Hi,
For those of you with an interest in Silverlight I thought you might like to take a look at a series of 'how to' videos available from the Silverlight team. You'll find everything from the basics through to best practices and even a series of tips and techniques.
For example, Todd Miranda shows how to dynamically add markers to a video at runtime and Peter Bahaa shows how to handle the back and forward buttons, all in Silverlight 1.0.
To browse the library of videos click here.
All the best,
Allison
