RefelectiveReader issue

Hi all,
I have a simple question I am using the .net windows phone project along side my windows phone 8 project…but I am getting errors on reflective reader which are only 8 errors just need to understand how to fix:

Error	5	The call is ambiguous between the following methods or properties: 'Microsoft.Xna.Framework.Content.ContentExtensions.GetAllProperties(System.Type)' and 'Microsoft.Xna.Framework.Content.ContentExtensions.GetAllProperties(System.Type)'	C:\..\..\Desktop\MonoGame-develop\MonoGame-develop\MonoGame.Framework\Content\ContentReaders\ReflectiveReader.cs	38	30	MonoGame.Framework.WindowsPhone
indent preformatted text by 4 spaces

It is coming from the C:…\Desktop\MonoGame-develop\MonoGame-develop\MonoGame.Framework\Content\ContentReaders folder, just wondering if anyone has had this issue.

Actually here is a better question, do I really need that project in order to use Microsoft.Xna.Framework.Gamerservices?
