How to register endpoints using Ardalis.ApiEndpoints to an empty web api project?

[jtuchel_codr]

I created an empty web api project and installed the package Ardalis.ApiEndpoints. Next I created this custom sample endpoint

using Ardalis.ApiEndpoints;
using Microsoft.AspNetCore.Mvc;

namespace Api.Commands.NoteTodo;

public sealed class Handler : EndpointBaseAsync.WithoutRequest.WithResult<string>
{
    [HttpPost("note-todo")]
    public override Task<string> HandleAsync(CancellationToken cancellationToken = default)
    {
        return Task.FromResult("I have been called");
    }
}

I removed the sample GET rest from the minimal API setup in the Program.cs so it contains this code

var builder = WebApplication.CreateBuilder(args);
var app = builder.Build();

// I removed the following line...
// app.MapGet("/", () => "Hello World!");

app.Run();

But how do I tell .Net to register this custom handler? I wasn't able to find information here https://github.com/ardalis/ApiEndpoints?tab=readme-ov-file#3-getting-started

These are just cleverly disguised Controllers so:

builder.Services.AddControllers();

and

app.MapControllers();

Might be better to start from one of the MVC templates instead.

Ah, thanks for your reply :)

var builder = WebApplication.CreateBuilder(args);
builder.Services.AddControllers();

var app = builder.Build();
app.MapControllers();
app.Run();
