My ASP.NET MVC2 application is developed using
1. VS 2010
2. Linq To SQL for Models
Here is Call controller code:
namespace CallTrackMVC.Controllers
{
public class CallController : Controller
{
private CallTrackRepository repository;
public CallController():this(new CallTrackRepository())
{
}
public CallController(CallTrackRepository newRepository)
{
repository = newRepository;
}
}
}
Error on IIS7 when browsing the Call Create page is
NullReferenceException: Object reference not set to an instance of an object.]
CallTrackMVC.Models.ExecOfficeDataContext..ctor() in C:\ClearCase\rartadi_view\STS_Dev_TEST\CallTrackMVC\Models\ExecOffice.designer.cs:71

Code in Global.asax is
protected void Application_Start()
{
AreaRegistration.RegisterAllAreas();
RegisterRoutes(RouteTable.Routes);
}
Any suggestion would be a great help.
