Question
I have a SQL Server table in Entity Framework named employ with a single key column named ID.
How do I delete a single record from the table using Entity Framework?
Accepted Answer
It's not necessary to query the object first, you can attach it to the context by its id. Like this:
var employer = new Employ { Id = 1 };
ctx.Employ.Attach(employer);
ctx.Employ.Remove(employer);
ctx.SaveChanges();
Alternatively, you can set the attached entry's state to deleted :
var employer = new Employ { Id = 1 };
ctx.Entry(employer).State = EntityState.Deleted;
ctx.SaveChanges();

You can use SingleOrDefault to get a single object matching your criteria, and then pass that to the Remove method of your EF table.
var itemToRemove = Context.Employ.SingleOrDefault(x => x.id == 1); //returns a single item.
if (itemToRemove != null) {
Context.Employ.Remove(itemToRemove);
Context.SaveChanges();
}
