I've looked around for some tutorials, but everything I see is how to use REST services with my app. But that's not really what I need, I'm not doing basic GET requests, the end user needs to do some complicated calculations with several classes and variables from my web service.
In a Web Forms app, I would just add a Web Services solution and do everything in there. Is that the recommended solution for an MVC app?
We need to expose some services (i.e. AddressValidatorService, CustomerFinderService) that currently reside in an ASP.NET application to other applications within our organization. Exposing these services via WCF seems like a natural fit, but I don't see any best-practices for how to pull these common services into a WCF wrapper in such a way that my existing ASP.NET application can continue to use them with minimal code changes and/or awareness that the service they are consuming is no longer in-process. I'm especially looking for recommendations on how to structure the existing ASP.NET solution and whether to host our new WCF in the same solution or in some new shared WCF solution referenced by both our ASP.NET application and external callers.Also, is it bad practice to simply promote the DTOs currently only consumed in-process via ASP.NET to full fledged data contracts or is it preferable to create duplicate DTOs that are explicitly decorated with [DataContract]?

In Visual Studio 2005.I have created a Blank solutions(XYZ) and then add a ASP.Net Web Service Project(TESTP) under it.And then create a .asmx file(WEBFI.asmx) and then write a method and add [WEB Method] on top of the method.Now compile it.And then publish it.But in publishing folder I didn’t found any WSDL file which I should call in different machine (which is in LAN ).

I wonder if there are some differences between creating a WCF service and an MVC web-application. If you know of good links on how to create such a service for an MVC application that returns a JSON object please do post them.
View 1 RepliesI am trying to create an msi for a Web Service. I want the web service to be installed as a 'Web Site' not as an 'Application' under Default Web Site in IIS. I have code that creates a web site, but when I try to add it as a custom action under the install node of the msi, the code isn't getting executed. Reading about installers, it seems that anything under the install node gets fired after the installer has already started, if that makes sense. I want to be able to create the web site before the installer actually begins the installation process so that when the user comes to the window where he/she has to choose the Site under which to install the web service it can already be listed there and they'll be able to choose it.
View 1 RepliesI am trying to create a web service application that will need to use .net 4.0 for my datamodeling and other things. I noticed in VS2010 when I select New | Project the "ASP web service app" option is available if .net 3.5 is selected in the combo box but if I change that to .net 4.0 the option goes away.
After researching the only thing I found was a message where someone suggested to use the WCF web service option. I have never dealt with WCF before so I have no idea what path that will lead me down.
Here is my concern... we have existing web services developed in .net 3.5 that are already in use and we have windows based client applications that are developed in Delphi (version 7.0 to be specific) that already talk to these web services with no problems and no special coding required. Delphi can simply import the WSDL which generates an interface unit that gets compiled in and away we go. This new service app I need to create must also be accessed via the same Delphi apps.
The current asp web service apps generate 4 files when "published": web.config, .asmx file and in a in folder there is a .pdb and .dll file.
Can anyone tell me if support for this type of web service app is still available via .net 4.0 and if so how do I create the project or is that something that has been discontinued and thus no longer possible?
I have a large .NET based system running within the company intranet, which allows winforms users to see some live calculated numbers and a custom winforms control drawn live (but not real-time). The Forms users can also affect the operation of the system.
I would like to just show the live numbers on a website, along with the custom control. Nothing needs to come back from the web user, as the web app is meant to be just for monitoring. All the numbers can be calculated at the server. It's been a long time since I touched ASP.NET, and I need to know how to proceed. What are the steps in building and deploying such a website? Any caveats I need to look out for?

i have a requirement to build some sort of services that can easily be called to a 3dr party API.
the call can be done through simple

2) ASPX page
3) MOBILE device
should i create a separate web service project separately and create few methods [WebMethod] ?
also the method can be static?

I am creating new WCF service and i would like to do two way XML for communicating with third party vendors. My wcf service get the request from the outside program by means of URL and it should response accordingly.
Example - I have url which third party will call and put xml as a request, i have to get that xml, work accordingly and response back with either success or failure and appropriate xml. I need to make it completely automatic so anybody can call that url, it will validate that user and do the next step of request and response.
i am in the process of creating a restful service with WCF, the service is likely to be consumed by at least 500 people at any given time. What settings would i need to set in order to deal with this.

We are consuming third Web services.
Instead of using datatypes from web service proxy we need to create our own class which will take the values from web service output.
