Q:

Localization doesn't kick in, in ASP .NET MVC

I followed this guide which I was recommended, but I can't get it to work at all.  When I refer to my string resources, I'm not seing a visual change when I navigate to the page with my browser.  
I have only Danish as my viewing language, and I checked to see that the Accept-Languages header does indeed contain da-DK.  My resource's name is DashboardMenu.da-DK.resx. 
Edit 1
I am modifying the UI culture and the normal culture in the following way, in my system.web section of my web.config file:
<globalization culture="auto" uiCulture="auto"/>

The way I am using my resources is the following way (resource files under a directory in my View folder for that the given controller):

I am then using the resources in the following way (showing you DashboardOverview.cshtml in the Teacher view folder. 

Edit 2 It should be noted that I am using IIS Express 7.5. 

A:

I managed to solve the issue.  Turned out that my files should be named ".da.resx" instead of ".da-DK.resx".
