WCF Client not able to see Custom Fault Exception

Question

as you can probably make out from the question title that I am new to WCF. I have implemented this web service and one of the methods throws a custom FaultException.

namespace Feed
{
    [ServiceContract]
    public interface IMyClass
    {
        [OperationContract]
        [FaultContract(typeof(CustomError))]
        DataSet MyMethod(int A, int T);
    }
    [DataContract]
    public class CustomError
    {
        public CustomError(string msg, int code, int id)
        {
            Id = id;
            ErrorMessage = msg;
            ErrorCode = code;
        }
        [DataMember]
        [DataMember]
        public string ErrorMessage
        {
            get;
            set;
        }

        [DataMember]
        public int ErrorCode
        {
            get;
            set;
        }

        [DataMember]
        public int Id
        {
            get;
            set;
        }
    }
}

Then, I throw the proper exception in the implementation of MyMethod

namespace Feeds
{
    public class MyClass : IMyClass
    {
        DataSet MyMethod(int A, int T)
        {
            try
            {
                //todo
                DataSet ds = new DataSet();
                return ds;
            }
            catch (Exception ex)
            {
                throw new FaultException<CustomError>(new CustomError("a", 1, 0));
            }
        }
    }
}

So far so good. Now I created a simple ASP.NET website which consumes this web service. I added a WebReference in that website for the MyClass.svc web service. Problem is that when I'm trying to catch the exception: catch(FaultException ex) { } it is not able to recognize CustomError. I have done the following troubleshooting: 1. Ensure I have the wsdl updated (done numerous time, tried changing other things, everything is reflected on the client side) 2. Tried BasicHttpBinding as well as wsHttpBinding (not sure if that makes a difference) 3. Googled alot and followed sample code from MSDN religiously.

Still no luck! Am I missing something? Any suggestions will be greatly appreciated.

Found out what the problem is.
My ASP.NET website was on .NET Framework 2.0 (which is what VS 2010 does by default), and I was adding the reference to the web service by right-clicking the project and selecting "Add Web Reference..".
However, what I needed to do what, select "Add Service Reference.." to add the web service as a service reference. Since .NET 2.0 does not support service references, I had to upgrade my .NET framework to 3.5, add the service reference and everything worked like a charm! This post lighted the bulb in my mind. Thanks everyone for all the effort put into this.
