Determining if an app is a web app or a windows app

Hi all,

 I'm writing a generic utilites class and one of the methods needs to get the physical path of the application.

I know Server.MapPath("~") gets the server path of the app for windows and also that Application.ExecutablePath gets the path for windows app.

Now how would i determine which app is a windows app or a web app?

 

Thanks in advance.
