We’ve recently started a Dot Net Nuke project, that required IIS 7.5, so we installed a test server on a local Win 7 workstation that we had available to do some basic development work prior to moving to a production environment.
We installed the the IIS server via the “Add Windows Feature” in Windows 7 control panel and got the server to run Asp.net 4 without a problem. The issue we ran against was that the IIS server was NOT serving any content such as images or CSS files.
