development windows vista

Hi,
I have learned that MCE under vista will not be shipped as a separate edition but as a feature under vista home premium and ultimate. However, the SDK for development of applications etc are going to be released a single compilation.
My question is, If on a WPF enabled machine I develop an application using the WPF APIs, how will it run on vista versions which dont have MCE runtime.
Thanks in advance
