Problem with split namespace

Visual Studio 2005

I have a web site that has a number of namespaces organized around different applications in their own folders.  One of the namespaces seems to have been split, and I'm not sure what to do to fix it.

In the object browser, one of them says:
Namespace Admin
     Member of: http://localhost/websitename/

The other reads:
Namespace Admin
     Member of: App_Web_gdppjhsq

classes of one namespace do not recognize classes in the other.  In my source I get "type not defined errors"  and it will refuse to build until I remove the variable declaration.

I thought this might be a problem with the temporary ASP.NET files, so I closed down visual studio, rebooted, deleted all the files in C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\Temporary ASP.NET Files and used iisreset.  Absolutely no difference.

Any ideas?

Did you add references to these different applications where you need them in an application

They are all in the same website... Most of them were developed separately and folded in by hand, but now they should be one big happy family.  In fact previously to my recently adding a new user control to the Admin namespace, the system worked fine.  The namespaces are really there to prevent collisions between similarly named classes in different folders.  

There isn't any cross communication between the previous applications.  The shared code is managed in two DLL libraries.

It seems like only the new usercontrol is causing the problem.  I've tried taking that usercontrol out of the namespace, but it still can't see items in the admin namespace, and they can't see it.

I'm also getting this message when I make changes to the usercontrol, unless I rebuild the entire solution:

Unable to cast object of type 'ASP.admin_grpcatoverview_ascx' to type 'grpCatOverview'.  grpCatOverview is the problematic usercontrol, which I am loading dynamically.  Is this related?

So far the only possible workaround I've found is to use late binding instead of defining those class types.

Argh!  It's been so long since I did the previous controls, that I forgot I needed to add the reference control statement at the top of the markup:

<%@ Reference Control="~/Admin/grpCatOverview.ascx"%>

Once that's added, the type is accessible in the code behind... So you were right, it was a reference problem.
