What are the major differences between VB Express 2008 (pro) and 2010?

I sometimes hack from some code for a friend. He paid for VB Studio pro 2008 but won't upgrade to 2010. He's happy enough for me to use VB Express 2008, but I am wondering what I am missing out on by not usi开发者_如何学Pythonng 2010.

What are the major differences beteen

 VB EXpress 2010 and VB Express 2008

and

 VB EXpress 2010 and VB Studio PRo 2008

?

Thanks.

Visual Studio Express limitations are best described here:

The best place to check and compare Visual Studio 2010 versions is this:

Differences between 2008 and 2010 versions can be checked in a white-paper provided here:

I've never seen a comparison between VBExp2010 and VSPro2008, but here's a comparison of 2008 versions: Visual Studio 2008 Product Comparison Guide

To compare the express versions of 2008 and 2010, I'd say the best way would be to just find out what's new in VB. Here's a video showing off many of the new features: What's New in Visual Basic 2010?
