If you are interested in free training for developing Silverlight Application using Microsoft Expression Studio Tools, you will want to head over to .toolbox.
The best way to describe the free training on developing Silverlight Applications is to take a paragraph from the about page on .Toolbox:
".toolbox features two core learning paths: Design Scenarios and Design Principles. Both begin with teaching basic techniques and build skills and knowledge incrementally. In Design Scenarios, designers and developers learn to create dynamically-rich Silverlight applications using Expression Studio. You will learn to add code-free functionality to designs by following step-by-step tutorials that illustrate how to create interactive user experiences. In Design Principles, you will learn fundamental design concepts (e.g., choosing the right colors and the right fonts) along with tips and techniques in how to apply them to your creations."
Learning how to build Silverlight Applications will also help you develop Windows Phone 7 Applications.
