Autofac - what is MvcApplication

Question

I'm attempting to implement Autofac (first time implementing) into an ASP.NET MVC 4.5 application and the second line of code in this example already has me stumped.

http://docs.autofac.org/en/latest/integration/mvc.html#quick-start

I'm in the Startup.cs class and configuration manager. I can't get it to recognize MvcApplication? Is that a pseudo for something? It has been in every example I can find. Did I miss a reference?

Thanks in advance.

Answer 1

The example is based on the default Visual Studio MVC template(s), which create a Global.asax.cs file with the following class:

public class MvcApplication : System.Web.HttpApplication
{
    protected void Application_Start()
    {
        AreaRegistration.RegisterAllAreas();

        WebApiConfig.Register(GlobalConfiguration.Configuration);
        FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters);
        RouteConfig.RegisterRoutes(RouteTable.Routes);
        BundleConfig.RegisterBundles(BundleTable.Bundles);
        AuthConfig.RegisterAuth();
    }
}

Technically, you don't need this class - you can move everthing to Startup.cs and delete it. The reference to the class is just to get a reference to the MVC assembly, so you can technically use any type in your MVC project (such as the Startup class).

You are surely using asp.net Core and MVC6. If that's correct, then you don't need AutoFac; Dependency Injection is built-in by default.
