//The XAML designer process (XDesProc.exe) is configured, by default, to populate its ViewModel in the designer UI. This creates a copy of the model--which creates a second

//the exception is thrown.
//To fix this, disable the following option in the Visual Studio toolbar above:
// Tools -> Options -> XAML Designer -> "Run project code in XAML Designer (if supported)"
//Once that's disabled, restart Visual Studio. Problem solved.
