Database connection issues

Hi,

I am trying to follow the steps in lesson 39. When I create the orderContext and then create the customerQuery, I don't see all the options for orderContext such as AcceptAllChanges. I only see a very few of them. I use visual studio 2012 professional.

I have SQL Server 2014 management studio, but I didn't download any .Net framework. Could that be why?

Thanks in advance!

Update:
I continued with the try-it example regardless, and my datagridview doesn't display anything. The code runs without an error except for the part that has:

Code:

        DataGridView1.Columns("CustomerId").Visible = False
        DataGridView1.Columns("Customer").Visible = False
        DataGridView1.Columns("OrderItems").Visible = False

I appreciate your help.

OK; here I found the answer to this very tricky problem:

It seems that visual studio 2012 has that issue.

Hi Shabnam,

Sorry I didn't have a chance to get back to you sooner.

I'm glad you figured this out. I hadn't seen this problem before and it's good to have the link you posted in case others have similar problems. On behalf of anyone who has this problem in the future, Thanks!

Sure; I hope it helps someone else too. I spent quite a few hours until I finally found it.
