Do you get the same error is you name it "CustomIcon"?

Yes that made it work now isactive is throwing error
true is not a valid value for property elfisactive
i tryied to change isactive to elfisactive to see if this would resolve the issue as it did for the icon but still telling me its not a valid value cant see how as its setup as a bool

The documentation seems to say that the second parameter is the type of the property, but you seem to be passing in typeof(PackIconMaterialKind).

DependencyProperty.Register Method (System.Windows)

Registers a dependency property.
