Multiple actions were found that match the request in asp.net web api

I working on "Code Camper" sample SPA application. I am running the app on VS 2010 with MVC 4 installed. But I ran into problem with LookupsController.

Here is the error I got:

    "exceptionMessage":"Multiple actions were found that match the request: \r\nSystem.Collections.Generic.IEnumerable`1[CodeCamper.Model.Room] GetRooms() on type
 CodeCamper.Controllers.LookupsController\r\nSystem.Collections.Generic.IEnumerable`1[CodeC

I found the answer!

When you create a web api project, by default there is this line of code in global.asax.cs

WebApiConfig.Register(GlobalConfiguration.Configuration);

I removed it (as I saw from source code of codecamper) and now there is no problem any more! but I dont know why exatly
