I posted this on stackoverflow: http://stackoverflow.com/questions/42397136/proper-way-to-route-to-controllers-in-umbraco-asp-net-iapplicationeventhander

I am trying to understand the proper way to route controllers in Umbraco when you put all your models, controllers, helpers, etc,. into their own core for a multi-site setup. My structure is as such:

MyApp.Core
--Properties
--References
--bin
--Events
  |EventHandlers.cs
--Directory
  --Controllers
    |DirectoryController.cs
  --Helpers
    |ContextHelpers.cs
  --Models
    |DirectoryModel.cs
--AnotherSite
  --Controllers
  --Helpers
  --Models
  --Services
--Shared
  --Controllers
    |HomePageController.cs
  --Helpers
    |Extensions.cs
|app.config
|packages.config

MyApp.Umbraco
--Properties
--References
--bin
etc........
--Views
  --Directory
    --Partials
      |DirectoryFilters.cshtml
    |DirectoryBase.cshtml
    |DirectoryHome.cshtml
    |FDirectory.cshtml
    |SDirectory.cshtml
  --Partials
  --Shared
  |Base.cshtml
  |Web.config
etc........

I posted all my code, that works on StackOverflow, but what would be the ideal way to handle the routing to the custom controllers in this type of setup? Having to create an action for every page in a website doesn't seem efficient.
