The most significant certification in WPF?

I want to give myself a goal to learn WPF. Tell 开发者_JS百科a certificate that must pass to be sure that I know WPF.

I'm interested in both free and paid certificates.

I think there is a newer certification available. The focus is now not only WPF, also Forms and .Net
