My setup:
Vista 64-bit PC (my local PC) IIS 7 obviously VS 2008
I setup a new "Application" manually under the IIS default site. It's running. The application is pointing to the correct directory (where my default.aspx exists) I've setup this same exact setup on our dev server running Server 2008 and it runs fine
But for me, when I go to http://localhost/MyAppName I get a 404 not found.
I have no clue why.
So since that did not work and still got a 404, then I tried instead changing from using the VS web server to using IIS in my web project properties in the "Web" tab in VS 2008. Then clicked the "Create Virtual Directory" button and it created a new Application in IIS for me. Same thing though. If I go to that address, I get a 404 on my local machine where it's running.
