How to create a single WSDL file from existing WCF service?

Question

How do I create a single flat WSDL file (with no external references from within) from an existing WCF service? This WSDL will be used (imported) into an older programming t

Answer 1

I had to do this, too. And I used the WSDLExtras library. It's not too big of a deal.

Here is a step by step instruction for using it:

1. Download the WCFExtras from here, extract it and add a reference to it in VS.

2. Add a reference to your Web.config/App.config like this:

   <system.serviceModel>
       <extensions>
           <behaviorExtensions>
               <add name="wsdlExtensions" type="WCFExtras.Wsdl.WsdlExtensionsConfig, WCFExtras, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null" />
           </behaviorExtensions>
       </extensions>
   </system.serviceModel>
   

3. Add the extension to your endpoint behavior and set the singleFile attribute to true

   <endpointBehaviors>
        <behavior name="singleFileEndpointBehavior">
            <wsdlExtensions singleFile="True" />
        </behavior>
   </endpointBehaviors>
   

4. Use the endpointbehavior for your service-endpoint.

   <endpoint address="YourEndPoint/Address" binding="YourBinding" behaviorConfiguration="singleFileEndpointBehavior" contract="IYourContract">
   

This worked fine for me. You can also download a full example from the WCFExtras project page: ProjectPage

Edit: For the sake of completeness: You can use the ''?singleWsdl'' query parameter since .NET 4.5 as stated in Irwins answer. See the link he posted for more details.

Answer 2

You can now do this natively in .net 4.5 (beta). There is an option (?singleWsdl instead of ?wsdl) for telling the service to output everything in a single wsdl document. More info on the new stuff here: http://msdn.microsoft.com/en-us/library/dd456789(v=vs.110).aspx
