Infinite scrolling in Silverlight

I've found a few questions about infinite scrolling already posted, but none were about Silverlight, so I thought I'd ask. I've done some initial searching, but haven't been able to find any reference material on how to implement infinite scrolling in Silverlight. This is more of a brain-storming exercise so 开发者_StackOverflow中文版I can get some thoughts on different ways to implement this.

Looking for something like that?

I've just published some blog posts and a sample which effectively implement infinite scrolling in Silverlight. See this answer.
