Before moving on to SQL Express SP2, I decided to finish with VS by installing the Pocket PC and Smartphone 5.0 SDKs. On XP, you need to install ActiveSync first. So I started to install ActiveSync 4.2 and, what do you know, ActiveSync is blocked on Vista.

I found the Windows Mobile Device Center here. It is the Beta 3 Release for Vista RC1. I installed it.

I also notice that with this you can synch content with a Windows Mobile 2003 or 5.0 device. So, my Pocket PC running version 4.20.0 that syncs fine on XP won't synch on Vista, eh? Good to know.

So then I started installing the Pocket PC SDK and it complained that ActiveSync 4.0 is not installed on the computer and is required. You can ignore that message, which I did. The install of that SDK, and the Smartphone as well, went fine and I could create a simple device application.
