MvcApplication3.Areas.HelpPage.XmlDocumentationProvider' does not implement interface member 'System.Web.Http.Description.IDocumentationProvider.GetResponseDocumentation

Hi,
I'm experimenting on a new WebAPI Solution and it builds fine initially. When I install the Install-Package SDammann.WebApi.Versioning package I get the following error on building:

Error 2 'MvcApplication3.Areas.HelpPage.XmlDocumentationProvider' does not implement interface member 'System.Web.Http.Description.IDocumentationProvider.GetResponseDocumentation(System.Web.Http.Controllers.HttpActionDescriptor)' C:\dev\Scratch\WebAPI\ControllerVersioning\UsingSDammannNuget\MvcApplication3\MvcApplication3\Areas\HelpPage\XmlDocumentationProvider.cs 14 18 MvcApplication3

I even get this with the "Install-Package SDammann.WebApi.Versioning -Pre" package
