WPF - How do I expose namespaces throughout a project

Question

Sorry... I hope this isnt a really dumb question... but I couldnt find the answer anywhere. I have a WPF application, in each of my usercontrols / windows I am currently putting the following code in xaml in the header...

xmlns:properties="clr-namespace:MaxCut2.Properties"

This particular properties namespace I use in every window / usercontrol in my project and I would have thought that if I had put the code in my App.xaml, it would have been exposed to all the child windows/uc's - but it doesn't seem to work.

Is there a way that I can expose this without having to declare it in every file in XAML?

If you're certain that the content of your class will never conflict with the standard WPF namespaces, you could use

[assembly: XmlnsDefinition("http://schemas.microsoft.com/winfx/2006/xaml/presentation", "MaxCut2.Properties")]

to include your class in the default namespace. But I wouldn't recommend it - as mentioned there's the potential for conflicts and it could make your code harder to maintain.
