I blogged before about some of the promising new features for working with relational and XML data in C# 3.0. Those features will be revealed at PDC 2005 by Paul Vick (the equivalent of Anders Hejlsberg in the VB world). As with generics, VB developers will not be left in the cold because Visual Basic 9.0 will get the same features.
Maybe VB will get more of the dynamically typing that I blogged about than C#, because VB has always been good at supporting dynamic typing (since long before the first .NET version of VB). Paul Vick alluded to this in July. This is going to be very interesting at the PDC. I hope that I don't have to switch to VB to get those features 😉
