ASP.NET Minimal APIs Made Easy...

FastEndpoints is a developer friendly alternative to Minimal APIs & MVC

It nudges you towards the REPR Design Pattern (Request-Endpoint-Response) for convenient & maintainable endpoint creation with virtually no boilerplate.

Performance is on par with Minimal APIs and does noticeably better than MVC Controllers in synthetic benchmarks.
