Unfortunately, I am new to web services. I have a WSDL schema, which I have to provide as a service. So how can I do this?
Can someone please tell me instructions step by step?
I'm not sure why you would want to create a web service based on an existing WSDL schema (i'm assuming you mean WSDL and not WDSL).
You could use the WSDL.exe tool that ships with the SDK to reverse engineer the WSDL file to ASMX web services (older )
You can find more details here
However it is advised to use WCF for newer projects, you can then use svcutil.exe to reverse engineer your WSDL file instead.
find a description in a question answered How to use a WSDL file to create a WCF service (not make a call)
Hope this helps

Pretty new to WCF
I was browsing through various WCF Terminologies and seems stuck understanding this.
WSDL is used to describe the web service.
Currently, only SOAP based web services seems to have an associated WSDL while REST based services doesn't seem too.
Why?
Is it possible to generate WSDL for REST too?
Or are there any third party programs to do it ?
WADL is equivalent to WSDL for RESTful services
Since Microsoft .NET does not natively support WADL (WADL is WSDL for REST) providing a specific answer to your question is a bit difficult. That said, if you are interested in discovering more about RESTful services and WADL, you may want to consider experimenting with the open-source soapUI web service test utility (http://www.soapui.org/), which provides support for WADL.
The idea of codifying a RESTful API into a never-changing contract is antithetical to REST. Yes, WADL exists, but its purpose is to try and make REST more like SOAP, and with it destroy the primary benefit of REST: its evolvability.
If you feel like you want to use WADL, just use WSDL/SOAP instead.
You can use swagger.json as definitions for REST services.
you can check their github page for more information.

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
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...
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.
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.
