Entity framework DbContext update value without query and by foreign key

Question

I have a method for updating some tables. For update I need get first of TestProcess, but I don\'t like that. How can I update TestProcess without

Answer 1

You can do like that (you probably should have all the test process data):

TestProcess pr = new TestProcess();

pr.Id = id;
pr.UpdateID = updateID;

context.Attach(pr);
context.ObjectStateManager.ChangeObjectState(pr, EntityState.Modified);
context.SaveChanges();
