How to use System.Windows.Interactivity windows phone 8.1

I've created a wpf C# project for windows phone 8.1 following MVVM Pattern.

I want to install the System.Windows.Interactivity dll so i can use the event trigger and EventToCommand and so on.

The problem is that once i reference the dll in my project, i got an error saying:

Unable to find the type System.Windows.DependencyObjectCollection`1 in system.windows.dll module

I got the DLL from :

C:\Program Files (x86)\Microsoft SDKs\Expression\Blend\Windows Phone\v8.0\Libraries

I believe there is an incompatibility but when i look on internet i can see that some people use that library so i probably do something wrong when i add it..

I don't really understand.

Thank you for reading and helping,

Guillaume.

Solution

  • A compatible v8.1 System.Windows.Interactivity was distributed with the Windows Phone SDK. If I recall correctly, it should show up when adding references by going to Assemblies > Extensions, but if not look in

    C:\Program Files (x86)\Microsoft SDKs\WindowsPhoneApp\v8.1\ExtensionSDKs\BehaviorsXamlSDK*
