covers item layouts, selection, grouping, refresh gestures, incremental loading, swipe actions, and empty states, with examples and checks for common implementation mistakes.
