I'm developing an app which uses a Master-Detail page among other things. Everything is fine on iOS and Android using Xamarin.Forms version 1.3.0.6292. On WinPhone I get an exception when the Master-Detail is opened (to be exact, when a list view is created in the detail page):
A first chance exception of type 'System.InvalidOperationException' occurred in Xamarin.Forms.Core.DLL
If I switch to Xamarin.Forms version 1.2.3.6257 for the WinPhone app, I do not get this exception.
Do you have an idea what causes this or have you experienced the same behaviour?
