asp.net-mvc - Localized resx resources are not being loaded from App_GlobalResources folder when changing culture on the fly

Question

I have a solution consisting of two MVC3 projects with resources located in each project's App_GlobalResources folder:

MyApp.Web project's App_GlobalResources folder contains default resources (default culture is en-US) such as MyPage1.resx

MyApp.Web.Europe project - App_GlobalResources folder contains resources for European cultures such as MyPage1.de-DE.resx. It's a startup project.

When I change culture on the fly setting Thread.CurrentThread.CurrentCulture and Thread.CurrentThread.CurrentUICulture what I have is that resources from MyApp.Web.Europe App_GlobalResources folder are not being loaded.

In addition to that MyApp.Web core project also contains some resources in Resources folder for all cultures, so when I change culture on the fly, European resources such as de-DE are being loaded from Resources folder fine. Does someone have any considerations how to make them load from App_GlobalResources?
