Original: ASP.NET Core: Building High-Performance Web Applications and APIs

Short summary

ASP.NET Core is a free, cross-platform framework for building high-performance APIs and web apps with modularity and flexible deployment. The guide covers minimal APIs for lightweight microservices, MVC for complex applications, and modern patterns like dependency injection and authentication. Practical code examples demonstrate building production-ready services with features like automatic validation and Swagger documentation.

  • ASP.NET Core offers exceptional performance, modularity, and cross-platform deployment (Windows, Linux, containers)
  • Minimal APIs provide a lightweight approach for microservices and prototypes with automatic binding and parameter inference
  • MVC pattern with [ApiController] attributes enables built-in validation, error handling, and conventions for larger applications
