Passing object through WCF so that server receives client changes

I would like to set up a WCF service so that any changes a client makes to an object I send them are also 开发者_C百科reflected on the server side. For example, if Assembly A has the following...

namespace AssemblyA
{

    public class Person
    {
        public string FirstName { get; set; }
        public string LastName { get; set; }
    }

    [ServiceContract]
    public interface IServer
    {
        [OperationContract]
        Person GetPerson();
    }

}

And Assembly B references Assembly A...

using AssemblyA;

namespace AssemblyB
{
    class Program
    {
        static void Main(string[] args)
        {
            <snip>
            IServer server = factory.CreateChannel();
            Person person = server.GetPerson();
            person.FirstName = "Kilroy";
            person.LastName = "WuzHere";
        }
    }
}

What is the easiest/best way to make it so that the service's copy of the Person object also reflects the changes that the client makes? Is this even possible?

Create a method on the server which take a Person object as parameter.

[ServiceContract]
public interface IServer
{
    [OperationContract]
    Person GetPerson();

    [OperationContract]
    void UpdatePerson( Person person )
}

and call that from the client after you have set the FirstName and LastName properties.

server.UpdatePerson( person );

If you are in need for handling events between the client & server, you ought to look for Duplex Contracts with WCF. This is a very good detailed example for you to start with: http://www.codeproject.com/Articles/491844/A-Beginners-Guide-to-Duplex-WCF
