VS 2008 - Using LINQ To Execute A Simple "delete From Employees Where EmployeeID = 1"?

I am rewriting an old app that uses Linq. One part intrigued me...The code get the ID of a row from a datagridview.Then the code executes a LINQ that in the where-part make a selection based on the ID (which is the PK) to return a single object using .Take(1).SingleOrDefault Then this object is added to the dbcontext.Employees.DeleteOnSubmit() method and finally the Submitchanges is executed...I added a watch to the Log property of the datacontext, and lo and behold, when the delete query is executed, it uses ALL properties of the object in its where query. It should use the EmployeeID only since its the PK.

My question is, is it impossible using LINQ to execute a simple "delete from employees where employeeID = 1" That is basically what the above LINQ code does. But I dont want to to excute a select statement first, and I dont want it to delete by all columns, only by the id column, which an indexed PK.Any LINQ gurus wanna share some insight on this?
