The Windows Phone Toolkit is open source and you can download the source code from your Codeplex repository: http://phone.codeplex.com/ . This means that you can change whatever you like, compile the code, and then link these libraries, not the NuGet package.
Since you did not describe what you want to change, itβs hard to say how to change it exactly. If you edit the message and explain what you want to do, we will probably tell you how to do it.
