Where is IPagedCollectionView?

This is nothing but a sticky note for me than a post. I downloaded a project and when I tried compiling the project I got an error from the compiler that it couldn’t find IPagedCollectionView. I checked the name space of the class in my other box and it pointed me to System.ComponentModel, I checked the references and I do have that dll. (One thing I did not check was to double click open the reference and see if the class definition there). Anyway, I went directly to the trusted source regarding these kind of problems, Microsoft msdn web site and found the missing dll. Even though the name space points to System.ComponentModel. the class definition is in System.Windows.Data.dll. So for future reference if you run into this problem, now you know, where it is
