How to extend service collection of application project to web api in ASP.NET Core 6?-CodePudding

I create new ASP.NET Core 6 solution for a Web API with onion architecture, I just found it, in .NET 6, there is change about dependency injection.

This is my solution structure:

Solution
|- Application
|- Domain
|- Infrastructure
|- API

In Application project, I create this code for dependency injection:

namespace Application
{
    public static class DependencyInjection
    {
        public static void AddApplication(this IServiceCollection services)
        {
            services.AddMediatR(Assembly.GetExecutingAssembly());
        }
    }
}

After that I added Application project as dependency in application.

In previous versions of .NET Core, I can add this to Startup.cs like this services.AddApplication();, but in new .NET 6, I can not find Startup.cs and when I google it, .NET 6 has a different way to use dependency injection.

I already try add code in Program.cs

var builder = WebApplication.CreateBuilder(args);

// Add services to the container.
builder.Services.AddAuthentication(JwtBearerDefaults.AuthenticationScheme)
    .AddMicrosoftIdentityWebApi(builder.Configuration.GetSection("AzureAd"));

builder.Services.AddApplication();  <--- this one

builder.Services.AddControllers();

but it got error

IServiceCollection does not contain AddApplication()

Please help me how to add dependency collection in .NET 6 properly.

Add Application as project reference to your Api project and it should resolve itself. And in using statements add using Application;
