Update to Precompiled Site
<p>I have a .NET 2.0, precompiled and deployed web site.  I have decompiled the site and added new functionality to a 'dev branch' of the site.  I now need to upgrade the site to .NET 3.5, so that the new features can function, and add the new features to the 'production' site.</p>

<p>How can I go about this merge of features into the 'production' site?  I have several C# classes, new pages, and uncompiled source code for existing pages.  </p>
