So far, I’m a couple days intll that cloud services can, in fact, be ao PDC. The only VB code I’ve seen anywhere was code that I wrote myself. None of the presentations have been VB. There are very few labs that are VB.
Having said that, I can assure you that cloud services can, in fact, be written using VB.NET. Doing the lab in C# (as it was written) would have been too easy. So, despite having no support from Microsoft, I did it in VB.NET. I’ve also been talking to a few people to make sure those labs are released with good VB code.
