Visual Studio :: Error CS0433 - Type Exists In Two Locations
Jan 10, 2011
I am using VS 2010 with an ASP.Net web application (FW: 3.5). When I run the app in VS, I get the following message:
c:WindowsMicrosoft.NETFrameworkv2.0.50727Temporary ASP.NET Files
oote7d09027703efd1App_Web_commandmodule.aspx.98f065d9.hwdz-ui2.0.cs(150): error CS0433: The type 'ASP.commandmodule_command_master' exists in both 'c:WindowsMicrosoft.NETFrameworkv2.0.50727Temporary
ASP.NET Files
oote7d09027703efd1App_Web_command.master.98f065d9.5f4zhfs0.dll' and 'c:WindowsMicrosoft.NETFrameworkv2.0.50727Temporary ASP.NET Files
oote7d09027703efd1App_Web_ltl_wu4_.dll'
I have deleted the temporary files/folders and as soon as I run the app, I get the same message and the files reappear. This is a show stopper and I do not know where to turn. I have searched the web, but the only thing I found was suggestion to delete the folders, which did not work.

I just upgraded my blog [URL] to BlogEngine 1.6.1 (from 1.6.0) in order to use the reCaptcha extension. I upgraded my local code from 1.6.0 to 1.6.1, then published via FTP through WebMatrix. After the upgrade, I am getting this error:
Compiler Error Message: CS0433:
The type 'Resources.labels' exists in both
'c:windowsMicrosoft.NETFrameworkv2.0.50727Temporary ASP.NET Files
oot9fd92f8745a2ba06assemblydl3a64307f6f14811b8_0291cb01App_GlobalResources.DLL'
and
'c:windowsMicrosoft.NETFrameworkv2.0.50727Temporary ASP.NET Files
oot9fd92f8745a2ba06App_GlobalResources.md7pit6m.dll'
The source file and line number where it breaks varies, but it is always the same basic message. What differs is the "md7pt66m" section of the App_GlobalResources.md7pit6m.dll (the second file path in the error message). I was able to fix the error locally by deleting the Temporary ASP.NET Files, but I can't do this on my hosting server (GoDaddy). Is there something I can do to fix the error? Based on suggestions from the codeplex discussion page, I have edited web.config file in order to cycle the app pool, and renamed BlogEngine.Core.dll to BlogEngine.Core2.dll and then back in order to restart the blog. I have also added batch="false" to the <compilation> tag in web.config (based on this post). I have turned custom errors off, so you can see the error on my site now.

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" %>

I have been reading many other posts on this and can not find the resolution to my issue. My problem is that i'm trying to create a visual studio project for a application that was created years ago with no project. So I have a class file in the app_code directory and I have set it's build action to "Compile" because one of my aspx pages did not find the class that was being accessed. After doing this and running the application I get the CS0433: The type '*********' exists in both error. Both paths go through the temp asp net files. The developer of this app has this call in a aspx page
MyUtils utils = new MyUtils();
Then in the global.asax he has
MyUtils Util = new MyUtils(); This is where the error occurs.

In a MVC2 project I moved a file from App_code to Content folder, compile it. Then move it back again to App_Code and then changer its Build Action to "Compile". Now I get this error and I don't know how to fix this to make my program work again:

I started an app in VS2008. I did it as a web site. I installed VS 2010 (yay) today. I wanted to start over as a web project. I made a Master Page. I made content pages. One of my content pages has a form on it. Super simple text boxes and submit.
I added a folder called App_Code and placed my class files there by doing Add New Item and pasting the code into the new class. I have person and persons. The persons collection class references person. In the same folder, the persons class finds the person class. Up one level in a page's code behind, I am gettingthe error
The type or namespace name 'person' could not be found (are you missing a using directive or an assembly reference?)
For giggle, I move person.cs up a folder. Still cannot find the person. Persons collection class still CAN find person. My code behind cannot find it.
A little reading tells me I have to set that folder as an app folder in IIS. I am running Windows 7 ersonal... I cannot find IIS. If not there, I ask myself what they heck is my app running under?
for being such a noob. Anyone know what is going on here?

I've just gone thru a large-ish project and renamed A LOT of namespace directives. Everything works fine on my developer box - deploy it to stage and I get:
Compiler Error Message: CS0433: The type 'ASP.usercontrols_pageheader_ascx' exists in both
'c:WINDOWSMicrosoft.NETFrameworkv2.0.50727Temporary ASP.NET Files
oot89252a5f7305b927App_Web_hodsbmv3.dll' and '
c:WINDOWSMicrosoft.NETFrameworkv2.0.50727Temporary ASP.NET Files
oot89252a5f7305b927App_Web_pageheader.ascx.6bb32623.bs4iljip.dll'
Yuck. Very similar to this: Deployment Project dlls cause 'type x exists in both' errors, but must be coming from a different cause.
I have none of the problems I've seen mentioned in other articles (App_Code / CodeFile directive). Worked out why it works on my machine: the website has no problem when it is in a vdir. If I remove the "PageHeader" usercontrol from the masterpage it lives on everthing is fine. If I rename "PageHeader" everything is fine. Updated: renaming the usercontrol doesn't help.
I'd had a look at the assemblies mentioned in the error in reflector; App_Web_hodsbmv3.dll contains dynamic classes for all the usercontrols in my project. App_Web_pageheader.ascx.6bb32623.bs4iljip.dll' contains the same code just for the PageHeader usercontrol. Why would ASPX decide to create the same class in two assemblies?

I had search from google about this error and try a lot of solution but still getting the error.
I had tested the following solution
1.) Delete the temp folder in C:WINDOWSMicrosoft.NETFrameworkv2.0.50727Temporary ASP.NET Files and rebuild the project
2.) Double check did any duplicate files name and dll in the same folder.
3.) remove dll files in bin folder manually and rebuild the project.

I have an asp.net web site. The reason I'm using web site instead of web application is that my project uses Sitefinity CMS system which uses the web site model.
I have several web user controls (ascx and code behind). I need a reference in the code behind of one control to another. I'm using the following code:
[Code]....
SilverlightShowHeader is the name of the class (the second control) which I need to reference. I haven't set any namespaces for both controls.
When I try to build the web site it shows the following error:
The type or namespace name 'SilverlightShowHeader' could not be found (are you missing a using directive or an assembly reference?)
Is that normal and how can I avoid it?
