Use Microsoft.Xaml.Behaviors.Wpf instead the System.Windows.Interactivity

[punker76]

Use Microsoft.Xaml.Behaviors.Wpf as dependency from NuGet instead the System.Windows.Interactivity.dll

This will remove the reference to System.Windows.Interactivity.dll which is sometimes bad for other projects which are also use this dll.

With this change it's necessary to change the namespace too, so this is a breaking change for all others too.

Steps to migrate:

1. Remove reference to Microsoft.Expression.Interactions and System.Windows.Interactivity
2. Install the Microsoft.Xaml.Behaviors.Wpf NuGet package.
3. XAML files – replace the xmlns namespaces http://schemas.microsoft.com/expression/2010/interactivity and http://schemas.microsoft.com/expression/2010/interactions with http://schemas.microsoft.com/xaml/behaviors
4. C# files – replace the usings in c# files Microsoft.Xaml.Interactivity and Microsoft.Xaml.Interactions with Microsoft.Xaml.Behaviors

Maybe you are trying to mix types from Microsoft.Xaml.Behaviors.Wpf and System.Windows.Interactivity?
Are you using both assemblies?
