CallMethodAction: can it be used in WPF?

Apr 25, 2013 at 5:55 PM
Hi,
When i use CallMethodAction in MVVM-WPF i get this error: "CallMethodAction" does not exist in the namespace "http://schemas.microsoft.com/expression/2010/interactions".

knowing that i include the following namespaces in my xaml:
xmlns:i="clr-namespace:System.Windows.Interactivity;assembly=System.Windows.Interactivity" xmlns:ei="http://schemas.microsoft.com/expression/2010/interactions"

And if it is for SL only, what is the equivalent in WPF
