<p>Is there an easy way to find the number of classes contained within a visual studio solution?   Other than writing a funky find script, I couldn't find a way to do it within the code metrics piece of VS.  </p>

<p>I am running Visual Studio 2008 and this is a VB.Net project through and through.</p>

<p>thanks!</p>

I haven't used these tools before, but they probably have some facility that can help you.  Basically any code metrics package can help.  VS 2008 was supposed to have a built in code metrics tool, but I think it was nixed for one reason or another.
CodeMetrics Plugin for Reflector
NDepend
- commercial I think, though has a trial download
--Edit--
JRoppert is correct.  I actually remember reading that the metrics tool was only available in the Team edition, not in Pro or Express
