I’ve set up IIS 7 on my Windows 2008 R2 server according to this guide and deployed my ASP.NET MVC application on it via the one-click publishing method in Visual Studio 2010, but the IIS server fails to run the application due to a configuration error:

Add the following references to the project:
Set the property Copy Local to True for the following references:
ITHedgeHog made me aware of a shortcut in Visual Studio 2010 for the above procedure:
Right click on the project and click Add Deployable Dependencies, you will then get a dialog in which you can simply pick ASP.NET MVC.
