.NET 3.0 RC1 (formerly WinFx) is available for the desktop but as a device developer you always feel left out. Well Roman Batoukov of the CF team gives us the lowdown on WCF for CF. Their choice for transport channel...email which is an interesting choice and somewhat agree for certain scenarios. Of course it's extensible so we are already thinking of some other transport channels we can develop for mobile/embedded devices because let's face it, not everyone runs Exchange :)
