Basically, I have a server-side type "Foo" with members X and Y. Whenever I use Visual Studio's "Add Server Reference" then I see the WSDL and the generated proxy both append the word "Field" to all the members and change the casing of the first letter. IE, "X" and "Y" are renamed "xField" and "yField". Any idea why this is happening? I ...
Duplicate: although this is a good discussion, this is a duplicate of Web Services — WCF vs. Standard. Please consider adding any new information to the earlier question and closing this one. Could anyone recommend me some documents to describe why WCF is better than legacy ASP.Net web services? I am especially interested in performan...
I am consuming a web service internal to my company from ASP.NET. I've used svcutil.exe to connect to the service and generate the bindings and classes from the wsdl. I am able to connect to the dev version, which does not require authentication. Now we are adding in security. My new URI uses https but also requires user credentials. I...

It's is written in VS2008 / C# / .NET 3.5 and my dev box is Vista SP2 with IIS 7. At the moment the service is nothing more than the default structure since I am literally after testing a connection to i...

Hi. I'd like some basic guidance on setting up my WCF configuration. This is my first serious effort with WCF (and first post on stackoverflow). I have a WCF class library (APILibrary) that I am referncing in my web project. In the wcf library, I currently have two services - IAuthService and ITradeService. Along these lines, I h...
Hello, I have a client/server project, communicating with WCF (Named Pipes for now, but that can change - but I cannot use IIS). This project is integrated with Active Directory. This program is designed to give users permissions that normally don't have permissions, by acting as a sort of proxy. The user uses the client to "request"...

I have a Silverlight app that is using WCF to connect to some services. The services are running as a windows service and are on a different port, so I have to use a client access policy file. In the WCF services there is a method for getting the client access policy. [WebGet( ResponseFormat = WebMessageFormat.Xml )] public Stream GetC...

I'm just starting out with WCF web services, and I'm having a really hard time finding a very simple tutorial, so I thought I'd ask some questions here. Here's my setup: I have a WPF desktop application that needs to send data over the internet to a web service on our server. The way I see it, I have at least these four options: I ca...

I'll take TransactionScope as my example for now. Imagine every method in your WCF carries out database activity, and you want every call to be in a transaction. You could include a using block in every one of your methods, and that would work fine. I'm wondering if there is an easier way to do this at a service, rather than method-leve...
