I'm troubling into an issue...
I'm trying to find a way to generate a single wsdl document from my WCF service, i.e. without any link to external documents.
I've used FlatWsdl to remove all xsd:import links, bou my generated wsdl still contains a link to an external wsdl document via a wsdl:import declaration:
<wsdl:import namespace="http://myurl/mynamespace"
location="http://myserver/myservice.svc?wsdl=wsdl0"/>
This document actually contains all inlined xsd schemas, so... there's a way to inline also this external wsdl document, in order to have a single wsdl?
Thanks a lot for any kind of help.
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
(EDIT: Previous answer about FlatWSDL deleted, because as you pointed out it was about eliminating xsd:import not wsdl:import.)
Look at this blogpost: Control generated WSDL in WCF
"... There is always one WSDL generated for one target namespace URI ..."
Do you have different namespace for ServiceContract, DataContract, ServiceBehavior, etc. ?
You could also use the WCFExtras project it has an extension to create a single WSDL-file.
WCFExtras
A collection of useful WCF extensions
including Soap Header support, WSDL
documentation and more.
The WCF platform is very extensible
and allows you to easily add features
that are not part of the core product.
This project contains some extensions
I needed in a WCF based project:
SOAP Header support for WCF Adding WSDL
Documentation from Source Code XML Comments
Override SOAP Address Location URL
Single WSDL file for better compatibility with older SOAP tools.

my problem was in endpoint definitions, that are in tempuri.org namespace
adding bindingNamespace to endpoint declarations fix my problem.
thanks to all for help :)
This is a late answer, but I had the same problem with a few of our WCF services. If you're on .NET 4.5, like the earlier answer, use ?singleWSDL, but if you're not targeting .NET 4.5 then I added the following to my web.config to fix the issue...
<useRequestHeadersForMetadataAddress>
<defaultPorts>
<add port="80" scheme="http" />
<add port="443" scheme="https" />
</defaultPorts>
</useRequestHeadersForMetadataAddress>
This goes in your behavior. That way I didn't have to flatten the WSDL because all references were to MyURL instead of MyServer.
Hope this helps others with a similar issue.
In addition to Jim's answer above, if you're using C# code to configure a WCF ServiceHost directly:
using System.ServiceModel.Configuration;
and when setting up your ServiceHost:
UseRequestHeadersForMetadataAddressBehavior urh = new UseRequestHeadersForMetadataAddressBehavior();
serviceHost.Description.Behaviors.Add(urh);
I struggled to find this information online, as simple as it is. Hopefully helps someone in a similar situation.

I created a web service within my MVC application. All contracts are using the same namespace. AssemblyInfo.cs also maps the ContractNameSpace with ClrNameSpace.
The generated WSDL does not define my contract types.
This is my second project with ServiceStack. However, the results are different.
Does contracts have to reside in a different assembly in order to ServiceStack to generate WSDL correctly?
The issue was fixed in the latest ServiceStack release: https://github.com/ServiceStack/ServiceStack/issues/306
Make sure you're not using a dodgy tool like WCFStorm. I was getting the same issue even with the current ServiceStack release. I switched to soapUI and everything works expected.
The Types in the WSDLs and XSDs are determined by the Request + Response DTO's used in your services, i.e. they need to be used by your services to be included.
Also be sure to read through the SOAP limitations to make sure there isn't anything you've missed.
If you still think it's an issue, submit an stand-alone project, via gist or pull-request that shows the issue.
Your question is identical to the issue I was having so I'll post my solution here:
I've downloaded the source code and done some investigation on my own. I'm not sure how recent this change is but it appears that in order for your DTO's and Response objects to be included in the wsdl you need to add a query string like "?includeAllTypes=true".
I'm also using the ServiceStack BasicAuthProvider setup which is causing AssignRoles and UnAssignRoles to be added to the Service automatically. The request and response objects for those calls are still failing to make it into the wsdl and causing "Add Service Reference" to fail. Fortunately we aren't making use of them so if I can find another configuration setting to remove them all should be working correctly.
I have been following along with the Aaron Skonnard videos on creating a WCF service. I have completed the tutorial found here and when finished the WSDL page that would normally be available to a consumer of this service is not found (page states that "Endpoint is not found").
I have found many references to this issue including adding a 'mex' endpoint, adding httpGetEnabled, etc. but nothing seems to work. I believe this is because the tutorial removes the service files from the website code behind and instead uses a reference to another project.
I like the way the service is created with this tutorial but need to know how to get this WSDL page to display properly so others can consume my service. Is this no longer the correct way to create services in .NET 4?
I don't think REST based services (WebAPI) create a WSDL at all. I beleive the WSDL is only for the SOAP based WCF services.
This might be a really stupid question, but I've been unable to figure out a solution.
I have a WCF service hosted on a site that uses SiteMinder authentication. The authentication relies on a cookie in the client request.The problem is that when I try to generate a proxy class using svcutil, the operation fails because when svcutill tries to get the metadata, it obviously doesn't add the SiteMinder cookie to its request.I was therefore wondering if there was a simple way to generate the WCF service proxy class programatically.
