I've created a simple WCF service hosted by ASP.NET web site:
[Code]....
I can add references to this service as to WCF service, as to WebService.WcfTestClient application successfully recognized service and its methods.
But "Web Service Studio" [URL] can't get a list of operations... Why? How to diagnose/resolve that?
P.S. I work under VS 2008 using .NET 3.5
Is there a way I can see the list of operations that are exposed by a WCF service same as we can with a asmx service?
View 1 RepliesI have one asp.net application, in which i am using "Calling WCF Service Operations in AJAX" method. I finished my work without the service hosting in IIS. I got the correct solution. But now, i have another requirement in which i am using the WCF service which is hosted on local host iis. But in clicking the button i got one javascript error like object expected. I don't know why this happened?
My code is shown below.
<fieldset style="width: 804px" align="center">
<legend>Consuming WCF Service using Client-Side AJAX</legend>

I have built a WCF Service that is being consumed by a Silverlight app. At first I created one method that was very simple:
public String SfTest()
{
return "SF Test";
}
No poblem. My silverlight app references my service and displays "SF Test" in a textbox. Now I add a method to my wcf service like this:
public List<String> GetTest()
{
List<String> list = new List<string>();
String a = "a";
list.Add(a);
String b = "b";
list.Add(b);
return list;
}
I update the reference to the service in my Silverlight app and the using statement in my xaml cs page throws an error like the service doesn't even exist although it is there. I am assuming the problem has to do with datatypes or serialization or something like that but it is driving me up the wall. Why can't I consume a simple generic list in my Silverlight app through the WCF service.
i want to create a web service which consists of CRUD operations Create, Retrieve, Update and Delete. creating web methods on insert and update operations.
View 2 RepliesI have developed a WCF .NET web service. It has evolved from a console application, hence some shortcuts were taken in VS 2008 rather than establishing the project from scratch as a WCF Web Service.
View 4 RepliesI have a simple ASP .NET web service running and I want call it from a php client. I m using nusoap soap client.
The following is the client side php code:
<?php
require_once('lib/nusoap.php');
$wsdl="http://localhost:64226/Service1.asmx?wsdl";
$client=new soapclient($wsdl, 'wsdl');
$param=array('number1'=>'2', 'number2'=>'3');
echo $client->call('add',$param);
?>
The web methods I have created in web service are as follows:
namespace WebService3
{
/// <summary>
/// Summary description for Service1
/// </summary>
[WebService(Namespace = "http://tempuri.org/")]
[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
[ToolboxItem(false)]
public class Service1 : System.Web.Services.WebService
{.........
However when I run the above php code it does not return the added value of the passed parameters. Instead it previews the word 'Arrays' I m not experienced in php programming. Am I doing something wrong the above codes?

How do I write the code?
I have a WCF service hosted on an external server (other domain) and I'm trying to consume it from a command line application. I receive the following error:
The request for security token could not be satisfied because authentication failed.
The service is configured inside a web.config file:
<system.serviceModel>
<bindings>
<wsHttpBinding>
<binding name="wsHttpBinding_IRun">
[Code]....
On the client side, I create a custom binding to connect to the service. Here is the security configuration:
standardBinding.Security.Mode = SecurityMode.None;
standardBinding.Security.Transport.ClientCredentialType = HttpClientCredentialType.None;
standardBinding.Security.Transport.ProxyCredentialType = HttpProxyCredentialType.None;
standardBinding.Security.Transport.Realm = "";
standardBinding.Security.Message.ClientCredentialType = MessageCredentialType.None;
standardBinding.Security.Message.NegotiateServiceCredential = false;
standardBinding.Security.Message.EstablishSecurityContext = false;
standardBinding.Security.Message.AlgorithmSuite = SecurityAlgorithmSuite.Default;
I'm not using any security mechanism for authentification but still, the service seems to be expecting one. When working on different domains, is it mandatory to use a basic authentification?
