The VB team has made some nice improvements to intellisense that make it much easier to navigate through APIs. 

Intellisense completion now automatically filters the member list available as you type to help you better pinpoint the API you are looking for.  For example, if in an ASP.NET code-behind page you type "R" it will show the full list of types and members available (with the selection starting in the "R" list):

When you type the second character of what you are looking for (in this case "e"), VB will automatically filter to only show those types that start with "Re" and highlight the most likely option:

When you type the "s" it filters the list even further:

When you type "p" it filters down to just the one option available:

I find this cleaner and more intuitive than the previous model that always showed everything in the drop-down.
