Channel 9 Interview: Type Inference in Visual Basic with Bill Horst

Published 08 November 07 03:22 PM
I just posted an interview on Channel 9 with Bill Horst, a member of the Visual Basic QA team. Bill shows us the ins and outs type inference in the newest version of Visual Basic in Visual Studio 2008. He shows us how the new Option Infer works and how various types are infered by the compiler without having to explicitly declare them. Type inference is one of the new features in Visual Basic to support LINQ.

Also make sure to check out these LINQ How-Do-I videos on the VB Dev Center.

Enjoy!

Hi beth,

I followed your forms over data video series it a very good resource for windows form. I have an issue with the updating related table video example. I tried to add a new row to the parent record, it won't add and i debugged, but  found out the rowstate value is Detached on the bindingsource  instead of add. so the master record couldn't add, so can't add the child record either. Is there something am missing,Please Help?
