How to add System.Windows.Interactivity to project?
Solution 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:
- Remove reference to “Microsoft.Expression.Interactions” and “System.Windows.Interactivity”
- Install the Microsoft.Xaml.Behaviors.Wpf NuGet package.
- 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
- C# files – replace the usings in c# files “Microsoft.Xaml.Interactivity” and “Microsoft.Xaml.Interactions” with “Microsoft.Xaml.Behaviors”
Solution 2:
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.
Solution 3:
There is a new NuGet package that contains the System.Windows.Interactivity.dll that is compatible with:
- WPF 4.0, 4.5
- Silverligt 4.0, 5.0
- Windows Phone 7.1, 8.0
- Windows Store 8, 8.1
To install Expression.Blend.Sdk, run the following command in the Package Manager Console
PM> Install-Package Expression.Blend.Sdk
http://www.nuget.org/packages/Expression.Blend.Sdk/
Solution 4:
The easiest way might be to get it from NuGet:
http://www.nuget.org/packages/System.Windows.Interactivity.WPF/
Solution 5:
With Blend for Visual Studio, which is included in Visual Studio starting with version 2013, you can find the DLL in the following folder:
C:\Program Files (x86)\Microsoft SDKs\Expression\Blend\.NETFramework\v4.5\Libraries
You will have to add the reference to the System.Windows.Interactivity.dll yourself though, unless you use Blend for Visual Studio with an existing project to add functionality that makes use of the Interactivity namespace. In that case, Blend will add the reference automatically.
