LINQ to SQL and the O/R Designer in VS 2008

37 minutes, 59 seconds


Right click “Save as…”

In this in interview Young Joo, a Program Manager on the Visual Basic Team, talks about LINQ to SQL and the new O/R Designer in Visual Studio 2008. He demos a typical business client-server scenario and shows how LINQ to SQL classes make it much easier to work with relational data in SQL Server 2005. Young also talks about architectures where he sees using LINQ to SQL having the most benefits.

Learn more about the O\R Designer and LINQ to SQL by viewing our "How Do I" video LINQ series on the Visual Basic Developer Center.

  • Nice How-To vidoes, but now I know how it feels when the VB.net programmers see thing for C# only.

    Where is the:

    “How Do I” Videos — C#

    Are these videos available for C#? I looked under that section on the MSDN but found nothing related to LINQ to SQL or pretty web page like that for VB.Net.

    This is really AWESOME!! Thanks a million for sharing with all. Big Smile
  • Agreed, granted I can follow the video, but it would be nice to see C# versions
  • This is a brilliant tutorial, many thanks for sharing it with us

    Thanks so much to the both of you!  We REALLy appreciate you taking time out of your day to explain this to us.

    I had watched all of Beth's GREAT bindingsource videos, and was trying to make the leap to LINQ.  This was the missing (pardon the pun) LINK.

  • I wish I found this video a year ago.  This would have been a great help when I built my first LINQ to SQL site rather than the tutorials I used.  I built a weight loss quotes site and has few stumbles here and there which may have been lessened.  I was impressed with LINQ to sql in general though. Very quick to get started!

  • Truly a right-to-the-point, hands-on tutorial on Linq to SQL. Finally I can give up of manually writing SPs & Business Objects and use this more productive, type safe, easy way instead! Well done!!!
