converting a WSDL to a REST web service, Is there a C# version of this library?
http://wsdl2rest.sourceforge.net/
I was wondering if you really need a library for this? I mean as long as you have the WSDL you can create a service using the svcutil and decorate the methods with WebInvoke and WebGet also specifying the method (POST/GET/PUT) and the UrlTemplate. The methods would also have return types and input params based on your current wsdl.
I haven't tried it but I've been reading on the issue as my current project requires me to do so when I get that stage of our development effort...
Here are some sources:
How to use a WSDL file to create a WCF service (not make a call)
"Reverse" WCF Service (Building a server from a client definition)
How to use a WSDL File to create a WCF Proxy?
and so forth...

I am new to SOAP complex type web services. I attached down here the wsdl file.
My question is
how to consume the web service? I mean how to call and how to call the callback function.
if possible, use the below wsdl and give me an example with c#
wsdl here
[wsdl here][1]

The easiest way I know to consume a SOAP API is to create a C# project and add a service reference.
Then add the address of your website and Visual Studio will generate a proxy for your WebService.
You will be able to call it in your project (Website/ConsoleApp).
You can have a sample of how to call the client when you call the svc of your WebSite if you use WCF.
ex: http://<host>[/route]/<name of svc>.svc
We've requested a company to write a webservice that we can use to get some information.They have sent us WSDL and XSD files. Could you please tell me how I can use these files to query data?
I can do it easily if I have a link to a webservice. I just provide the link and Visual Studio generates web reference for me. After that I can use that reference just like a normal class. In this case I have no link. Just above mentioned files. Thank you.
You can create a proxy (add service reference in visual studio) from a wsdl file. You can read about svcutil at http://msdn.microsoft.com/en-us/library/aa347733.aspx, but VS2010 allow you to put a wsdl file on adress when adding service reference.
VS2010 can't create a web service reference from some WSDLs. Have
to write custom wrapper for those. OR edit your WSDL in a way so
VS can consume it. For example it may be ok for you to remove web
service method references for the methods that you are not planning to
use if those references create trouble for you.
Unless you're stuck with .NET 2.0, you should not use ASMX web service technology.
You should use "Add Service Reference" and point it to the WSDL on disk. It will create a set of "proxy" classes with methods that you can call just as though it were a "normal" class.
See "How to Consume a Web Service" for a walkthrough with example.
Use WSDL.EXE utility to generate a Web Service proxy from WSDL.
e.g.
wsdl /language:CS /n:"Microsoft.SqlServer.ReportingServices2010" http://<Server
Name>/reportserver/reportservice2010.asmx?wsdl

How to use a WSDL
If REST based web services are as simple as GETing and POSTing to a url and parsing the response wht exactly do we need a wsdl? Whats the point. I understand that when using SOAP based services it is used to construct the SOAP requests and responses but dont really see why visual studio provides me with a wsdl when I create a REST based service...
WSDL is designed to allow clients to discover service capabilities, primarily at design time. REST has the hypermedia constraint that requires that all service capabilities should be discoverable at runtime via the linked representations that they return.
Proper REST services are naturally discoverable therefore there is no need for a WSDL specification in addition.
There is no point in WSDL for REST services created with WCF because WCF supports only WSDL 1.1 (or 1.0) which cannot describe REST seevice. If you try to use WSDL generated for WCF REST service to create a client proxy you will not be able to call the service anyway. Visual studio templates for REST don't expose metadata so you will get useless WSDL only if you add serviceMetada behavior (and possibly also mex endpoint) yourselves.
WSDL 2.0 and WADL supports description of REST services and the point is similar as with SOAP services - describe what you can do with the service but in the REST way.
There's no point. WSDL is just a standardized description of what a service exposes and how can be invoked. You don't need WSDL, but you need some way of documenting what can be done with your service, so that clients know how to invoke it.
Disclaimer: My experience/knowledge of web services is very limited.
There is an existing web service WSDL that I have reverse engineered with wsdl.exe to create a C# proxy class.
Using Visual Studio 2008 I created a default web service template.
How do I reference the generated proxy class so that it will work in the web service?
For example -> calling http://localhost/webservice/service.asmx?WSDL will return the details from the proxy class.
First of all, you should not be using ASMX web services. Microsoft now considers them to be "legacy technology", and suggests that all new development of web service clients or services be done using WCF. Don't start off at a disadvantage.
Secondly, the normal way to make use of a WSDL is to use the "Add Web Reference" command in Visual Studio ("Add Service Reference" if you were using WCF). This generates the proxy classes for you and adds them to your project.
I'm not sure from your question that this is what you want, since you first talk about the WSDL, but then talk about a "default web service template". What do you mean to do with the "default web service template"?
Try using the svcutil.exe program (not WSDL.EXE) as follows:
svcutil YourWsdl.WSDL /language:C# /d:subdirectory
This should produce a number of files in the subdirectory. Take a look at the .cs files, one of which will contain an interface which is the service contract. That is the interface that your service must implement. Look at your "default" WCF service application and you'll see that it does the same thing - produces an interface that is implemented by the service.
Can any body have idea how to consume php soap web service that have no support wsdl.
I want to add reference in .Net to generate client but failed.
When i saw in browser with ?wsdl it shows message wsdl is not supported.
Simply said: you can not. WDSL is there for development environments to know how to deal with a web service. Whoever wrote the web serivce made sure (or was ignorant enough to now know) that it is not usable from any tooling support.
You might want to consult the PHP: SOAP Manual and verify that you wrote the PHP webservice correctly.
And you can also look at this example: PHP Webservice and C# / .NET SOAP Clients
You need to configure the SOAP Service to support WSDL
(Web Services Description Language) An
XML-based language for describing Web
services and how to access them.
Otherwise .NET won't know what or how to use it.
