[WPF] how to apply standart themes?

[Poly]

I know that there is some standart themes that i can use in my WPF
application, like luna, aero etc.
But i dont understand how to use, apply them in my application.

Do anyone knows how to make all my application in for example
royale.normalcolor theme?

Many users spend ages setting up a theme to their liking, why would you
want to override the user's choice?
