The Customer and Order Entity Classes

In the previous post we dragged the Customers class from the Northwnd database onto the LINQ Object Relational Designer. A number of things happened when we did this:

  • A class called Customer was created. This class maps directly to the Customers table in the Northwnd database.
  • The DataContext was modified. I will describe how it was modified later in this post.

When a developer accesses an instance of the Customer class, it is almost as if they have direct access to the Customer table in the database. Figure 1 shows the fields of the Customer table as they appear in the Object Relational Designer.

I wish not concur on it. I think nice post. Especially the designation attracted me to be familiar with the whole story.

I've asked this question on Yahoo! Answers before, but it did not work out at all. My computer started freezing out of random, so I rebooted my computer entirely. But after the reboot, it still does it. I have only 12 programs installed, which are: -Adobe Fireworks CS4 (NEEDED) -Adobe Flash Player Plug-in (For Mozilla Firefox) -Apple Application Support -Apple Software Update -AVG Free 9.0 -Belkin Wireless Utility (My Internet) -Camtasia Studio (NEEDED) -Free Registry Repair (Tried To Fix With This) -Google Chrome (NEEDED) -Java(TM) 6 Update 17 -Microsoft Visual C++ 2005 Redistributable -Mozilla Firefox 3.5.6 (NEEDED) -Quicktime Pro 7 (NEEDED) -Registry Easy v5.6 Pro (Tried To Fix With This) -Windows Explorer 8 -Windows XP Service Pack 3 -WinRAR Archiver Pro (NEEDED) My Computer is 10 Years Old. A Compaq FS740 Monitor with a Compaq Presario Tower. I have different problems every time I HAVE to reboot. I Full-Scanned the computer with my AVG Free 9.0, and no viruses were found. I don't know if it's either a problem with the Registry, a Virus, or something else. What can I do to stop this random freezing? [url=http://gordoarsnaui.com]santoramaa[/url]
