As you mentioned you can access your service by. In the IIS 6 The cause of this error must be Check that file exists setting of svc extention, make sure "Check that file exists is unchecked". On production, however, I can reach service. Both environments are hosted in IIS 7. I've enabled tracing and the service isn't even picking up any of the method requests e. Below is the system. The SSLBehave was suggested from here. I had the same problem. The first thing I do whenever I hit a with a newly-developed WCF Web Service is checking the handler mapping required to interpret this type of call, because it's often the cause of the issue.

There are several ways to work around the problem, many of which require a manual execution of the ServiceModelReg. The resolution method I propose below is slightly longer to pull off, but has the advantage of solving the problem more safely and securely.

Once the installation is complete, you should be able to run your WCF Service without incurring in the error ever again. For additional info regarding this specific issue and how to fix it, you can also read this post on my blog.

WCF service returning on method requests 4 As you mentioned you can access your service by. UrlRoutingModule, System. Also note that the production server is hosting multiple sites within IIS. I had to add this to my config file for the WCF service web.

Assuming you are using.

NET 4 your service will be listening on one or more endpoints using basicHttpBinding - this is the default if you don't specify an endpoint when using HTTP. The easiest way to achieve this is to build a proxy using Add Service Reference in a client project and make calls through the generated proxy class - the WCF plumbing will generate the appropriate message and POST it to the service.

I think it would be more useful to view it as "retrieving the metadata works but making a service request fails with a ". Also, how many service contracts does your service implement? My service implements 1 service contract with about 10 operations. In the WSDL what is the address of the service?

Are you getting something in there that is not routable from the client? Sign up or log in Sign up using Google.I have an Apache webserver configured in reverse proxy mode which listens for requests on a public IP address and serves them from the internal IIS host. Is there any setting that can be configured in wcf application's web.

I'm having similar issues, one of which was the resolution of public and server addresses.

This solved that issue although I still have a couple authentication problems. See this answer for how to create an extension to allow AddressFilterMode. Any to be specified through configuration without requiring code attributes.

In the web. In the same endpoint element, set the listenUri attribute to the absolute URL on which the service host is listening. The way I determine what the default absolute URI the host is listening on is is to add a service reference in a client application which points the the physical server where the service is hosted.

The web. I then copy that into the listenUri attribute in the hosts web. I am not sure if this works with message security or transport security. Since the transport is secure to the ssl load balancer there were no security issues. Unfortunately, there is a bug in WCF where the the base address of imported schemas in the WSDL have the listenUri base address rather than the public base address the one configured using the address attribute of the endpoint.

To work around that issue, you need to create an IWsdlExportExtension implementation which brings the imported schemas into the WSDL document directly and removes the imports. Additionally you can have the example class inherit from BehaviorExtensionElement and complete the two new methods with:.

This will allow you to add an extension behavior in the. And then reference the new endpoint behavior in your endpoint configuration using the behaviorConfiguration attribute. It is also possible in to leave the listenUri attribute blank, however it must be present.

I would start by checking a number of things; Permissions on the hosted directory? Net version is correct? Have you added the certificate to the site? Try putting an image in the same path, can you navigate to that rule out the odd occasional path mappings Good luck!

The only difference is that he was at least able to get the AutoCompleteExtender to communicate with the WCF service when they were both in the same project. I can't even get that far.

It is also worth noting that my ultimate goal is to deploy the solution to a SharePoint site which is why I'm restricted to an older version of the AjaxControlToolKit and. NET framework 3. However, as of now I can't even get the code to work when I create a brand new website that is completely independent of SharePoint along with the WCF service hosted in the same site so I can avoid any Same Origin Policy issues that might prevent any of this from working.

I was able to get a jQuery autocomplete solution working using the exact same WCF method but for the purposes of this project I cannot use jQuery. This must be a pure C.

NET solution. I have already exhausted all the regular suggestions, including:. All of the required HttpHandlers in the web. I'm all out of ideas. The only thing I can think of is that since I'm performing all of this work on a server that has SharePoint installed that maybe the SharePoint installation made some wonky configuration changes to IIS that is secretly screwing everything up.

I haven't had a chance to try this on a pure machine that doesn't have SharePoint installed but that is likely going to be my next step. Just to reiterate, although I ultimately want to get this working in a UserControl deployed as a SharePoint solution, at this point I can't even get the autocomplete working in a standalone web application that is completely independent of SharePoint, running on the same physical server as SharePoint but as a separate website using a totally different Application Pool.

