This is an error in your own code. There's just a lot of mess here... and I'm not sure what you're trying to accomplish but I am betting that if you're passing around the DI container you need to re-evaluate your architecture. While this is indeed sometimes necessary it is much more the exception that you should be using the DI container directly. Remember that you can do things like inject Lazy<T> or Func<T> by default with Prism.

Bottom line though if you new up another instance of your Tool and then don't set the IContainerProvider you shouldn't be surprised when you get a NullReferenceException.

Thanks for comments. I think I didn't reproduce the original problem. Sorry for wasting your time.
