Summary
Provides a base class for sending HTTP requests and receiving HTTP responses from a resource identified over a network.
The HttpClient class is an IDisposable object. It is recommended that you use a single instance of HttpClient for the lifetime of an application. For more information, see HttpClient lifecycle management.
The HttpClient class implements the modern, more performant way of making HTTP requests. It supports asynchronous operations and is designed for extensibility.
Syntax
