You are developing an ASP.NET MVC2 view and controller.
The application includes a class names Employee that has a LastName property. The controller requires an
action method that will insert an Employee
instance into a database.
You need to ensure that the data that is submitted is an Employee instance and that a LastName value is
given.

method as follows.
public ActionResult Create(FormCollection employeeToCreate)

public ActionResult Create(FormCollection employeeToCreate)
{…}
