Difference between "Smart Client Contrib" and "Prism Contrib"

Jun 16, 2008 at 2:26 AM
I am a newbie. I am just wandering around to get Smart Client Guideline for WPF for recent few months. That time I just came to know about "Smart Client Contrib" and started using it in my application. I am confused on seeing the project "Prism Contrib". I have downloaded some sample applications in Prism which looks same like SmartClientContrib.

Could you please explain me the difference between "Smart Client Contrib" and "Prism Contrib"? If both are similar which way should I have to use?
