I want to know how the wsdl is written in wcf.
As i know the proxy class serialize the data and form a soap message to send over network, in the same way , i want to know who writes the wsdl file and takes care of serializing results of a call.
The abstract ServiceHostBase class has a method called CreateDescription that will take your service and operation contracts as well as your fault and data contracts and turns those into a ServiceDescription. This is then further handled by a WsdlExporter and turned into a WSDL and XSD file. What gets output to the WSDL (and XSD) is available on the service class as the "service description" (property "Description") - it contains information about the endpoints, bindings, other config settings etc.
Have a look at the MSDN Docs for the WsdlExporter class. You can even customize this process, if you want to - see these blog posts for more info on that:

Flattening your WSDL
And have a look at the MSDN docs on:

I'm looking for a web service wrapper to convert my classes to web services. each class to a specific service and the type of instance management is "percall". are there any tools? Or are there any simple ways for this conversion?
for example this tool can add "service contract" attribute to classes and "operation contract" to public methods and also "data contract" to all inputs and output datas of public methods.
AFAIK that does not exist.
Web Services, with ASMX or WCF, are specific beasts. You cannot just take any class and make it a service. You need to define Data Contracts, Service Contract, an Operation Contract per method, etc.
Check out "Getting started with WCF" at http://msdn.microsoft.com/en-us/library/ms734712.aspx.
Good luck!
I have a Product Datacontract with a couple of Datamembers that are part of a WCF Service. I also serialise and store this Product Datacontract in my app using the DataContractSerializer.
Now, I want to remove some of the Datamembers of the Product Datacontract when the Service metadata (WSDL) gets generated. However, I want all Datamembers from the Product Datacontract to be available when I serialise the object within my app.
What I wanna do, actually, is this: grab hold of the WSDL generation process and remove the required Datamembers from being injected into the generated WSDL.
Thanks

Hacking WSDL to not contain the information will not help you. Your service will still use full serialization of your types when passing them to your client and when deserializing them from your clients. Instead of hacking WSDL and WCF use DTOs for WCF service = new set of types which will contain only properties you really want to exchange with clients. Convert your master object to DTOs and vice-versa (you can either create your own custom convertors or use some framework like AutoMapper). This is the best practice.
I'm building a WCF SOAP application. The WSDL file has numerous operations of which many have the same argument type. The WSDL file defines all soapAction attributes as "''". When I try to start such a service WCF throw an exception saying that soapActions have to be unique.
After some googling I'm even more puzzled than before. I used SOAPUI to create a mock service with two operations which take the same input type and without the soapActions defined it always chooses the same operation. When the actions are defined it works fine.
My questions are:
Can you make a WCF SOAP service without unique soapActions (actually leaving the soapActions "''" as defined in the original WSDL)?
How can a service choose the right operation without the soapAction defined?
Edited:
I'm not in control of the WSDL. I'm using the WSCF.Blue tool to create a service stub from the WSDL file. I might be able to modify the WSDL, but I want to see if there is some possibility to leave it as it is.
It is not very clear from your question but I suggest you are building service based on some defined WSDL, aren't you? WCF by default uses SOAP action because it is required part of WS-I Basic Profile 1.1 offered by WCF services with BasicHttpBinding. WSDLs with empty SOAP actions are used when the action is defined by root body element.
WCF samples provides example of custom DispatchOperationSelector which is able to route messages to operations by their root body element. This is probably what you need to add to your service so that clients based on provided WSDL can call it.
I am attempting to replace a WSE service with the WCF equivalent where the WSDL is provided externally.
First, I used svcutil and wsdl to generate all the service and client classes (ATP, I'm only concerned with the service implementation.) I generated an empty WCF Service Library project and replaced/renamed the IService1.cs with a class named for the interface ServiceContractAttribute generated. I then renamed the implementation class Service1.cs with the name of the implementation-class JINDEXWcfListener.cs. I removed the generated code from this class and created class definition JINDEXWcfListener:[interface name].
The tool auto-generated the implementation of the interface. I used the single method adorned with [OperationContractAttribute] to put my local implementation code. I modified the default app.config generated to adjust the contract and service names as required.
When I start debug, I can see that the service is starting in the WTC. However, when the single operation is exposed, the is a red dot with a yellow question mark in front of the operation name. When I RC on the op name, I get "This operation is not supported in WCF Test client" with no additional information. What is wrong?
WCFTestClient has quite a few limitations. I have fought "problems" for several hours that later turned out to be just WCFTestClient problems. Complex objects can give you a lot of grief, also any custom lists, etc such as a custom implementation of the IList interface. Try out WcfStorm. I think they have a free version and a trial version.
As a contrast with a asmx file, how can I get in the visual service page that shows the available methods on the service?
http://soweb.adwiza.com/person.asmx
Versus
http://soweb7.adwiza.com/remote/person.svc
WCF does not have the list of operations page. The information is available by looking at the raw WSDL http://soweb7.adwiza.com/remote/person.svc?WSDL.
If you want a friendlier way to see that information as well as the ability to invoke the service (which the old ASMX page gave for simple types) then you can use the WCF Test Client (WcfTestClient.exe).
It will show you all of that information:
