Refining the removal of strings from WPF dependency properties

Following on from the previous post regarding removing the strings when registering Dependency Properties I wanted to fine tune it so we could remove the need for specifying the type we are defining the dependency properties on.

The way to do this is to cache a static instance of the DependencyPropertyHelper class in our class like so:

private static readonly DependencyPropertyHelper DependencyProperty = new DepenencyPropertyHelper<WorldViewModel>();

Now we can change our dependency property registrations from this:

public static readonly DependencyProperty CameraLookDirectionProperty =  
    DependencyPropertyHelper<WorldViewModel>.Register(x => x.CameraLookDirection); 

To this:

public static readonly DependencyProperty CameraLookDirectionProperty =  
    DependencyProperty.Register(x => x.CameraLookDirection);
