This is what VS 2010 runs automatically, but if you are using an older version of VS, you can get this functionality with third-party add-ons. For example, I used an add-in called RockScroll, which can highlight the use in the source file (by double-clicking on the word) http://www.hanselman.com/blog/IntroducingRockScroll.aspx ,
Also, ReSharper has built-in functionality with Cntl + Shft + F7
