I learned that WPF doesn't support inheritance for classes created with XAML and the associated code behind. Is there a workaround? For instance, I have an app that is a WPF window that contains methods that I would like available in a derived class defined in a mixed mode assembly written in C++/CLI.

Anyone care to take a shot at a suggestion?

Thanks in advance

As you already seem to know you have to separate the XAML from the code behind, you do that be creating a class like any other normal class and inherit from a Control, like Window then in order to alter the appearance and add stuff you have to create a Style.
The below article shows you how you can do it.

Thanks for responding. I'm not sure if what you're suggesting solves the problem. The issue is not exactly visual inheritance. What I've tried is this: I defined a base class (no partials). I then in XAML create the control (a window in this case) derived from the base class. I target the window as a Class Library DLL so I can launch it from a C++ / CLI executable. The class is the C++ class derives from the base class also. At runtime I get the exception: The component 'MyInheritedForm' does not have a resource identified by the URI '/WPFNameSpce;component/mainwindow.xaml'.

I hope that is clearer.

Thanks again
