The Internet Explorer Beta 2 was released yesterday introducing quite some new features about which you already probably read in one of the various like the IE8 Homepage or the announcement on the official IE Blog. However there may be a feature that isn't mentioned too often which is the fact that now with beta2 RIA technologies like Silverlight are also supported in the flyout of a WebSlice. This is something that wasn't available with Beta1.
And since it is not as obvious to integrate a Silverlight portion into a WebSlice I will give you a littel walkthrough on how to do that.
First of all I want to introduce you to the concept of the different sources from which a WebSlice can retrieve its information. To understand that we first need to differentiate between the two main components of a slice which is the button in the favorites Bar on the one hand.
