I have some user controls in an umbraco 6 instance.

There's the need to put a repository in there and, after installing Autofac, I was expecting the property IRepository automatically injected.

But that's always null.

Here's my register events class that registers the container:

public class RegisterEvents : ApplicationEventHandler
{
    protected override void ApplicationStarted(UmbracoApplicationBase umbracoApplication, ApplicationContext applicationContext)
    {
        ContainerBuilder builder = new ContainerBuilder();

        builder.RegisterType<Logger>().As<ILogger>();
        builder.RegisterType<Repository>().As<IRepository>();

        DependencyResolver.SetResolver(new AutofacDependencyResolver(builder.Build()));
        base.ApplicationStarted(umbracoApplication, applicationContext);
    }
}

If I do:

DependencyResolver.Current.GetService<IEmailRepository>();

The Email public constructor that accepts an ILogger is injected with an instance of the chosen implementation so I can see that the dependency resolver seems to be working fine except with usercontrols...

I tried to implement DI the Umbraco4 way (webforms instead of MVC) but it didn't work.

I am not looking forward to having my usercontrols converted to MVC views as they're somewhat complex and it would take too long to do that.

I didn't want to do service location here but I feel I am stuck here with it. Any suggestions on how to have the properties injected?
