Vincent Leung suggests you to check some courses which will teach you in
the fundamentals of Silverlight and Expression Studio.
Start with basic techniques and build your skills to create more advanced applications. Design Scenarios is comprised of four levels that increase in difficulty with three training modules per level. Each module deconstructs a Silverlight application to teach you must-know features and techniques.
All great applications start with a foundation in design. The Design Principles track gets back to basics with key design concepts that will help you create slick and functional web applications. Each of the four level groupings contains three modules, each focused on design fundamentals.
