Well, you got the concept right, asp.net mobile project are not very
different form regular asp.net projects, all you need is a .net enabled
windows server and that’s all.
The key difference is that the devices can’t interpret HTML so content
should be rendered in another markup language like xHTML-MP, cHTML or WML
depending on the device, and not all asp.net controls have a equivalent in
those ML’s, so ASP.NET Mobile Web Forms is a subset of ASP.NET Controls that
can be effectively rendered in this ML’s.
Most mobile operators right know offer data access through a data carrier
depending on the technology, EDGE and GPRS for GSM operators and 1xRTT an
1xEV-DO for CDMA operators, but in general you can find data access in most
countries, finally that’s up to the users to chose the device and the
operator, asp.net will work regardless of this.
Finally for testing you don’t need a phone line, not even a real phone; all
you’ll need are device emulators that you can easily download from the web. I
recommend OpenWave Emulators (6.2.2 for xHTML and 4.1.1 for WML), and maybe
Microsoft Mobile Explorer (MME 3.0 ). If you pages work on this emulator,
they will work on most phones.
One funny thing is that some features of asp.net mobile web forms don’t work
on the Nokia emulator, but the work just fine in nokia phones.
Hope all this helps, if not, let me know.
