I’ve received several requests for publishing the MultiTouch Behaviors on the NuGet gallery so I created a simple package containing support for the Windows Phone and Silverlight platforms.
To enable your project for MultiTouch, just run the following command in the Package Manager Console and all the libraries and dependencies will be added to the Visual Studio project:
PM> Install-Package MultiTouchBehaviors
Alternatively just search for the package selecting Tools->Library Package Manager->Manage NuGet Packages for Solution from Visual Studio 2012.
If you are interested in creating a NuGet package for your open-source project, register an account here in the gallery and follow the instructions described in the section “Creating and Publishing a Package“: they are very clear and contain detailed information about the process.
The package definition for MultiTouch is also available in the Source Code section on CodePlex.
