Description Marius Stein 2017-06-14 12:32:59 UTC
When trying to run a project the Xamarin live player first compiles without problems and then switches into debug mode. shortly after that the debug mode stops without the app being deployed to the phone. I got the following error in the debugger console:

Der Objektverweis wurde nicht auf eine Objektinstanz festgelegt.
(The object reference is not set to an instance of an object)

Here is an excerpt from my log files:
