Our Web Hosting and Plesk accounts support MVC3 applications by default, but our Classic Hosting accounts do not. For more information, see What type of hosting account do I have?
However, you can deploy ASP.NET MVC3 applications to Windows Shared Hosting accounts by copying certain assemblies to the bin
directory.
If you want to use an ASP.NET MVC 3 RC2 application with our Windows® Hosting accounts, you must use IIS 7 or 8, runtime version 4.0 with integrated pipeline mode, and then upload the required assembly dependencies.
