At the SharePoint conference Bill Gates announced the availability of Software + Services blue prints. One of the early releases of these upcoming blue prints is the Silverlight for SharePoint blueprint.

Software-plus-Services Blueprints are a series of source code and guidance packages designed to provide an architectural bridge between vision and implementation by making it easier to build Software-plus-Services applications.

Check out the availability of the source code and samples on how you can change the end user experience of your SharePoint users by using these blue prints.
