And they finally integrated the Analyzer feature into Visual Studio. Now you can find out where a specific call is bing used, right from your editor. I find this feature immensely handy when trying to figure our how to use a certain feature. This is especially handy when you're working with scarcely documented libraries like parts of the TFS Client Object Model. Find code in TFS Web Access that's using the same API to find out how you're supposed to call it.
