How do I create a base page in WPF?

Question

I have decided that all my WPF pages need to register a routed event. Rather than include

public static readonly RoutedEvent MyEvent= EventManager.RegisterR

Here's how I've done this in my current project.

First I've defined a class (as @Daren Thomas said - just a plain old C# class, no associated XAML file), like this (and yes, this is a real class - best not to ask):

public class PigFinderPage : Page
{
    /* add custom events and properties here */
}

Then I create a new Page and change its XAML declaration to this:

So I declare it as a PigFinderPage in the "my" namespace. Any page-wide resources you need have to be declared using a similar syntax:

Lastly, switch to the code-behind for this new page, and change its class declaration so that it derives from your custom class rather than directly from Page, like this:

public partial class EarmarkSearchPage : PigFinderPage

Remember to keep it as a partial class.

That's working a treat for me - I can define a bunch of custom properties and events back in "PigFinderPage" and use them in all the descendants.
