David Betz describes in his article how to create reference to WCF without using “Add Service Reference” option:
http://www.netfxharmonics.com/2008/11/Understanding-WCF-Services-in-Silverlight-2

Once WCF service is created, these are the statements within the silverlight:

  BasicHttpBinding basicHttpBinding = new BasicHttpBinding();
  EndpointAddress endpointAddress = new EndpointAddress("http://localhost:1003/Person.svc");
  IPersonService personService = new ChannelFactory<IPersonService>(basicHttpBinding, endpointAddress).CreateChannel();

…

How does one references the types (such as IPersonService interface) created in WCF from Silverlight when I do not use “Add Service Reference” to buid proxies?

    Idea is to reference assemblies that contain WCF data contracts in silverlight application, and to do that you need to fool VS so it thinks assembly is a SL assembly, he describes this in detail here

    http://www.netfxharmonics.com/2008/12/Reusing-NET-Assemblies-in-Silverlight

    and its not so easy, here is what needs to be done

    Just use the same ILDasm/Edit/ILAsm
    procedure already mentioned to tell
    the assembly to use the appropriate
    Silverlight assemblies instead of the
    .NET assemblies. This is an extremely
    simple procedure consisting of nothing
    more than a replace, a procedure that
    could easily be automated with very
    minimal effort. It shouldn’t take you
    much time at all to write a simple
    .NET application to do this for you.
    It would just be a simple .NET to
    Silverlight converter and validator
    (to test for assemblies not supported
    in Silverlight). Put that application
    in your Post Build Events (one of the
    top 5 greatest features of Visual
    Studio!) and you’re done. No special
    binary hex value searching necessary.
    All you’re doing is changing two well
    documented settings (the public key
    token and version).

    Second solution is a file level solution , you use add link option on files that contain your required data contracts implementations to SL and make sure they only contain types that allow to build SL and dont reference a lot of external assemblies , usually those conditions should be met for WCF services & data contracts.

    I can write more but it would be just the copy paste from that link
