When would you do a desk top app rather than ASP.Net

I asked about this in the VB.net forum, but I want to see if there is a difference of opinion here.

What are the reasons you would decide to do a dot net app in the
Windows desk top mode, rather than in ASP.Net? I am being asked to
make a recomendation and I can not think of any reason to go with desk
top, even for something that is only going to run on one desk top
computer at a time.

My thinking is that with Win XP you can always use IIS and run the app
on your desktop. If you ever need to migrate to a web app it will be
so much easier if you start out with ASP.Net, and in dot net it doesn't
take any longer to develop in ASP.Net.

So those are my thoughts but I am not an experience dot net developer,
so tell me what I am missing.

Depends on what your app is and does. You dont write a data crunching app using a Web solution where you need to worry about time out issues and holding open records etc.

You have more control over design and functionality creating a windows application vs a web based solution. Your also requiring your users have IIS installed, or that they have an internet connection if they are accessing a remote server.

There is a lot of variables depending on what kind of App it is, what it will be accessing, does it have some intensive IO processes. Does it need API calls. Frame out the solution, all its requirements THEN decide on a medium to produce it on.

Uh, and just for clarification ASP.Net IS a Website solution. Just like ASP is, but for DotNet instead.

I personally think having a webbase app that will only be running on my PC and using IIS that is not hosted somewhere else is tacky.