Now while I don't have much faith in people who provide solutions to problems that involve leaving out things like interfaces because they don't know how they work I don't think the dude would take the time to post something technical like this, claiming that it's possible when it really isn't. And since he was kind enough to try and share whatever knowledge he gained from his experience it would be pretty ungrateful and kind of jerky for me to knock him for not knowing something at this point.

Finally some progress! Now I know that this won't be possible for my real solution because this won't work on UserControls which are my only option when it comes to SharePoint. But still, after all this time I was just so desperate that I needed to see something work. It still didn't work! Yeah, you heard that right. The only difference was that the error said: "Unknown web method GetItemsList. Parameter name: methodName" Crazy, I know. So I start digging around the web a little more and that's when I stumbled upon this fun little discussion on how to get AutoComplete to work without using a web service.

Now keep in mind that I had already read like of these types of posts before but something about this one was different. In this post the code was using static methods. I figured what the hell.

That did it.

Service Operations (WCF Data Services)

I had finally gotten AutoComplete to work. The only problem was that I couldn't make my WCF service methods static. So now what? Back to the drawing board So there I was. After finally tasting success for just a few brief seconds my hopes were quickly dashed once I realized that this wasn't really going to help me at all.

Well, at least I got AutoComplete to work in some capacity right? Yeah, this wasn't going to cut it. There had to be something else I was missing.Last post Sep 04, AM by mike4u. This is happening to me when running from Visual Studio There were some posts similar to mine but the users were not including the servicename. All the function NOOP does is return the text passed as a parameter. SVC and this loads a page alright explaining how to test the service including things like svcutil.

I actually made the adjustments on my web config file and interface based on that post and they are very similar. The only different between the code on that post and my own are the fact that I dont have 2 service contracts, but as the author mentions is not a requirement and I would like to keep it simple with only one service contract. Perhaps the problem I'm having is the way I'm trying to test it through the browser?

Any aditional help is highly appreciated. I've replicated the simple calculator wcf project on the URL you provied as a project and when I run it I still get a resource cannot be found on the browser when I try to call the method AddRest throught the browser.

I have no idea what to do next and googling it isn't taking me anywhere. I wonder what I am missing. I also tried to publish the same calculator project to a local IIS 7 server and same behaviour.

Many thanks in advance.WCF Data Services enables you to define service operations on a data service to expose methods on the server. Like other data service resources, service operations are addressed by URIs. Service operations enable you to expose business logic in a data service, such as to implement validation logic, to apply role-based security, or to expose specialized querying capabilities.

Like all other data service resources, you can supply parameters to the service operation method. For example, the following service operation URI based on the quickstart data service passes the value London to the city parameter:. For more information, see How to: Define a Service Operation. For information on how to call a service operation from a.

The following requirements apply when defining service operations on the data service. If a method does not meet these requirements, it will not be exposed as a service operation for the data service. The operation method may only accept input parameters. Data sent in the message body cannot be accessed by the data service.

If parameters are defined, the type of each parameter must be a primitive type. Any data of a non-primitive type must be serialized and passed into a string parameter. The method must be annotated with the [WebGet] or [WebInvoke] attribute. Other WebInvokeAttribute methods are not supported. A service operation may be annotated with the SingleResultAttribute that specifies that the return value from the method is a single entity rather than a collection of entities. This distinction dictates the resulting serialization of the response and the manner in which additional navigation property traversals are represented in the URI.

For example, when using AtomPub serialization, a single resource type instance is represented as an entry element and a set of instances as a feed element. You can address service operations by placing the name of the method in the first path segment of a URI. When calling a service operation, parameters are supplied as query options.

Additional path segments or query options may be added to the URI depending on the return type of the service operation. For example, the following line of code in the data service definition enables access to the CustomersByCity service operation.

If a service operation has a return type that has been hidden by restricting access on the underlying entity sets, then the service operation will not be available to client applications.

We recommend that you use the DataServiceException class whenever you raise an exception in the data service execution. This is because the data service runtime knows how to map properties of this exception object correctly to the HTTP response message.

Accessing the Service from a Web Browser (WCF Data Services Quickstart)

When you raise a DataServiceException in a service operation, the returned exception is wrapped in a TargetInvocationException. Skip to main content. Exit focus mode. Service Operation Requirements The following requirements apply when defining service operations on the data service.

SOAP Requests with Postman

The operation must be a public instance method that is a member of the data service class. A primitive class such as integer or string. Addressing Service Operations You can address service operations by placing the name of the method in the first path segment of a URI.
