I haven't taken a VB.NET class in a long time, the only one I took was using the official Microsoft course material, which were not "advanced level". While I like Visual Basic .NET a lot (and I wrote and maintain several programs in it), I think you should shift to C# if possible, because it's the language most .NET apps are written in, and is the one your students will be asked to know, and there are lots of books on the subject. Is it a requirement that it be taught in VB.NET? You could teach some basics of asynchronous programming using the Background Worker (which is what I actually do use for basic GUIs :) )
