VS2013 ASP.NET 4.0 Usercontrols. Circular file references are not allowed

Our developers are getting the following 2 errors when building ASP.NET websites in Visual Studio 2013 specifically, which we never got before:
"The type exists in both ... and ..." and "Circular file references
are not allowed.". The 'File' field in the error is always a
usercontrol.
A few forum posts suggest adding batch="false" to the compilation section in the web.config, but this does not work, build successfully once, then next build fails again.
I installed VS2013 Update 2. No change. Our projects always build successfully on previous versions of VS, we made not code changes.
Anyone have any suggestions?

New ASP.NET MVC 2 ViewMasterPage error

Im trying out ASP.NET MVC 2 and have immediately hit a problem with my first application.When adding a View Master Page I get the following warning in VS 2008:
\Views\Shared\ViewMasterPage.Master: ASP.NET runtime error: The specified module could not be found. (Exception from HRESULT: 0x8007007E)Why is this? The System.Web.Mvc dll
is in the correct place and is referenced properly. I also have MVC 2 RC installed, Anyone have any ideas?
Check your projectproperties for the targeted .NET framework (under "Compile"->"Advanced Compile Options") and check the web.config values for added assemblies (System.Web.Mvc in version 4.0.0.0)
When migrating our project to MVC2 the wizard did not update these values and I had issues with my views.
Maybe this is what is preventing you from using MVC2?

Visual Studio "Convert to Web Application" and "Could not load type" errors

I'm currently getting a "Could not load type UI.Administration.Site.master" error message and I'm not really sure as to why.
I have an ASP.NET MVC Project with the UI namespace. Within the project's structure, I have an Admin folder. I right clicked on the Admin folder and chose "Convert to Web Application", but am getting a Could Not Load Type error for my master page.
Are there any special things that must occur in these situations for this to work?
ERROR INFO BELOW
Parser Error
Description: An error occurred during the parsing of a resource required to service this request. Please review the following specific parse error details and modify your source file appropriately.
Parser Error Message: Could not load type 'UI.Administration.Site'.
Source Error:
Line 1: <%# Master Language="C#" CodeBehind="Site.master.cs" Inherits="UI.Administration.Site" %>
I had always wondered what this command did. I'm sure I've tried it and seen no result. I finally just looked it up:
"Convert to Web Application" has nothing to do with your scenario. It's for converting Visual Studio .NET and Visual Studio .NET 2003 to Visual Studio .NET 2008.
See "Walkthrough: Converting a Visual Studio 2002 or 2003 Web Project to a Visual Studio 2008 Web Application Project".
Make sure your namespaces match up with your folder structure as well as in your Inherits clause and your CodeBehind attributes. I had the same problem and it was because the namespace in the Inherits attribute didn't match up when I converted.
