Visual Studio 2008 - .Net Error: "The Type 'foo' Exists In Both "temp1.dll" And "temp2.dll" (pt 2)

Solution,I had also moved ashx and asmx files at the same time as this. The Class attribute of the WebService/WebHandler directives were pointed at the wrong namespace. The moral of the story is to make sure you view the markup for all as*x files you change the namespace for by right-clicking on them and choosing "View Markup".

I'm experiencing the same problem as in this question and this link, but none of the answers fixed my problem. (edit: Setting the web.config batch attribute works, but that's a coverup, not a solution)

The problem I'm having is with a User Control that I moved from the root directory to a subdirectory within the same Web Application project. It used to work fine before I moved it. When I moved it it started giving me the error message.

It's saying that the class name exists in two dll files in Temporary ASP.NET Files. Sure enough, when I open Reflector, it's in two dlls.

If I rename the class and ascx file, everything works fine. No usages of the original name exist within any of the files in my entire application. When I rename the file, I opened all of the dll files in Temporary ASP.NET Files with Reflector, and no references to the original class name exists.

So where's this phantom reference coming from how can I fix this?

Edit: I literally grepped every file in my working directory for the solution and my temp directory for the old class name and deleted every file that contained it. I then renamed back to the original, broken name and I still get the error.

Edit:Ok, so I did some more testing on what works and doesn't work.Let's say the original file name was "BadUserControl.ascx" in namespace "MyNamespace".

I moved the file to a directory called "NewDirectory" and changed the namespace to "MyNamespace.NewDirectory". There are no copies of "BadUserControl.ascx" anywhere else on my HDD. I double-checked my TFS history to ensure the ONLY difference is the addition of ".NewDirectory" to the namespace in the markup and code-behind files.

Inside of this namespace are two other user controls named "OtherUserControl" and "AnotherUserControl".

This situation fails:
I have 2 Register directives:

<%@ Register src="BadUserControl.ascx" tagname="BadUserControl" tagprefix="uc1" %>
<%@ Register src="OtherUserControl.ascx" tagname="OtherUserControl" tagprefix="uc2" %>

These situations work:
1) I keep "BadUserControl.ascx" named as is.
I have 1 Register directive on a page in the same namespace:
<%@ Register src="BadUserControl.ascx" tagname="BadUserControl" tagprefix="uc1" %>

2) I change "BadUserControl.ascx" to "GoodUserControl.ascx"
I have 2 Register directives:
<%@ Register src="GoodUserControl.ascx" tagname="GoodUserControl" tagprefix="uc1" %>
<%@ Register src="OtherUserControl.ascx" tagname="OtherUserControl" tagprefix="uc2" %>

3) 2 Register directives without BadUserControl.ascx at all:
<%@ Register src="AnotherUserControl.ascx" tagname="AnotherUserControl" tagprefix="uc1" %>
<%@ Register src="OtherUserControl.ascx" tagname="OtherUserControl" tagprefix="uc2" %>
