How to delete an object by id with entity framework

It seems to me that I have to retrieve an object before I delete it with entity framework like below

var customer = context.Customers.First(c => c.Id == 1);

context.DeleteObject(customer);

context.Savechanges();

So I need to hit database twice. Is there a easier way?

In Entity Framework 6 the delete action is Remove. Here is an example

Customer customer = new Customer () { Id = id };
context.Customers.Attach(customer);
context.Customers.Remove(customer);
context.SaveChanges();
