SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires Microsoft.AspNetCore.OpenApi.

What problem does it solve?

This Skill simplifies the creation of HTTP APIs in ASP.NET Core .NET 10 by guiding users through Minimal APIs, reducing boilerplate and accelerating development for microservices and simple REST endpoints.

Core Features & Use Cases

  • Simplified API Development: Create HTTP APIs with minimal code, no controllers, and inline endpoint definitions.
  • OpenAPI/Swagger Integration: Automatically generate API documentation for discoverability and testing.
  • Structured Endpoints: Organize APIs using route groups and leverage flexible parameter binding.
  • Use Case: When building a new microservice or a lightweight backend for a frontend application, use this skill to quickly set up a performant and well-documented API.

Quick Start

FAQPage Schema
How do I build a REST API without controllers in ASP.NET Core?

Minimal APIs let you define HTTP endpoints inline using lambda expressions without controller classes. You map routes directly in your Program.cs file, reducing boilerplate and setup overhead for simple or microservice APIs.

Can I generate OpenAPI documentation automatically for my .NET API?

Yes. Minimal APIs integrate with OpenAPI/Swagger to automatically generate API documentation. Add metadata annotations to your endpoints and the documentation is discoverable and testable immediately.

What's the best way to organize endpoints in a Minimal API?

Use route groups to logically organize related endpoints, apply shared configuration like authentication, and reduce repetition. This keeps your API structured and maintainable as it grows.

Do Minimal APIs support dependency injection in ASP.NET Core?

Yes. Minimal APIs fully support dependency injection. You inject services directly into endpoint handlers as parameters, keeping your endpoints clean and testable.

When should I use Minimal APIs instead of controller-based APIs?

Minimal APIs excel for microservices, lightweight backends, prototypes, and cloud-native applications where minimal code and fast startup matter. Use them when you need simple HTTP endpoints without the overhead of controller classes.

How do I bind and validate parameters in a Minimal API endpoint?

Minimal APIs support flexible parameter binding from query strings, route segments, headers, and request bodies. The framework automatically maps and validates typed parameters, reducing manual parsing.
