How to add System.Windows.Interactivity to project?
c#, wpf
Solution
The official package for behaviors is `Microsoft.Xaml.Behaviors.Wpf`.
It used to be in the Blend SDK (deprecated). See Jan's answer for more details if you need to migrate.
Problem
My project missing `System.Windows.Interactivity`. Google says that I have to install Expression Blend, but on my other computer I have this library and I don't have Expression Blend installed. So there should be another way to obtain `System.Windows.Interactivity`? What should I do? (right now i don't have another computer so I can not just copy this library :)
