ReadRawObject giving error

I am trying to convert an old XNA example to Monogame but I am having a problem with one of the methods. The one I have problem with is this one:

github.com

SimonDarksideJ/XNAGameStudio/blob/archive/Samples/RolePlayingGame_4_0_Win_Xbox/RolePlayingGame_4_0_Win_Xbox/RolePlayingGameData/MapEntry.cs#L144


        /// </summary>
        protected override MapEntry<T> Read(ContentReader input,
            MapEntry<T> existingInstance)
        {
            MapEntry<T> desc = existingInstance;
            if (desc == null)
            {
                desc = new MapEntry<T>();
            }
            input.ReadRawObject<ContentEntry<T>>(desc as ContentEntry<T>);
            desc.MapPosition = input.ReadObject<Point>();
            desc.Direction = (Direction)input.ReadInt32();
            return desc;
        }
    }
    #endregion
}

The error i get is: Specified method is not supported. Is it because the difference between XNA and Monogame the reason is does not work or have i missed something? I have copied it so it should be the same. The only thing I have changed is that it uses the MG content loader instead of a content project.
