I have downloaded a WSDL file from Internet and just want to know how to use the webservices out of the provided wsdl file using ASP.net version 2.0.
You can just add a web service reference. Back in Visual Studio 2005, this was in the context menu of the project and is called "Add Web Reference". In the dialog, just enter the location where you downloaded the WSDL file and a proxy will be generated for you.
When you use Add Service reference
The “Address” text box at the top can be used to type the URL to the Service Description, or “WSDL” file. Since the service is in the same solution as the project we’re trying to add it to, we can take advantage of the “Discover” dropdown at the right. Clicking the arrow shows “Services in this solution”:

I think this is answered in this post: You can use WSDL.exe to generate a client, which you can access from code.

I am working on asp.net core i want to consume soap web service in my project in previous i can consume soap web service using asp.net mvc, but how to consume it in ASP.NET core,if you have an idea or an example.
Regards,
Assuming you are using Visual Studio, you can right-click your project in "Solution Explorer" and choose Add -> Connected Service.
In the new window that appears you choose Microsoft WCF Web Service Reference Provider.
This will open a popup where you can type an URL to the WSDL definitition of the SOAP web service. Click "Go" to fetch the WSDL from the URL, or click "Browse" to use a local WSDL file.
You should now see the SOAP service in the "Services" area. Give your service a proper namespace and click "Finish" (there are other options, but you can leave them on their default settings).
Visual Studio will now generate some files and classes. One of these classes is named ...Client. Make a new instance of this class and you should find that it contains all the methods the SOAP service provides. Call these methods (with the appropriate parameters) and you will invoke the service.

I'm trying to add a web reference to a restful service, here is one sample URL:
http://dailymed.nlm.nih.gov/dailymed/services/v1/ndc/0409-3613-01/spls.xml
and I'm getting the following error (I'm guessing because I have no access to WSDL or DISCO they aren't listed on the API help page):
The document at the url http://dailymed.nlm.nih.gov/dailymed/services/v1/ndc/0409-3613-01/spls.xml was not recognized as a known document type.
The error message from each known type may help you fix the problem:

I don't have access to this web service, it's run by the national library of medicine. Any thoughts on how I can add a reference within VS? Do I have to access this manually?
There is no standard metadata format to describe REST services. There's nothing similar to WSDL. Therefore, "Add Service Reference" or "Add Web Reference" won't work.
You'll have to look at the documentation of the service, or possibly at sample code, and build your own access layer.
I have an WSDL at my disposal. it's address is : http://gy30.com/webservice/index/wsdl
when i import the WSDL through asp.net "add service references" i can see the "Operations(methods)".
After importing the WSDL i can't see any methods in the object browser. And there isn't any generated classes for this kind of WSDL.
I have read several posts on S/O and many articles about how to consume WSDL by googling, but i didn't find any solution.

what are the problems ?
If i am not mistaken "Add Service Reference" is for wcf services. What you need is add Web Reference.
This service is legacy and you should use "Add Service Reference" -> "Advanced" > "Add Web Reference" and you will see old beautiful Add Web Reference dialog. And it will add reference but i couldn't consume this service. There was something wrong.
I've written an ASP.NET website along with a companion WinForms desktop application, which is used to maintain the site.
The desktop application needs to create a user. However, this is awkward because I would need to ensure all the membership settings are exactly the same as they are in my website's web.config file.
It would be easier if my desktop application could "call into" the website somehow and tell it to create a user. It seems like a web service would be a good option for this. However, Visual Studio doesn't have an option to add an ASMX file. And if I create a separate, web service application, then that application would have the same problem my desktop application has.
Is there a way to add a single web service to an existing ASP.NET application? Any links? Thanks.
Visual Studio doesn't have an option to add an ASMX file
In the Web application project, or the WinForms project? I assume you mean that you cannot add a Web Reference from within your WinForms project; adding an .asmx file to the WinForms project is not necessary. The Web application project should have the .asmx file, which is called by the WinForms project using a web reference.
In the WinForms project you can consume a web service by right-clicking References in the Solution Explorer, then choosing Add Service Reference... (in Visual Studio 2008; other versions may say Add Web Reference...). Then just enter the web address (which may be local in your case, e.g. localhost/foo.asmx) of the web service (.asmx).
See the section "To call an XML Web service synchronously" in this MSDN article: Calling XML Web Services from Windows Forms.
As an alternative, this MS KB article shows how to use the WSDL tool to generate a class that can consume a *.asmx URL. (The article uses VB, but you can switch the parameter to CS to generate C#.)
Update
To add an .asmx file to your Web project, right-click the project in Visual Studio, select Add -> New Item... -> Web Service. If there is not a "Web Service" item any where in the template browser dialog that comes up, then you are missing the template or you're looking in the wrong place.
I'm trying to consume a WSE enabled Web Service from an ASP.NET Web Site.
I've installed WSE 3.0, used the config tool to add WSE info to my web.config and then done an Add Web Reference.
I believe that the problem may be that this is a Web SITE, not a Web APPLICATION. As such, the proxy class is generated at runtime, perhaps not adding the WSE magic.
I can access the proxy class from metadata, and it's of type System.Web.Services.Protocols.SoapHttpClientProtocol, which as far as I can tell doesn't have any WSE functionality.
I realize that this is all old technology, but I don't get to decide what the servers run :(
Any help would be greatly appreciated
You are wrong, proxy is generated when you are adding web reference.
Could you tell me how you are adding web reference to the website.
Please refer following article - http://msdn.microsoft.com/en-us/library/5sds7a0b.aspx
After you have located a Web service
for your application to access by
using the Add Web Reference dialog
box, clicking the Add Reference
button will instruct Visual Studio to
download the service description to
the local machine and then generate a
proxy class for the chosen Web
service. The proxy class will
contain methods for calling each
exposed Web service method both
synchronously and asynchronously. This
class is contained in the local .wsdl
file's code-behind file. For more
information, see Web References in
Visual Studio and Add Web Reference
Dialog Box.
