Issues Migrating to Web Application Project

3/16/2008 2:14:53 AM

0/0

I just tried to migrate a Visual Studio 2008 VB.Net Web "Site" project (Targeting .Net 3.5, Using AJAX) to a Web "Application" project following this guide (I figured 05 and 08 must be basically the same on the process.) and ran into some major problems in trying to build the site.

When I build the site I get two types of errors, an example of the first is:

'Protected Sub Page_Load(sender As Object, e As System.EventArgs)' has multiple definitions with identical signatures.

And the second looks like this:

'RequiredFieldValidator1' is already declared as 'Protected WithEvents RequiredFieldValidator1 As System.Web.UI.WebControls.RequiredFieldValidator' in this class.

It appears each of these errors is repeated for every method and every control on every page. The compiler stops counting at 102 errors but when I start removing control declarations from the *.designer.vb files - which seems to take care of the second type of error - more and more of both types of errors just keep popping up.

Any ideas of what could be wrong would be greatly appreciated.

This sounds like you have two copies of everything. (E.g. if both the old-version.aspx.vb and new-version.aspx.vb are being included then both will contribute members to the same class because of the use of partial classes.)

Carefully double check what is being included (this might require a manual examination of the content of the .vbproj file).

I figured out the issue. First I'll give some background on my development habits. When I start a new asp.net project I usually create a "template" page which is a page that's already attached to a master page and may have some additional placeholder content in it. I'll then copy this file and rename whenever I need to add a new page. As it turns out VS doesn't change the partial class name when you do this, it leaves it the same as the original file. When I was running the site as a web "site" it didn't seem to care, but when I converted it into a web "application" the compiler saw that all the pages were the members of the same class and choked on it. I just changed each of my pages to have a unique partial class name and viola! everything worked.