EDIT: I wasn't referencing any binding configuration at my endpoint. Once the reference was set, I received another message error:
{"The message with Action 'http://schemas.xmlsoap.org/ws/2005/02/trust/RST/Issue' cannot be processed at the receiver, due to a ContractFilter mismatch at the EndpointDispatcher. This may be because of either a contract mismatch (mismatched Actions between sender and receiver) or a binding/security mismatch between the sender and the receiver. Check that sender and receiver have the same contract and the same binding (including security requirements, e.g. Message, Transport, None)."}
The issue was caused by my client's binding. While I was creating my custom binding using the standard 'WSHttpBinding', the 'SecurityMode' property was set to 'Message' instead of 'None'. Now the code looks like the following and the service finally works:
WSHttpBinding standardBinding = new WSHttpBinding(SecurityMode.None, false);
CustomBinding myCustomBinding = new CustomBinding(standardBinding);
I have a simple WCF service that I call server side from code behind via a service reference. It's used for validation and works and was automatically setup by Visual Studio and is using SOAP I think because the binding is wsHttpBinding.
I want to use the same WCF service, but call it client side from jQuery using ajax(). I'm trying to implement it by way of these instructions.
But if I make the changes to get the client side call working, I have to add the decoration below which I think will break what works on the server side and also change the system.serviceModel section in web.config.
[WebInvoke(Method = "POST",
BodyStyle = WebMessageBodyStyle.Wrapped,
ResponseFormat = WebMessageFormat.Json,
RequestFormat= WebMessageFormat.Json) ]
How do I have a WCF service that can be called both from the server-side and client side (jQuery/ajax)?
Or put another way, this may be incorrectly worded, can an endpoint have multiple bindings?
I need to send a X.509 client certificate to a web service in byte array (not attached to request). Besides the certificate, the caller will also send data and signed data. From the web service I can verify if the signature is ok but I don't know what is required to verify that the certificate is ok. I have the client certificate issuer CA trusted in Server (where the web service runs).
More specifically, how can I verify if a X.509 certificate itself is valid? I need to do it in web service not from IIS.
I'm trying to receive a Client Certificate in a Web Service and having some problems.
Client
[Code]....
The certificate seems to be correclty loading and added to the client.
The client connects to the server with HTTPS.
Server:
[Code]....
cert.IsPresent is false and all certificate fields are empty.
IIS is configured to Accept Client Certificates.
Reproduced in two environments:
- Windows 7 x64, IIS 7, VS 2008, .NET 3.5
- XP x86, IIS 5, VS 2008, .NET 3.5
Always in the Web Service the Client Certificate is not proesent. I haven't been able to find any other configuration I should do.
can i install WCF (windows service) on client machine and call this service on asp.net web page(on the server machine)?
View 4 RepliesI have a few web servers behind an Amazon EC2 load balancer. I'm using TCP balancing on port 80 (rather than HTTP balancing). I have a client polling a Web Service (running on all web servers) for new items every few seconds. However, the client seems to stay connected to one server and polls that same server each time. I've tried using ServicePointManager to disable KeepAlive, but that didn't change anything. The outgoing connection still had its "connection: keep-alive" HTTP header, and the server kept the TCP connection open. I've also tried adding an override of GetWebRequest to the proxy class created by VS, which inherits from SoapHttpClientProtocol, but I still see the keep-alive header.
If I kill the client's process and restart, it'll connect to a new server via the load balancer, but it'll continue polling that new server forever. Is there a way to force it to connect to a random server each time? I want the load from the one client to be spread across all of the web servers. The client is written in C# (as is the server) and uses a Web Reference (not a Service Reference), which points to the load balancer.
I am having a strange issue in my C# Console Application:
Name Space: WcfConsoleApp
Main Class: Program.cs
Name Space: WcfConsoleApp.ServiceReference
this namespace contains the WCF service reference
After building the project, the Program.exe avaliable in Debug folder is executing fine as expected.But when i move the exe to Client, where i need to actually run this exe, it works fine up to the line where i am referencing the Service, the line is:
WcfConsoleApp.ServiceReference.ServiceClient service = new WcfConsoleApp.ServiceReference.ServiceClient();
the consoel app crashes on the client machine at this line. (i know this because before this line, i display some mesage on the console)the same .exe and works fine at my development machine.I am sure it has to do some thing with reference path, i think the program is not getting to the path where service reference is avaliable. I have copied the full project folder as it is to the client, but still its is not working.
