Should I use App_Themes or Content/themes in MVC4?

Question

Up until now I had been using MVC3 for my apps but with the new update of Visual Studio 2012 I got MVC4. I migrated a few of my apps and now they are broken.

I noticed that the new project template for an Internet application creates a ~/Content/themes/base folder.

And yet, up until now I had been accustomed to use the App_Themes folder for that. In fact, with VS.2013 you can use "Add ASP.NET FOlder | Themes".

So I am now confused with MVC4, has It deprecated the App_Themes folder (which seems more appropriate to me than ~/Content) ? or is there a significant difference?

App_Theme come from ASP.NET Platform and one goal of mvc is get a clean html code

One of the things that ASP.NET MVC is missing is the ability to easily implement Themes. The older, more mature standard ASP.NET framework includes theme support via the App_Themes folder; however limited it can be, it’s still more than ASP.NET MVC currently has. Well, at least until I wrote this little custom ViewEngine and ControllerBase class to help out and allow us to very easily implement Themes within our ASP.NET MVC applications