If you have access to the compiled service DLL file, you can use the SvcUtil command line utility to generate the WSDL and associated XSDs for the data contracts. The main wrinkle with this approach is you'll need to add the name of the XSD file generated by SvcUtil in each xsd:import element in the schemaLocation attribute value.
Below are samples of modified xsd:import elements. For the "http://tempuri.org/" namespace, I added the schemaLocation attribute with the value of "tempuri.org.xsd" to let the Add Service Reference process know to look for that file in the same folder as the WSDL file. If your WSDL uses wsdl:import instead, add a location attribute instead of a schemaLocation attribute. This related question and answer should give a good start.
<wsdl:types>
<xsd:schema targetNamespace="http://tempuri.org/Imports">
<xsd:import namespace="http://tempuri.org/" schemaLocation="tempuri.org.xsd" />
<xsd:import namespace="http://schemas.microsoft.com/2003/10/Serialization/" schemaLocation="schemas.microsoft.com.2003.10.Serialization.xsd" />
</xsd:schema>
</wsdl:types>
EDIT:
Generating the client code using the compiled service DLL requires a two step process. SvcUtil needs the service WSDL to generate the client. It cannot directly use the compiled DLL.
First generate the WSDL using the DLL that contains the ServiceContract. I think you can use the service implementation file if the service contract DLL is also in the same folder.
cd "\Path\To\Your\Service\DLLs"
svcutil YourService.DLL
This will create several files depending on your service structure. There'll be one .WSDL file and several .XSD files. Edit these files as shown above.
Lastly, either use the Visual Studio Add Service Reference dialog to select the edited .WSDL file (just enter the full path and file name) to generate the client code or use SvcUtil as follows:
svcutil *.wsdl *.xsd /language:C#
It is just magic that I put some file in my site's Bin folder and place a svc file to point to some assembly pointing to my service type. And then, I could magically Add Service Reference to the url like this:
http://www.myserver.com//xxx.svc
I really want to know how what happens from my click "Add Service Reference" to the proxy is generated properly. What does the IIS do during this period?
It's not really magic - it's metadata exchange ! :-)
When you do a Add Service Reference in Visual Studio, behind the scenes, that service endpoint specified by the svc file is interrogated for its metadata. This is basically similar to a WSDL (Web Service Description Language) file - a machine-readable description of your service, its methods, what parameters they expect etc. - and a XSD (XML schema) that - again in machine-readable form - defines the parameter types used.
Based on those two pieces of information, the WCF client side import can create C# or VB.NET classes that
mirror the exact service implementation on the service side - same method names, same parameters expected and returned
create the necessary data classes - again in C# or VB.NET - based off of the XML schema file
So in the end - it's really not magic. It's the beauty of self-describing services and a bit of code generation that reads that metadata and creates client-side proxy classes from that metadata description
If you're interested in more details about metadata, read the MSDN docs on WCF metadata - quite extensive and in-depth.
As marc_s stated, the "Add Service Reference" button runs a tool that collects the metadata from the service, and generates client code from it.
I just wanted to add that if you want to view that metadata (WSDL) yourself, you can just add "?wsdl" to your URL:
http://localhost/MyService.svc?wsdl
One WSDL document will chain to many others, so you would have to make several requests to dig through them all, but it is interesting to see how the data types and contracts are transmitted.
Also, if you want to prevent other people from automatically generating a client to your service, you can disable the WSDL by removing the "mex" (Metadata EXchange) endpoint from your WCF configuration.
I have a wcf web service and I need to provide the client with the wsdl files.
Previously I used svcutil on the .dll and everything was fine.
However, recently I implemented the factory to Flaten the wsdl file (re: http://wcfextras.codeplex.com/).
My questions is this: Is there anyway of either using svcutil on the .svc to extract the Flattened .WSDL files or maybe somehow hit up the web service when it is running in the local webdev server to retrieve the .WSDL files?
As far as I'm aware, if I was to navigate to my local web dev server (http://localhost:2916/Service.svc?wsdl) and if i was to view source and saved that as .wsdl that this is wrong and would not provide all the relevant information.
note: See below for how the Factory is used in the .svc file....
<% #ServiceHost Factory="CompanyName.ServiceModel.Extensions.Description.FlatWsdlServiceHostFactory" language=c# Service="CompanyName.WebServices.Service"%>
Thanks,
Steven
Yes, you should still be able to use svcutil to extract the WSDL from your service, even if you have an extension installed that will flatten the WSDL.
To download the metadata document(s) from your running service, use this command:
svcutil /t:metadata http://service/metadataEndpoint
You need to point your URL to the metadata endpoint defined in your config, e.g. the endpoint that's defined to use "mexHttpBinding" or "mexTcpBinding" and the "IMetadataExchange" contract.
If you don't have any metadata exchange endpoints defined, you won't be able to retrieve that information, obviously.
