FastEndpoints

A light-weight REST Api framework for ASP.Net 6 that implements REPR (Request-Endpoint-Response) Pattern.

FastEndpoints offers a better alternative than the Minimal Api and MVC Controllers with the aim of increasing developer productivity. Performance is on par with the Minimal Api and is faster; uses less memory; and does around 45k more requests per second than a MVC Controller in a head-to-head comparison.
