Namespace Reference issue

Hi Team,

      I am migrating from community version 11 to 12. In version 11 I used "using Telligent.Evolution.Extensibility.Remoting.Version1;" namespace to access  "public virtual string Url()" method there is no error there.

But when migration I changed Telligent.Evolution.Platform.dll to "12.0.2.17146" then my "using Telligent.Evolution.Extensibility.Remoting.Version1;"  is throwing reference error.

        [Url]
        public virtual string Url
        {
            get
            {
                return this.url;
            }
            set
            {
                this.url = value;
            }
        }

Kindly help me to over come this error and access the "public virtual string Url()" methid
