Property Injection using Autofac

Question

So I have a simple question (I think).

How do you do Property Injection on a FilterAttribute with Autofac?

Public Class TestFilterAttribute
    Inherits ActionFilterAttribute

    Public Property Service As IMyService        

    Public Overrides Sub OnActionExecuting(filterContext As System.Web.Mvc.ActionExecutingContext)

        ** I need to get to the IMyService here **
        Dim val = Service.GetValue()

        MyBase.OnActionExecuting(filterContext)
    End Sub
End Class

I have registered the service in the container:

builder.RegisterType(Of MyService).As(Of IMyService)().InstancePerHttpRequest()

Or maybe I am going about it the wrong way. I want to be able to inject filter attributes.

Also, when using Register, do you have to do .As as well? Like in RegisterType.

Make sure that you call the RegisterFilterProvider method on the container builder and it will take care of the rest.
