After importing my color scheme from Visual Studio 2008 into Visual Studio 2010 I found a problem with the color used to highlight references. The background highlight shows up on the text under the caret for things like variables, functions, classes, etc. and any text that is a reference.

I created a short video to show how to deal with this issue.

The setting in Visual Studio 2010 is under the Tools…Options menu.

Go to Environment… fonts and colors… Display item Highlighted Reference and change the item background.  If you want to get rid of the Highlighted Reference color then choose an item background of Automatic.

I hope this helps someone
