dotnet Skill

Scaffolds VS Code custom agent files (.agent.md) with YAML frontmatter, tool configuration, handoffs, and instructions for specialized AI personas.

dotnet Skill

Run, filter, or troubleshoot .NET tests with `dotnet test`, detecting the test platform (VSTest vs Microsoft.Testing.Platform) and framework to apply the correct command syntax.

dotnet Skill

Calculates CRAP (Change Risk Anti-Patterns) scores for .NET methods by combining cyclomatic complexity with code coverage data from Cobertura XML reports.

dotnet Skill

Install a .NET SDK into a project-local directory for safe preview testing, version pinning, or reproducible team setups without modifying the system-wide installation.

dotnet Skill

Grades individual test methods and produces a compact markdown table with a letter grade, score band, and one-line note for each test.

dotnet Skill

Analyzes test suites across multiple languages and tags each test with standardized traits (positive, negative, critical-path, etc.) for better test categorization and coverage visibility.

dotnet Bundle

Test C# MCP servers at unit and integration levels using xUnit, Moq, and the MCP client SDK.

dotnet Skill

Reference for test filter syntax across VSTest and MTP platforms, covering MSTest, NUnit, xUnit v3, and TUnit frameworks with examples and translation guidance.

dotnet Bundle

Run, debug, and interactively test C# MCP servers locally with IDE configuration, MCP Inspector, and GitHub Copilot Agent Mode integration.

dotnet Skill

Sets up Microsoft Testing Platform hot reload to iterate fixes on failing tests without rebuilding, covering package installation, environment configuration, and the iterative workflow.

dotnet Bundle

Create MCP servers using the C# SDK and .NET project templates, covering scaffolding, tool/prompt/resource implementation, and transport configuration for stdio and HTTP.

dotnet Bundle

Migrate .NET projects from per-project package versioning to NuGet Central Package Management (CPM) using Directory.Packages.props, with baseline build capture, version conflict resolution, and post-conversion validation.

dotnet Bundle

Publish and deploy C# MCP servers to NuGet, Docker, Azure, and the MCP Registry.

dotnet Skill

Plan complex Blazor UI features by decomposing them into focused, composable components with clear data flow and implementation order.

dotnet Skill

Add, review, or fix JavaScript interop in Blazor components, including collocated modules, lifecycle timing, batching, typed wrappers, and disposal patterns.

dotnet Bundle

Create, run, configure, and review BenchmarkDotNet microbenchmarks for .NET code, covering project setup, comparison strategies, and cost-aware execution.

dotnet Bundle

Wire UI controls to ViewModel properties with compile-time safety, change notification, and minimal overhead using .NET MAUI data bindings.

dotnet Skill

Analyzes test suites to measure assertion diversity, detect shallow or trivial assertions, and identify tests that lack meaningful verification.

dotnet Bundle

Analyzes .NET project code coverage and CRAP (Change Risk Anti-Patterns) scores to identify risk hotspots, methods blocking coverage gains, and prioritize where to add tests.

dotnet Skill

Analyzes production code to find gaps in existing tests by reasoning about hypothetical mutations and checking whether tests would catch them.

dotnet Skill

Run file-based C# apps with the .NET CLI for quick experiments, prototypes, and small utilities without creating a project.

dotnet Bundle

Correctly call native C/C++ libraries from .NET using P/Invoke and LibraryImport, covering function signatures, string marshalling, memory lifetime, SafeHandle, and cross-platform patterns.

dotnet Skill

Guides technology selection and implementation of AI and ML features in .NET 8+ applications using ML.NET, Microsoft.Extensions.AI, Microsoft Agent Framework, GitHub Copilot SDK, ONNX Runtime, and OllamaSharp.

dotnet Bundle

Create or review Blazor components (.razor files) with correct architecture, covering parameters, EventCallback, RenderFragment, lifecycle, async patterns, disposal, and CSS isolation.

dotnet Bundle

Diagnoses and fixes .NET MAUI development environment issues by validating .NET SDK, workloads, Java JDK, Android SDK, Xcode, and Windows SDK with version requirements discovered dynamically from NuGet.

dotnet Bundle

Handle .NET MAUI application state transitions, Window lifecycle events, and state preservation across backgrounding and resume cycles.

dotnet Skill

Provides canonical patterns for MSBuild item groups: Include/Remove/Update semantics, item metadata, batching with %(Metadata), transforms, per-item filtering, and cross-product batching pitfalls.

dotnet Bundle

Generates and writes unit tests for any programming language using a multi-agent pipeline that researches, plans, and implements tests with build and verification steps.

dotnet Skill

Detects the test platform (VSTest vs Microsoft.Testing.Platform) and test framework (MSTest, xUnit, NUnit, TUnit) from .NET project files.

dotnet Skill

Audits test files for anti-patterns and quality issues, producing a severity-ranked report across multiple languages and frameworks.

dotnet Skill

Guides creation and modification of ASP.NET Core Web API endpoints with correct HTTP semantics, OpenAPI metadata, and error handling.

dotnet Bundle

Guidance for implementing CollectionView in .NET MAUI apps — data display, layouts (list & grid), selection, grouping, scrolling, empty views, templates, incremental loading, swipe actions, and pull-to-refresh.

dotnet Skill

Diagnose and improve MSBuild project evaluation performance by analyzing phases, glob patterns, import chains, and property functions.

dotnet Skill

Canonical patterns for writing custom MSBuild targets, covering the three-level target chain, chain extension, DependsOnTargets vs BeforeTargets vs AfterTargets, Returns vs Outputs, and common pitfalls.

dotnet Skill

Provides guidance on new System.Text.Json APIs introduced in .NET 11, including typed JsonTypeInfo access and PascalCase naming policy.
