This happens in your samples using the Windows Machine option to launch the app. In your samples, it does a really good job of translating the voice and putting it in the textbox but ultimately crashes with unhandled exceptions and VS.NET tries to bring up its own debugger.
I found the documentation where it mentions this is going to happen on windows. In Android, it works just fine. I don't intend to support Windows in production. Hopefully, this can get resolved but not mission critical.
