Integrating System.Windows.Interactivity into Your WPF Project

Many developers face challenges integrating the System.Windows.Interactivity library into their WPF projects. While previously this often involved Expression Blend, a more straightforward method now exists.

Solution: Using the Open-Source XAML Behaviors

Microsoft's open-source XAML Behaviors for WPF offers a simple solution. Here's how to integrate it:

Step 1: Remove Existing References

Begin by removing any existing references to "Microsoft.Expression.Interactions" and "System.Windows.Interactivity" from your project.

Step 2: Install the NuGet Package

Install the Microsoft.Xaml.Behaviors.Wpf NuGet package via your NuGet Package Manager.

Step 3: Update XAML Namespaces

In your XAML files, replace the namespaces:

• "http://schemas.microsoft.com/expression/2010/interactivity"
• "http://schemas.microsoft.com/expression/2010/interactions"

with "http://schemas.microsoft.com/xaml/behaviors".

Step 4: Update C# Using Statements

Finally, update your C# files, replacing:

• "Microsoft.Xaml.Interactivity"
• "Microsoft.Xaml.Interactions"

with "Microsoft.Xaml.Behaviors".

These steps ensure seamless integration of System.Windows.Interactivity functionality, enhancing your XAML applications with added behavioral capabilities.
