How to make the .net HttpClient use http 2.0?

Starting from .NET 5, the HttpClient class supports HTTP/2 by default. To use HTTP/2 with HttpClient in .NET 5 or later, you don't need to do anything special. The HttpClient class will automatically use HTTP/2 if the server supports it.

Here's an example of how to create an instance of HttpClient that uses HTTP/2:

using System.Net.Http;

var httpClient = new HttpClient();

By default, the HttpClient instance will use HTTP/2 if the server supports it. You can also explicitly specify the version of HTTP to use by setting the DefaultRequestVersion property of the HttpClient instance:

using System.Net.Http;

var httpClient = new HttpClient();
httpClient.DefaultRequestVersion = new Version(2, 0);

In this example, we create an instance of HttpClient and set the DefaultRequestVersion property to new Version(2, 0) to explicitly specify that we want to use HTTP/2.

Note that HTTP/2 support is only available in .NET 5 and later. If you are using an earlier version of .NET, you will not be able to use HTTP/2 with HttpClient.
