DRAG DROP
There is MS Visual Studio 2010 and MS .NET Framework 4 application PassGuideApp.
PassGuideApp uses this service to connect to a MS SQL Server 2008 database
PassGuideDB.
To access data from PassGuideDB ADO.NET Entity Framework is used.
PassGuideApp manages Product and Product_details records.
A new Product_details record, for an existing product, is added. How can you associate the
new Product_details record to the correct Product details.
Answer: 
Explanation:
Another shit question, not clear whether the new Product_details record was added to database, or merely created in memory. Based on available choices, I’ll assume the idiots creating this question meant a new Products_details ENTITY was created, and we want to associate it with appropriate Products entity.
The way to do it is as following:
Context.Products.AddObject(Product_details)
So to translate to the available answers it would be:
For the Products entity…
…use the Add Object method…
…add the Products_details entity.

I don’t like this answer, and I hope this fucked up/imprecise excuse of a question does not come up during exam.
