ASP.NET Core Minimal API's Endpoints registration helper

Extensions.cs

// Endpoints registration helper

// Enables DI for a group of endpoints to reduce init code and repeating parameters across endpoints

// Usage in e.g. Program.cs:

app.RegisterEndpoints(
    typeof(CatalogEndpoints),
    typeof(BasketsEndpoints)
);


// Implementation:

public interface IEndpoints
{
    void Register(IEndpointRouteBuilder routeBuilder);
}

public static class WebApplicationExtensions
{
    public static void RegisterEndpoints(this WebApplication app, params Type[] endpointsTypes)
    {
        foreach (var endpointsType in endpointsTypes)
        {
            ((IEndpoints)ActivatorUtilities.CreateInstance(app.Services, endpointsType))
            .Register(app);
        }
    }
}
