hmm old post with no answer. In case the OP is still looking for an answer. ASP.Net is for developing web apps, not pc apps nor smart device apps but web based apps.

Yes you can create a web site using ASP.Net that will be viewable/useable on a smart device.

No you can not develop a actual application for a mobile device in it.
