I have a web application that runs fine under IIS5 or IIS6. I just installed Vista, which has IIS7. I just copied the entire web app over as-is, no changes to any files. I went into the IIS7 manager and created a web appliction under the Default Web Site and pointed it to the app I copied over.
When I try to browse to the app in IE, it tells me there's nothing there to handle it and that directory browsing is not turned on. This is a .NET app, so it uses Default.aspx. I looked in the manager, and there was no handling of Default.aspx setup. Is that not on by default for IIS7?
So, I added Default.aspx, and now the error is "HTTP Error 404.3 – Not Found
The page you are requesting cannot be served because of the extension configuration. If the page is a script, add a handler. If the file should be downloaded, add a MIME map."
I thought maybe it was because the default for IIS7 is Integrated Mode, so I created a new AppPool for Classic Mode and changed my app to use that. I still get the same error.
I was under the impression that I could move .NET apps to IIS7 without any changes. Is this not true?

0) Check if you have asp.net extensions installed under Programs and Features - Windows Features - WWW services - Application Development Features - .Net Extensibility / ASP.Net
1) The Microsoft .net framework
2) Try copying the whole directory to your IIS's root folder (usually wwwroot), common error that iuser/iwam does not have rights to read the other folder.
3) Check under "Handler Settings" if you have .aspx associated with any Isapimodules.
