## What it is
A C# library providing base classes for organizing ASP.NET Core web APIs around one endpoint per class (the REPR pattern) instead of traditional controllers. It is distributed as the Ardalis.ApiEndpoints NuGet package.

## Use cases
- organize asp.net core api endpoints one class per endpoint
- replace controllers with single-action endpoint classes in dotnet
- implement the repr pattern in web apis
- structure large asp.net core web api codebases
- learn endpoint-per-class api design in c#

## When to choose
- you're on ASP.NET Core with MVC controllers and want one-file-per-endpoint organization
- you want a lightweight, well-known base class approach to API endpoints in .NET

## When to avoid
- you're on .NET 6+ and can use Minimal APIs instead
- you want a richer, faster endpoint framework - the author recommends FastEndpoints
- you're not building ASP.NET Core web APIs
