Separate project Web Api and HelpPage (MVC)

Is it possible to have a separate Web Api project and HelpPage (MVC) project? I tried by doing the following:

1. Create Web Api project and added some APIs
2. Enable output for XML documentation in Web Api project
3. Add post-build event in Web Api project to copy the XmlDocument.xml file to HelpPage project's App_Data directory
4. Install HelpPage from nuget in HelpPage project
5. In HelpPageConfig.cs file, uncomment SetDocumentationProvider line to reference to the xml documentation file

The problem I have is that the API list is empty. Any thoughts? Is splitting to two (2) project possible?

Thanks.
