You think you know Silverlight... but how well do you really know Silverlight? Did you know, for example, that Silverlight 3 features two very different networking stacks and that one of them can be used to circumvent the most frustrating limitations of Silverlight networking? Did you know that ComboBoxes can be virtualised for high-performance? Or that the BCL now includes support for CPU metrics? Join the fun as Jeff takes you on a backstage tour of Silverlight and presents it in a way you've never seen it before.
