Please forgive my typo, #4 should be:

How do I register my chained dependencies?

e.g. Dependencies with dependencies
ClassA
ClassB(IClassA a)
ClassC(IClassB C)

Hi I use Autofac for Dependency injection with DNN (7.4+)
I use ChrisHammond Template.

You need to manually Install Autofac and WebActivatorEx from Nuget


[assembly: WebActivatorEx.PreApplicationStartMethod(typeof(purplecs.Modules.MedulawPodcast.Bindings), "RegisterServices")]
namespace purplecs.Modules.MedulawPodcast
{
public class Bindings
{//
public static IContainer Container { get; set; }

public static void RegisterServices()
{
var builder = new ContainerBuilder();

builder.RegisterAssemblyTypes(Assembly.GetExecutingAssembly())
.Where((x) => x.Name.EndsWith("Repository"))
.AsSelf();

Container = builder.Build();

}
}
}

I use the above Code to Registering My business logic Classes.

I also create a base Class for Portal Module Base

public classTModuleBase : PortalModuleBase
{

public TModuleBase()
{

Bindings.Container.InjectUnsetProperties(this);
// CheckSettings();

}

}

I my ascx file I Inherit my TModuleBase

public partial class TascxClass: TModuleBase
{
public TRepository tRepo {get;set;}
}

I use Property Injection method to inject the objects.

I suppose the same approach can be used for A MVC application too



Hope this helps
