Bug Example Project

This may be a re-opening of https://bugzilla.xamarin.com/show_bug.cgi?id=40740, but that may have had a different fix.

1.) Open Sample Project (notice target is set to 15063 and min version is 10586, which is the default in 2017 when you create a new UWP project)
2.) Run sample
3.) Exception thrown in constructor of Forms App
System.TypeLoadException: 'Could not find Windows Runtime type 'Windows.UI.ViewManagement.StatusBar'.'


Target older versions of UWP

Hey James, I'm not seeing the crash when running the sample project or with a new project. It launched successfully on both a Mobile v15063 and v14393 emulator and the desktop. 

The last comment in that old bug mentioned that in their case it was not related to Xamarin. Can you try if a non-Forms UWP project with the same target also crashes for you?

I tried this again with VS2017 15.3 and I still did not experience the exception mentioned, so this may indicate an issue with the VS or UWP SDK install on the machine instead.
