i have a wsdl file, now i need to get the original wcf service. and after that i want to use(consume) that service in my web project.
please tell me is this possible? and how?
The WSDL contains only the definitions of the service contracts and data contracts. Don't expect to reconstruct the implementation of the original service from a WSDL file. In order to generate a client proxy which will allow you to call the service given this WSDL you could use the svcutil.exe utility.

I use a wsdl file to generate web service with the help of svcutil but it generates class instead of simple int or string parameter for the service contract.
What I did:
I created a WCF Service Application
I created a Console Application then added the service reference to the project
I used svcutil.exeto generate service from thy wsdl and xsd files in console project
Why does it do that and how I can rewrite the wsdl to solve this problem, please?
Most likely you used /messageContract switch in svcutil.
If you added service via service reference, then right click on service->configure service reference and uncheck Always generate message contracts
is it possible with SAP to generate client stubs and transfer objects from a WSDL served by a .NET WCF web service? Or do I have to build my SOAP XML requests manually?
To be more on the point. I still have a WCF web service and the wsdl. I have no knowlege in SAP. So the question is. Is it possible and how can I create client service stubs and the transfer objects in SAP from my WSDL?
It's easy to create an ABAP client for an existing web service if you have access to the URL for obtaining the wsdl file or the wsdl file itself. See this link for an step by step tutorial wich is basically:
1- Generate proxy from wsdl using assitant
2- Use proxy generated in your ABAP program

You can use the WSDL from the wcf for this. You can get the WSDL as service.svc?wsdl. However at times, some SOAP client generator expect all the definitions of the SOAP/WSDL in a single call. For that you might have to look at the following pages:

WCF: how to generate a single WSDL document, without WSDL:import?
Do you know if there is any way to access the wsdl file when you create a WCF service library? It seems you can get it when you create a WCF application but not the service library...
Any ideas would be appreciated.
Thanks
The only way to access the WSDL is once you host and run the service. Otherwise, you cannot access it. So, create a host (or application as you are calling it) with a mex binding, then run the service and you should be able to access the WSDL.
Once you do this, you can save the WSDL as a file or something for later reference.
You cannot access the WSDL automatically. Of course if you compile the static WSDL into the service library, as a resource, you could then access it directly.
but what is it that you are trying to accomplish?
The "Service Description" is available inside a service. It is not the WSDL itself, but rather, the in-memory model of a service description. It includes the namespaces, the element names and types - everything in a WSDL, and more.
You can get at it with System.Web.Services.Description.ServiceDescription. Typically this is done within a ServiceHost, a ServiceHostFactory, or an IEndpointBehavior.
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,

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.
I want to invoke a wcf service for testing on the http layer. I do not want to add a service reference and create a proxy and invoke. I want to create a new web test(VSTS) which sends a http request to the service and posts(Http post) the request in http body as an xml.
I have service metadata, with which I can see the datacontracts, but the wsdl:operation has only the operation name, wsdl:input is just blank.
On the Contary, an asmx service will have the soap request in the metadata which can be copied as the http request body, with the parameters replaced.
How to build a wcf service xml body from scratch just by looking at the service metadata (no access to the service logs as well), have got just the end point.
It is something like
<root>
<element1>element1</element1>
<element2>element2</element2>
</root>
But, how to find out this, root has to be some thing like
<FunctionRequest xmlns=""http://schemas...."" xmlns:i=""http://www.w3.org/2001/XMLSchema-instance"">
(tested for a local service and worked)
Now, without having access to service logs(svctraceviewer logs), not able to add a service reference, not able to use svcutil.exe(certificate based service), just only with metadata - wsdl, is there a way to find out the request that is to be sent to service?
Well, you will have to create proxy - either statically by adding a service reference or running svcutil on your service metadata, or you can construct it dynamically totally in code, if you wish.
In that case, you'd have to have your service contract (ISomethingService) at hand, and check out the ChannelFactory < ISomethingService > () concept - that should get you started.

Yes you can, but you have to do a little work first.
Build the service client by running svcutil.exe on the wsdl/xsd metadata. This will generate a c# with your service and data contract objects. Compile that to an assembly using csc.exe.
See the soap envelope body you can create a request object and manually serialize it with data contract serializer. Or you can host the assembly in WcfSvcHost.exe and add wcf logging to the config file. In either case you will only have the correct xml for the body, and even that might be wrong if the real service uses xml serializer instead of data contract serializer.
The next part is the hard part because you need to know the security model for the real service. If it only uses certificates for SSL and server identification, you should be able to send the xml using WebClient. But if it uses mutual certs and/or security tokens, you pretty much have to create a channelfactory by hand with the right bindings.
