I have consumed several wsdl services successfully, but am stuck now with this web service.
Am implementing Hotelston webservice which state :Hotelston.com API is a standard SOAP Web Service (WS) available at URL
http://www.hotelston.com/ws/HotelService?wsdl
I cant access the direct code of the webservice after i added the it as a reference in my application.
Please see the following MSDN articles for the exact details on how I added and used these web service references but still cant access it from the direct code.

If you show all files in the project and expand the service reference out, Reference.cs is empty. This is likely because there are namespace errors in HotelService.wsdl ("ax23", specifically) that is causing the t4 template to fail to generate the service code. Bottom line, it's their fault, not yours.

We have an existing wcf service, and I created a new project. I want to use it. I hit add service reference, pop in the URL, press OK, and it adds it as a service reference but there is no config generated.
I also tried svcutil.exe /language:cs /out:GeneratedProxy.cs /config:app.config [url] but no config is generated, only the proxy cs.
I'm using VS 2013 / .NET 4.0
My question is, is this a sign that the SVC itself has some missing data that is required to build the contracts, or is the problem with adding the service reference?
For the record I have tried unchecking the reuse types option which some questions on here have reported as fixing the problem.
Bonus question, do you think if I can't get this working that manually adding some generic default bindings and endpoint code to the web config will work?
First, the reason that why the Adding service reference generates nothing is that the WCF service is rest style service. By default, the proxy-based invocation of rest style WCF services is complex.

https://learn.microsoft.com/en-us/dotnet/framework/wcf/feature-details/wcf-web-http-programming-model
Calling the WCF rest style service with the client proxy is uncommon. Generally, we construct an Http request by using an HTTP client library to call the service, such as HttpClient, WebClient.

Besides, calling the WCF rest style service with the client proxy is feasible. Please refer to my previous link.
WCF: There was no endpoint listening at, that could accept the message
Feel free to let me know if there is anything I can help with.
I have created a WCF service using Service Library template. Using the Service.dll generated, I have hosted the service in a console application.
However, when I add a Service Reference in my web project, on viewing the Service details in Object browser, it points to incorrect assembly in the object browser as shown in the screen shot below.
One possible issue could be that, while renaming the namespaces in my web project, I ended up renaming the namespace of Service project also. But even after fixing all the namespaces, I still have this issue.
Any ideas on what can be done to resolve it?
While adding a Service Reference, it displays the correct members/interfaces as shown in the screenshot below. Only when I view the Service Reference in the object browser, I don't see those interfaces exposed by the service.
Project dependencies of service project
Not sure why the web project is a dependency of the Service library project? It should not be as I have not added any reference to it in the Service project.
I came across this question here after researching on this issue.
I also found out that the reference.cs file was empty in my case also. After unchecking Reuse types in referenced assemblies from 'Configure Service Reference' dialog, I was able to generate the Service reference client code successfully. My Service reference is now pointing to the correct Interface/members. In case of any queries, feel free to comment or contact me directly.
I am using Biztalk UDDI V3 (stand-alone install) on a windows 2008. I have configured all services (web, database and subscription):
I successfully published a couple of services
I successfully accessed and retrieved service information from my .net console application.
My issue at this point is with the subscription service. I tried to subscribe to one of the published services only to find out that I need to create my own listener.
I followed the steps listed here. Please take a look at the section entitled "Building subscription alerts for service changes". I am confused as to what the WCF service I create is supposed to look like. The instructions state the following:
Now we create a new WCF Service project and reference this existing service library. After making sure the .svc file points to our referenced library object, and adding a valid endpoint configuration file, view our service in the web browser to ensure that it's up and running.
I find this section confusing. Not sure what public methods would the WCF service expose(if any at all) or how to expose the functionality within the service library that I just referenced from within my WCF project.
Of course, if you know of a different way to achieve what I am trying to accomplish, that also would be much appreciated.
Thank you.
This may help. I actually just wrote a complete port for Apache jUDDI's client library using .NET C#. One of the use cases is actually what you are attempting to do. Here's the rough approach used.
Generate the code from wsdl (using wsdl.exe, because svcutil doesn't like the UDDI wsdls)
Alter the interface code to have WCF bindings for the Subscription Listener class
Create an implementation of the subscription listener and handle the callbacks
Fire up the implementation using WCF's embedded service
Register your sub listener endpoint with UDDI (using the correct annotations per the spec)
Setup the subscription using your sub listener's binding template
Wait for callbacks
Here's the code
http://svn.apache.org/repos/asf/juddi/trunk/juddi-client.net/
Example
http://svn.apache.org/repos/asf/juddi/trunk/juddi-client.net/juddi-client.net-sample/org.apache.juddi.client.samples/SubscriptionCallbackExample.cs
There's also a Java version that does the exact same thing.
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.
We have a web service that is called when user clicks save button on web form. The 'save' web service then makes a call into another web service (different machine). The call always fails and as far as I can tell does not even attempt to cross the network because the Fiddler traffic is empty. This problem only occurs when we call the second web service from the first web service. If we call the second web service straight from the client or on page load, it works. We are using WebHTTPBinding with REST type services.
I used the WCF trace to come up with the error 'Envelope Version 'EnvelopeNone (http://schemas.microsoft.com/ws/2005/05/envelope/none)' does not support adding Message Headers.', but I don't know how to resolve it.
Any suggestions?
Possible fixes:
Check #ServiceHost directive( in
. svc file) is set to
"WebServiceHostFactory" source
WebHttpBeahvior element is added in
the endpoint behavior source
Put ORDER information in the XML
schema Class source
Check that your Data Transfer objects are
serrializable source
Check if Skype installed and make sure it
doesn't overtake the port

Remove SOAP message header (it is not supported for REST
WCF) source
