Remove non serialisable object in Properties #39

Open benCd opened 5 years ago

benCd commented 5 years ago

A non serialisable object (namely System.Collections.SortedList+SyncSortedList) is currently saved in the system properties, which is causing a bunch of issues.

Stacktrace: Xamarin.Forms PropertyStore: Exception while writing Application properties: System.Runtime.Serialization.SerializationException: Type 'System.Collections.SortedList+SyncSortedList' with data contract name 'SortedList.SyncSortedList:http://schemas.datacontract.org/2004/07/System.Collections' is not expected.
