Honestly, it is a bit hard to answer to your question. The samples are very explicit, they show how to integrate our component into a Silverlight application. More specifically, the "Uploader Tour" sample gives a good and simple example of how to do this, so I'm not sure what else we can provide.
By default, the samples are located here :
