Getting App_GlobalResources assembly generated? (Error = CS0433)

I'm working on a ASP.NET MVC2 project, for which I have configured the localisation as follows …

I have a separate Resources assembly, containing all my resx files. The settings for each resx file are…

Build Action             = Embedded Resource
Copy to Output Directory = Do not copy
Custom Tool              = PublicResXFileCodeGenerator
Custom Tool Namespace    = Resources

I have a tool which exports the strings from a database into the resx files and calls the resgen.exe tool to recreate the designer.cs file.

This all worked great, even when I changed the language settings of my browser and refreshed the page. It would pick up the correct strings.

That was in a temporary working folder (I use subversion). I've now moved to working in my normal folder and am getting a rather odd error.

Compiler Error Message: CS0433: The
type 'Resources.XXXX' exists in
both
'c:\Windows\Microsoft.NET\Framework64\v4.0.30319\Temporary
ASP.NET
Files\root\6c657d01\aaca70ae\assembly\dl3\a36dac65\78c87110_3724cb01\Resources.DLL'
and
'c:\Windows\Microsoft.NET\Framework64\v4.0.30319\Temporary
ASP.NET
Files\root\6c657d01\aaca70ae\App_GlobalResources.g6fehiio.dll'

I have deleted all of my temporary asp.net files, re-run the web app and it regenerates both of the above mentioned assemblies. The really odd thing is that this all worked before I moved to my usual working folder.

So, can anyone tell me what is generating this App_GlobalResources assembly, which I don't need or want, because all my resources are contained in the Resources assembly I've created.

PS – The reason I went with Resources.dll was to get around a problem I was having with generating the resources using my database extract tool. (see here)

PPS – I am using VS2010
