## What it does

This skill guides Claude Code on ASP.NET Core API work, from Minimal APIs and controllers to input validation and error handling. It covers EF Core data access, migration setup and query patterns, plus authentication and authorization.

Background task examples use `IHostedService`, `BackgroundService`, and schedulers such as Hangfire or Quartz.NET. The material also includes patterns for JWT, SignalR, and tests. Its examples rely on specific libraries and storage options, so check that the technologies you want match the ones in your project.
