Could not load type of field 'Toolkit.Samples.Forms.Samples.PopupViewerSample:popupViewer'

[ramtechjoe]

Trying to run the Sample I get an exception when it tries to load a page

Navigation.PushAsync(Activator.CreateInstance(sample.Page) as Page);

System.TypeLoadException Message=Could not load type of field 'Toolkit.Samples.Forms.Samples.PopupViewerSample:popupViewer' (1) due to: Could not load file or assembly 'Esri.ArcGISRuntime.Toolkit.Xamarin.Forms, Version=100.5.0.0, Culture=neutral, PublicKeyToken=null' or one of its dependencies.

I have made some changes to strip the code down to just the iOS version with a .net standard target (mainly because I could never get it to compile with the the different targets set)