I have consumed an external webservice in my client application using WCF. And every thing works great in my Dev box(XP with IIS5.1)But when the same application is moved to Prod server(Win Server 2003 with IIS6.0) it fails. Below is the exception caught:
There was no endpoint listening at http://MyExternalWebServiceUrlWithSessionId could accept the message. This is often caused by an incorrect address or SOAP action. See InnerException, if present, for more details.And the InnerException is: Unable to connect to the remote server.My Config file has the below settings:

I developed a web service in VS2010 on my local machine, wrote a consumer of it also locally, and that all works.
I copied the dll and the asmx file to our server, and I am getting an error when I try to invoke it from a browser (also still on the server machine) to make sure it correctly exposes its web methods, but it is not, it is saying "Could not create type 'Service'". That error comes from this line:
Line 1: <%@ WebService Language="C#" CodeBehind="~/App_Code/WarrantyDuplicate.cs" Class="Service" %>
There other web services in the same folder on the server that all work fine so I don't believe it's an IIS setup thing.
This is my first web service in C# and when I created it in VS I did think it odd that the code behind file went into App_Code (as you can see from the line in the asmx file) and is just named dot-cs rather than asmx-dot-cs. But since it worked fine locally, I wasn't sure that mattered.
I have asp.net 2.0 site which is calling web services hosted on another server. When i have an xml file from where web service ip for eg. www.mysite/webservice1/myservice.asmx is given. When i call the same server from developer machine using local networkit works fine.But the same is when hosted remotely and from client end when services is called reading xml fiile from client machine it given a message 'remote server not connecting'.
View 1 RepliesI am not sure which approach I should use. I have a web application that needs to get/receive data from a third party application that is in a secure remote network. The data needs to be secure during transport. The data layers cannot be exposed and the databases will not talk to each other. The data will be received from remote application on demand, or will get at scheduled intervals.
I have looked at WCF, but not sure if this will work. Can a WCF service be used to receive data as needed from a remote sender or service? Is this a secure way of doing it? I have also looked at SFTP using some XML/XSLT, but I don't think this is the right way to go. In addition, some data may be transported from my web application to the remote application (mostly reports at first). What protocols are used to transfer data between HIPAA compliant applications?
I am writing two ASP.NET apps. One is a web service that provides xml data and the other is a web client that will use the service to display and manipulate data. I would like for the web service to do the membership authentication and authorization. Is there any way to simply point the login controls in my client application to the web service instead of to a database. I assume I would have to provide the necesarry methods in my web service interface, which would then use the membership provider database I created and pass the results back through to the client.
Is this possible? I have seen many articles on security provisioin from a web service but none has really been what I am looking for. I was hoping that, since my service and my client are both written in ASP.NET, there might be some built functionality that would benefit me.
I'm currently trying to work out the best way to build this web application, which will then be intergrated on other systems, such as WinForms, Intranets etc.
We hope to include the usual layers i.e. DAL, BLL, BOL and UI but I have been experimenting with Entity Framework 4 and WCF Data Services and managed to get something in place where I was using WCF as a gateway to EF4.
i.e. Adding a Service Reference to my project and then using the EF4 context and writing LINQ queries against the DB
e.g.[Code]....
Now with the current setup I would still need to write a DAL Class Library, that interacts with the Data Service, because as I said WCF Data Services only seems to be a gateway, I can't see where to put the code (above) in the Data Service and then how I could these methods.
My questions are: 1. How do I develop a WCF Data Service in such a way to allow this behaviour - I know how I could do it using ASMX web service, something like [Code]....
2. If I am to use WCF Data Services, how is serialization handled (if at all) - again I know how to do something in ASMX web services
3. Again, If I am to use WCF, how do I add Security and only allow my applications to access the web service - for obvious reasons
4. Would it be possible / logical to also include the Business Logic Layer into the web service?
Every month I have to email out links to demo music tracks that I make. I have like 30 labels and it takes me ages to write out an email to each one. I dont want to purchase my own domain name yet so is there a free email provider that I can sign up to that will allow me to use .net library to automatically send out messages?
