HTTP/3 is the third and upcoming major version of HTTP.

HTTP/3 uses the same semantics as HTTP/1.1 and HTTP/2 but instead of using TCP as the transport layer for the session, it uses QUIC, a new Internet transport protocol.

HTTP/3 and QUIC have a number of benefits including native multiplexing, 0-RTT support, and increased security.

In this session, we will learn how to enable HTTP/3 in a .NET 6 application which is served by Kestrel.
