Why does the Entity Framework object still persist despite context.detach()?

Question

ASP.NET

I take out the object and manipulate it. and After saving, I get a copy of the object in the database, regardless of context.detach. And yes, the object is inside the using(context) {} section. What am I doing wrong . After all, in theory, the entity framework should stop tracking the object and not save it?
