How to package an ASP.NET WebApplication

Hi Forum,

I'm developing a ASP.NET WebApplication. Now I do not know how to package it. If I create an Installer for WebApplications via VisualStudio.NET, I can produce an installer package, but if I run the package, the installation process fails, if the virtual directory does not exist already.

What I want is, that the virtual directory is created by the installer, but how??? Should I use another installer projekt and add some own code or is there a better solution for this problem?
