In .NET 8, Microsoft pushed Minimal APIs to a new level. You can now build fully functional REST APIs without a single Controller class. Using app.MapGet(), app.MapPost() with route groups, filters, and typed results — your API becomes lean and lightning fast. Minimal APIs have lower overhead than MVC, making them ideal for microservices. Features like RouteGroupBuilder, IEndpointFilter, and TypedResults make them production-grade. Most developers don't know you can even add middleware, validation, and versioning — all without controllers!
