There are a couple of ways to do this. If your assignment explicity requires you to do it in
asp.net, then here's what i reccomend as places to start:

Asp.net has classes that aide in the development of handheld/mobile enabled web apps ("mobile controls") is the term.

While it depends on the details of your assignment--- if its not too sophisticaed then the easiest thing to do might be to do this in .net 1.1 by getting a free tool called "Web Matrix" which is lightweight and quick/easy to learn. Go here for web matrix:
www.asp.net/webmatrix/download.aspx
Here for a tutorial on developing mobile enabled web sites in webmatrix:
www.asp.net/webmatrix/gu...controls.aspx


If your assignment requires that you do this in asp.net 2.0 then Visual Studio 2005 (the primary dev tool for .net apps) also has tools that help you build mobile web apps. There are several different editions of visual studio, but it looks like you'll need to order a 90 day free trial copy of Visual Studio 2005 Professional (the visual studio web dev express edition is available for immediate download, but it apparently doesn't include the mobile web app tools).

Start the order process here: msdn.microsoft.com/trial/ (it is free, they don't charge you for the shipping cost of the dvd)

Good place to start for resources is here:

Hope that helps
