what is the key different between ASP.NET 2008 with Web developer express 2008?
<p>// question has been modified</p>

<p>I start to learn ASP.NET and the book uses Web developer express 2008 as the development platform.
I would like to know what the key difference between using the professional VS 2008 and this free express version.</p>

<p>Thank you</p>
