Hello - I have been moving my Alexa skill away from my own custom .NET "plumbing" code and have found your library very easy to work with so far.
My only wish would be for OnLaunch to automatically add a breadcrumb to Session.IntentSequence. There of course other ways I am able to determine if a skill has been interacted with via OnLaunch, but I would love to have something as elegant as simply having it in IntentSequence :)
