I am using EntityFramework v6.1.2.

I read some articles and know about AsNoTracking extension.

When AsNoTracking is called, it means that if the entity is not attached, the context and the entity updated "should fail".

But I have tried and updated successfully, my code is in below: 

private readonly DemoObjectContext _objectContext = new DemoObjectContext();
var order = _objectContext.Orders.AsNoTracking().FirstOrDefault(x => x.Id == 1);(1 is the primary key)

order.OrderStatus = OrderStatus.Processing; // change the orderstatus
                //_objectContext.Set<Order>().Attach(order);
                _objectContext.Entry(order).State = EntityState.Modified;
                _objectContext.SaveChanges();

Is something wrong or did EntityFramework(6.1.2) changed something?

Please help me

No issues with EF. It works because Entry attaches the entity to the context.

See here for more details.

And on this SO specifically about Entry
