C# Server

This lesson is part of C# · All levels

Summary

C# is not limited to console programs; with the Core, C# became the foundation of web applications and server-side APIs. The server receives a request from the client, processes it, and then sends a response in the form of JSON, HTML, or a file. An asynchronous model with await supports handling many requests efficiently without blocking threads.

Key points

Core is the official web framework for building APIs and sites in C#. (.NET)
The minimal API model allows creating endpoints in only a few rows of code.
Requests contain client data, responses contain server responses in the form of status codes and bodies.
The async and await keywords allow servers to serve multiple clients without blocking threads.
On the console side, HttpClient is often used to test and call the endpoint API.
