Hi,
thanks for sharing your implementation, great :).
While integrating this in our good old Web Forms stuff i am facing a problem.
I assume is has to do with the AspNetControlLifecyclePolicy

  public class AspNetControlLifecyclePolicy : IInstancePolicy {
    public void Apply(Type pluginType, Instance instance) {
      /*
       * The lifecycle for each control should always be unique. The default
       * namespace for pages and user controls compiled by the ASP.NET
       * runtime is 'ASP'.
       */

      if((instance.ReturnedType.Namespace ?? "").StartsWith("ASP")) {
        instance.SetLifecycleTo(new UniquePerRequestLifecycle());
      }
    }
}

What was the motivation for the "StartsWith("ASP")"?
If I just want to enable the lifecycle for controls, how about this:

 if (typeof(Control).IsAssignableFrom(instance.ReturnedType))
                instance.SetLifecycleTo((ILifecycle) new UniquePerRequestLifecycle());

This would work for me.
Background is an exception in an ascx (I do not want to harass you with that) at Render-stage, with happens at an <%= %> tag. Without the <%= %> tags there is no exception.
`Error Message: Specified argument was out of the range of valid values.

When I implement this solution on a ASP.NET WebForms page that has a required field validator, I am receiving a runtime error that says the runtime is unable to find a control id that is used by the required field validator attribute ControlToValidate.

When I remove this solution (by commenting it out in the Global.asax code behind) this error goes away. Any ideas why this is occurring and what can be done to resolve it?
