How do I figure out a “DependencyProperty.UserValue” exception in my WPF/MVVM application?
I have a C#/.Net/WPF/MVVM application.
The application runs fine when running through VS 2015.
When I run the application standalone (on a different machine), I get the following exception at startup:
An unhandled exception of type "System.InvalidOperationEx
ception" occurred in WindowsBase.dll
Additional information "{DependencyProperty.Unser
Value} is not a valid value for property "TopLevelItemTemplateKey"
What is really going on?
How do I debug this?
Thanks
