It's easy and, in most part, fully automatic, but... Do you have Visual Studio? What version?
Why 3.5, not later? (3.5 is quite a good version though, based on 2.0).

Visual Studio upgrades the solution and projects automatically, with your confirmation. Did you try it?

Oh, I see, you did... Probably, your original code was inaccurately written. Well, just resolve all the problems manually, one by one, looking at the MSDN help as you go. It should be easy...

Hi I think your project can not find UpdatePanel on the System.Web.UI namsespace please look at the UpdatePanel namespase, maybe it was not .net component and you should add some dlls at your project reference
