c# - How to add System.Windows.Interactivity to project?

Question

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 :)

Answer 1

Although this issue is quite old, i think this is relevant news / the most recent answer: Microsoft open-sourced XAML Behaviours and posted a blog post how to update to this version: https://devblogs.microsoft.com/dotnet/open-sourcing-xaml-behaviors-for-wpf/

To save you a click, this is the main 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”
