Inherit your controller from BaseController, and inherit BaseController from Controller class, put your global logic/validation on BaseController.

Example :

CustomerController.cs

public class CustomerController : BaseController
{

}

BaseController.cs

public class BaseController : Controller
{
 //Add your logic here
}

Thanks for the response

If I declare a viewbag on the BaseController can this be put on the Layout page via razor?

Hi amendoza,

Yes, we can do this.

It just like you pass viewbag from a controller to a view.

You could declare a public viewbag on the BaseController like : 

ViewBag.BaseName = "I'm the public base";

Then, in the Layout page, you can use this viewbag like this :

 @ViewBag.BaseName

Then the viewbag value is displayed in the public section of your page.

Yes, However you would better use the commonly used logic here, like checking a session, permissions, populating common functionality etc
