dotnet-claude-kit is an opinionated Claude Code plugin that transforms the AI assistant into an expert .NET 10 developer. It provides 47 skills (knowledge + workflow orchestrators), 10 specialist agents (e.g., dotnet-architect, ef-core-specialist), 10 always-loaded rules, 5 project templates, automation hooks, and a Roslyn-based MCP server (CWM.RoslynNavigator) offering 22 read-only code analysis tools. The MCP server delivers token-efficient semantic queries (symbol resolution, anti-pattern detection, dead code analysis, dependency graphs) via stdio, replacing expensive file reads. The architecture is modular: skills are markdown files loaded on demand, agents route requests to specialists, and the MCP server provides a robust program analysis backend. The system supports multiple AI coding tools (Claude Code, Cursor, Codex CLI, OpenCode) with cross-tool rule parity validation. Its core philosophy emphasizes guided over prescriptive development, modern .NET only (.NET 10/C# 14), and token-conscious interactions. The codebase demonstrates strong engineering with clean abstractions, extensive unit tests (200+ tests), CI/CD for NuGet publishing, and well-documented ADRs. The MCP server components (WorkspaceManager, SymbolResolver, anti-pattern detectors, pagination) are highly reusable and exhibit non-obvious craftsmanship. While the large skill surface requires synchronization, the overall quality is excellent for a developer tooling project.

This repository is a comprehensive educational course titled '.NET Web API Zero to Hero' by codewithmukesh. It contains over 50 independent ASP.NET Core Web API sample projects organized into modules covering fundamentals (minimal APIs, exception handling, logging), database management with EF Core (CRUD, migrations, interceptors, soft deletes, bulk operations, pagination), advanced API patterns (CQRS with MediatR, custom dispatcher, Result pattern, mapping benchmarks), performance and caching (in-memory, Redis, HybridCache, EF second-level cache), API security (JWT, refresh tokens, role/claims/policy/permission-based authorization, API keys, CORS, rate limiting), file handling (PDF invoice generation), architecture (Clean Architecture vs Vertical Slice), observability (health checks, structured logging), and background processing. Each sample is a self-contained, runnable project with minimal setup (often using in-memory databases) and includes extensive BenchmarkDotNet performance comparisons. The code is well-structured, follows modern .NET 10 patterns, and demonstrates production-quality implementations of cross-cutting concerns like global exception handling, validation pipelines, and caching strategies. While the repo is primarily a teaching resource, many components (custom CQRS dispatcher, Result pattern, EF Core interceptors, permission-based authorization) are genuinely reusable in other projects.
