Question

I usually create ASP.NET websites and have a few classes I use, mainly a BaseClass. Normally I would change

public partial class _default : Page

to

public partial class _default : BaseClass

with a using at the top of the namespace name. However I don’t seem to be able to do this in MVC. How do I get my BaseClass or any other class into my MVC page?

The reason I ask is that I have a class called errors, I usually have this in my global.asax file:

void Application_Error(object sender, EventArgs e) 
{
    Exception objErr = Server.GetLastError().GetBaseException();
    namespace.errors.WriteError(Request.Url.ToString(), objErr.Message);
}

But I seem unable to do this, even with a shared namespace across the whole site

It is most probable that this question is lame but whatever 🙂

For the base class You can create ApplicationControler
Somethig like :

namespace YourApplication.Controllers
{
    public abstract class ApplicationController : Controller
    {
        public ApplicationController()
        {
            using(ApplicationDataContext menu = new ApplicationDataContext())
            {
                // loading data for menu control
                MenuRepository myMenu = new MenuRepository();
                ViewData["menu"] = myMenu.MenuList();
            }
        }
    }
}

And then you can just extend it from any controler
like this:

namespace YourApplication.Controllers
{
    public class DefaultController : ApplicationController
    {
        public ActionResult Index()
        {
            return View();
        }
    }
}

Notice in my example in application controler I am loading view that I am gonna display on every single page, and you can load anything you want, anything that you need often or always. Thats pretty much your base class.
