Can someone give me some guidance on setting up and using DNN's dependency injection? 

As far as I understand there ComponentModel.ComponentFactory class to be used for this purpose, but I am unable to find a good source on usage. I am using Asp.Net WebForms and DNN 7.4. I am using the DAL DNN Module Template.

1) How do I use it?

2) Where do I register my classes?

3) How can I choose my instance lifetime?

4) How do I can dependencies?

5) Are there any tutorials or documentation?

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)

Clarification on #4: How do I "chain" dependencies? How can I use the container to provide dependencies to other dependencies in the container? e.g. ClassA(), ClassB(IClassA A), ClassC(IClassB B), etc...

Hi I use Autofac for Dependency injection with DNN (7.4+)
I use ChrisHammond Template.
https://github.com/ChrisHammond/DNNTe...

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
