Silverlight 4 + RIA Services – Ready for Business: Exposing WCF (SOAPWSDL) Services

Continuing in our series, I wanted to touch on how a RIA Services can be exposed as a Soap\WSDL service.   This is very useful if you want to enable the exact same business logic\data access logic is available to clients other than Silverlight.    For example to a WinForms application or WPF or even a console application.  SOAP is a particularly good model for interop with the Java\JEE world as well. 


First you need to add a reference to Microsoft.ServiceModel.DomainSerivves.Hosting.EndPoints assembly from the RIA Services toolkit. 




Then you need to edit the endpoints section of the domainserivces config in web.config  file.  Below I am showing the SOAP and OData endpoints enabled. 


        <add name="OData"
             type="System.ServiceModel.DomainServices.Hosting.ODataEndpointFactory, System.ServiceModel.DomainServices.Hosting.OData, Version=, Culture=neutral, PublicKeyToken=31bf3856ad364e35" />
        <add name="Soap"
             type="Microsoft.ServiceModel.DomainServices.Hosting.SoapXmlEndpointFactory, Microsoft.ServiceModel.DomainServices.Hosting, Version=, Culture=neutral, PublicKeyToken=31bf3856ad364e35" />


Now, all you have to do is navigate in the browser to this URL:


Note the pattern is [namespace]-[typename].svc


And we get the very familiar WCF service debug page.

And if you really want to drill in, here is the full WSDL describing the service.



You are done on the server, now let’s look at how you consume that on the client.    For the sake of simplicity, I have created a new Console application.  Right click on the project and select Add Services Reference.



  1: var context = new DishViewDomainServiceSoapClient();
  2: var results = context.GetRestaurants();
  3: foreach (var r in results.RootResults)
  4: {
  5:    Console.WriteLine(r.Name);
  6: }


The code for query is very simple.  Line 1 creates the client proxy, line 2 does a synchronous call to the server. Then we simply loop through the results.




Updating the data is a little bit more interesting…    I need to create a ChanageSet that I populate with any updates. in this case I am updating just one value.  I also need to send the original value back to the server. 

  1: var changeSet = new ChangeSetEntry();
  2: var org = new Restaurant();
  3: org.ID = entity.ID;
  4: org.Name = entity.Name;
  5: entity.Name = "Updated:" + entity.Name;
  6: changeSet.Entity = entity;
  7: changeSet.OriginalEntity = org;
  8: changeSet.Operation = DomainOperation.Update;
  9: var updateResults = context.SubmitChanges(new ChangeSetEntry[] { changeSet });



And you can see the result of running this a couple of times:

For V1.0, this post describes the RIA Services story for WPF applications.  While it works, it is clearly not the complete, end-to-end solution RIA Services offers for Silverlight.   For example, you may want the full experience:  the DataContext, entities with validation, LINQ queries, change tracking, etc.  This level of support for WPF is on the roadmap, but will not make V1.  But if you like the RIA Services approach, you might consider DevForce from IdeaBlade or CSLA.NET which works for both WPF and Silverlight.   The great folks at IdeaBlade have offered me 10 free licenses to give out.  If you are interested in one, please let me know.

    Are we creating here a new endpoint to the service (soap), or just exposing the metadata of the format already used? If this is a new endpoint, then how can we just expose the metadata of the default message format?

  2. BradA says:

    @Yaron — Correct, this just exposes the metadata for the default endpoint so that any client can access it.  

  3. Ivan Bondy says:

    Hello Brad,

    I would love to have free license of DevForce for my development and experimentation.


  4. BradA says:

    @Ivan — Great, I got you connected!  You should hear something soon.

  5. GoldyTech says:


    Me too also intrested in Ideablade license. You can reach me on

    CSLA.Net == California State Library Association web site. 🙂

    Thanks for your awesome series(es) on RIA!

  7. BradA says:

    @Craig — thanks, fixed!

  8. John says:

    Brad, thanks for the continuing your posts.

    I’d love to have an Ideablade license also.  I can reached at

    My company already has a lot of existing WCF services.  Is there any easy way to expose those existing services as domain services, or would it require converting all of them to domain services (which realistically, we would never do because there are too many).  I would like to use the dynamic linq capability on our current services.

    Free licenses for DevForce, Count me in! Its always our goal at my company (A huge civil engineering firm) to create apps as a service and consume the service in a UI. Sounds like RIA services is the ideal for this if your using Silverlight, but WPF and ASP.NET won’t have all the fancy features. Hope this changes soon.

  12. David Folger says:

    I’d certainly be interested in a free license from DevForce if you still have any left. Thanks for the great article I was just looking for something like this the other day. dfolger[@]

    how can I switch from binary to text encoding?

  14. Nic says:

    We are currently updating our client application from a mix of and silverlight (for media playback) to a full fledge SL4 (w OOB) application. RIA services definitively makes for our authentication and consuming data much easier though updates and generation of new entities still remains a little tricky mostly with the desire to offer these capabilities in offline scenarios. Would definitively be interested in DevForce licenses if you have any left as was considering their product, at least to evaluate if it meshed into our current architecture.

    Thanks for insights and conversations at MIX10, great learning by osmosis. nicolai.siggel [@] replayedu . com

  15. Bryan Hinton says:

    If there are any licenses for DevForce left I would be interested as well – I have been following what Ward’s company has been doing loosely for a while and we have some WPF apps internally at my company that would benefit from taking advantage from similar solutions to what RIA Services currently is offering for Silverlight.  I can be reached at HintonBR at

  16. Sinan Guven says:

    Well, if there is any left, please count me in.  sguven [@] gmail . com

  17. JJ says:

    Nice post.  Would love to brush up my dev force skills on full license if you have one left.

  18. Steve says:

    Brad, I have questions here, as some of this described is  vague to me.

    ie. why are you showing adding the service reference to a console app vs. a Silverlight app ?  I don’t understand how console apps fit this topic/title ?

    Basically, are you trying to say that by adding those two lines to my Silverlight config file that it will turn my WCF service references into Domain Service calls ?

    Sorry, missing the big picture here Brad.  I’m highly interested in consuming wcf services and using domain service together, so I’m interested… but confused by this post  🙂

    email me if you want steven dot gentile at gmail dot com

  19. BradA says:

    @Ladislav  are you looking to switch to text for debugging?  if so, check out this post:

  20. BradA says:

    Wow — thanks for your interest in DevForce… I have given away all 10 of the license that they gave me.  If you got one of them, the DevForce guys should be contacting you shortly.  

  21. Craig says:

    Hi Brad,

    Is it possible to configure the exposed endpoint with other bindings, like with MSMQ, or with WS-i extensions like WS-Security, or policy?

  23. Hello Brad,

    I’m interested in an Ideablade license as well. You can contact me at manuelfelicio{at}gmail[dot]com.


  24. Rajesh says:

    well,so i have no reference Microsoft.ServiceModel.DomainServices.Hosting.EndPoints in my reference windows.How can i bring that reference

  25. Dima says:

    Hi, Brad!

    Is it possibly to consume default raw REST endpoint  like WCF service? I cann’t configure bindings 🙁 it would be very nice of you to expain how it can be achieved.

  26. Jon says:

    The soap endpoint for WCF RIA domain service didnot support "Include/Association", after generate the service reference, the object with "include/association" attribute cannot be generated on the service reference side. Any solution?
