Reflectionless, source-generated, thin abstraction layer over the ASP.NET Core Minimal APIs interface.

How to Use

Based on the Vertical Slice Architecture with Feature folder. There is one class for every API endpoint. A basic example looks like the following:

using Microsoft.AspNetCore.Mvc;
using MinimalApiBuilder;

public partial class BasicEndpoint : MinimalApiBuilderEndpoint
    private static string Handle([FromServices] BasicEndpoint endpoint)
        return "Hello, World!";

The endpoint class must be partial, inherit from MinimalApiBuilderEndpoint, and have a static Handle or HandleAsync method with the containing type passed from dependency injection. The endpoint is mapped through the typical IEndpointRouteBuilder Map<Verb> extension methods:


The above is functionally equivalent to:

app.MapGet("/hello", static () => "Hello, World!");

This library depends on FluentValidation >= 11. An endpoint can have a validated request object:

public struct BasicRequest
    public required string Name { get; init; }

public partial class BasicRequestEndpoint : MinimalApiBuilderEndpoint
    private static string Handle([FromServices] BasicRequestEndpoint endpoint,
        [AsParameters] BasicRequest request)
        return $"Hello, {request.Name}!";

public class BasicRequestValidator : AbstractValidator<BasicRequest>
    public BasicRequestValidator()
        RuleFor(static request => request.Name).MinimumLength(2);

The incremental generator will generate code to validate the request object before the handler is called and return a 400 Bad Request response if the validation fails. In Program.cs the below


needs to be added to register the necessary types with dependency injection.


Users can add configuration through entries in .editorconfig or with MSBuild properties. The following options are available:

minimalapibuilder_assign_name_to_endpoint (true | false)

If true, the generator will add a unique public const string Name field to the endpoint classes and call the WithName extension method when mapping them.

minimalapibuilder_assign_name_to_endpoint = true
