Finding Unnecessary Library Links in Visual Studio

Question

I seem to be a bit carried away by the number of libraries that I reference in the ASP.Net MVC web application I'm working on. Are there any tools or features already built into Visual Studio 2008/2010 that tell me which links I don't need?
