Transient instances created by lambda functions are not properly registered for disposal

[CodingGorilla]

This creates a unit test which demonstrates that when a lambda function is used to generate an instance with a transient lifetime, that instance is created in a dependent class' constructor function but never registered for disposal in the containing scope.

My proposed solution is to add some generated code that attempts to cast the constructed instance to IDisposable and if it casts, then add it to the scope's Disposables collection during construction of the depending instance.

This is a bit hacky and I'm not sure it's the best solution, but it does solve the problem.
