Visual Studio 2010 offers a variety of new features, one of them I am particularly fond of is the extended IntelliSense. IntelliSense is pretty much as good as it gets in Visual Studio 2008 but Visual Studio 2010 pushes things a bit further.
There are two really neat new features in IntelliSense, the first one is the Pascal capital letter recognition which means that if you would like to find, let's say, the IsPostBack page property you can type IPB and you get a list of members with those three capital letters in their name. The second feature is the Camel case recognition which means that if you search for a key word let's say, Post, you will get all the members that have the word Post in their name.
Take a look at the two screenshots below:
