ASP.NET Core & Web: Technologies

ASP.NET Core is one of the fastest mainstream web frameworks. It powers everything from small APIs to some of the largest services on the internet. This category walks through its architecture, from Kestrel and the middleware pipeline to endpoint routing, and then covers each major way to build on it.

You will find complete guides to Minimal APIs, REST API design, Blazor render modes, real-time communication with SignalR, high-performance gRPC services, server-rendered Razor Pages and MVC, OpenAPI documentation, output caching and rate limiting, and building gateways with YARP.
