Previously, T4MVC supported multiple Area folders, and we configured them like this.
<AreasFolder>
<Area>Apps</Area>
<Area>Modules</Area>
</AreasFolder>
We break our applications up into higher-level areas, and reusable components, each of which can have their own Views, Controllers, and Models folders, and other various folders containing things related to that part.
I am not sure exactly when this was dropped, but this is no longer supported and only accepts a string for the Areas folder.
Was there a reason for this?
