How to use compiled global resources in ASP.NET MVC

I want to compile App_GlobalResources/Strings.resx into my assembly (and eventually use satellite assemblies for Strings.es.resx, Strings.fr.resx, etc.) but the following error occurs once the app is published:

"Could not load file or assembly 'App_GlobalResources' or one of its dependencies. The system cannot find the file specified."

Steps to Reproduce:

  1. Create a new ASP.NET MVC project.
  2. Add an App_GlobalResources folder and a Strings.resx file.
  3. Set the file's build action to 'Embedded Resource'
  4. Add a string to Strings.resx and use it in HomeController.Index(), e.g. ViewData["Message"] = Strings.MyTest
  5. F5 to debug, works fine.
  6. Publish to IIS and (since Strings.resx is excluded from publishing) you will get the above error in the published site.

Can ASP.NET MVC projects use string resources compiled into the dll and if so, what am I doing wrong?

Update: Here is what I see in Reflector: String Resources

So why is the ResourceManager not finding them? Isn't it supposed to fallback to the main assembly by default?

Here's a good starting point http://odetocode.com/Blogs/scott/archive/2009/07/16/resource-files-and-asp-net-mvc-projects.aspx

I setup a project just like you mentioned and got precisely the same error when I deployed to IIS6. Changing Custom Tool to PublicResXFileCodeGenerator and Custom Tool Namespace to Resources per Scott's suggestions cleared it right up.

I'd also follows Scott's lead with respect to eliminating App_GlobalResources but I got it to work just fine. That might be a matter of personal preference.
