I just setup an out of the box "W2K8 R2 Web" server and installed IIS 7 out of the box. Then I installed the .NET4 framework and ran "aspnet_regiis -i" command.
I created a site using .NET 4.0 Integrated app pool.
I created an MVC application using the default MVC project template, without modifying I compiled the project and deploy the files using (Publish) to the virtual directory.
I can pull the site up, but the styles are missing from the page and for some reason it routing to the /Account/LogOn?ReturnUrl=/
