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 inferred by the compiler without having to explicitly declare them. Type inference is one of the new features in Visual Basic to support LINQ.
