An interesting feature of Silverlight is how the interaction between visuals and logic (this is, between designers and developers) is handled. It uses a so-called Parts and States Model, which is ensured by a contract specified with attributes in the control class.
Jesse Liberty has made an excellent short post on this subject, which I strongly [...]

There’s no straight way of embedding YouTube videos in Silverlight. What you can do, however, is to create a floating div over the Silverlight plugin, whose content will be the YouTube video control. For this purpose, I’ve wrote a simple class to make it easier to do this.
The usage is simple:
