After adding "RelayCommand" class (that uses CommandManager class) into my Silverlight App I've got an error:

The name 'CommandManager' does not exist in the current context

This class is a member of System.Windows.Input namespace that is in PresentationCore.dll assembly. The problem is that I can't add this dll into my app...

I am having a strange assumption: this class (CommmandManager) can't be used in the Silverlight. Am I right?

How can I implement MVVM-pattern (http://msdn.microsoft.com/en-us/magazine/dd419663.aspx)?

Thanks.
