WCF

Windows Communication Foundation (WCF) is a tool used to implement and deploy a service-oriented architecture (SOA) to support distributed computing where services have remote consumers. It features a runtime and a set of APIs in the .NET Framework for building connected, service-oriented applications. Services typically have a WSDL interface (Web Services Description Language) that any WCF client can use to consume the service, regardless of which platform the service is hosted on. WCF implements many advanced Web services (WS) standards such as WS-Addressing, WS-ReliableMessaging, WS-Security, RSS Syndication Services, WS-Discovery, routing and better support for REST services.

We have a requirement where we need to build a WCF service which can make outbound calls (as client) to backend services which requires 2-way SSL (mutual-authentication).

We have been trying this with no luck. It works with 1-way SSL (WCF as client), but when we set the backend services to require 2-way SSL, the handshake failed at the point where WCF is supposed to send its certificate to the backend service, but it doesn't.

Any one has experience doing this? Any clues of what the problem could be will be much appreciated.

Best Regards
Charles

This app.config is resided in my c# class library. and I have class library called service.cs


I also have web application in c# and try to called service.cs (of course I added reference inside of the web app)
and I have alert about "Could not find default endpoint element that references contract"

so I create another web application project and add web reference directly and the webconfig is exactly the same. there is no error and I can call as usual.
What did I do wrong?

Hi All,

I have compile error below.

using System.Web.Http;
 
using System.Web.OData;

Error      8      'System.Web.OData.Delta<ERVJGMERPDATASERVICE.TMCARCOLOR>' does not contain a definition for 'GetEntity' and no extension method 'GetEntity' accepting a first argument of type 'System.Web.OData.Delta<ERVJGMERPDATASERVICE.TMCARCOLOR>' could be found (are you missing a using directive or an assembly reference?)       

What component is missing ?

Hello Expert Team,

I am trying to develop a method in WCF service to dump data in an SQL tables
I asked the user to give us a json string with a specific format
if I test it for a small json , the method works correctly
but I tried to test for a long string it gives 'HTTP Error 414. The request URL is too long.'
 <WebGet> _
    Function GetHello(UserParam As String) As String
-----------------------
    Public Function GetHello(Json_Parameter As String) As String Implements IMobileservice.GetHello
        Dim ParameterInfoLength As String = ""

        Try
            ParameterInfoLength = Json_Parameter
        Catch ex As Exception
            ParameterInfoLength = ""
        End Try
        ParameterInfoLength = "This is the result of " & ParameterInfoLength
        Return ParameterInfoLength
    End Function

Do we have a solution?
Besides, I develop same method using a web services, it gives a window unresponsive to wait/kill, after a wait time ,  I get an answer, the method displays the string
 <WebMethod()> _
    Public Function GetHello(Json_Parameter As String) As String
        Dim ParameterInfoLength As String = ""

        Try
            ParameterInfoLength = Json_Parameter

            ParameterInfoLength = ""
        End Try
        ParameterInfoLength = "This is the result of " & ParameterInfoLength
        Return ParameterInfoLength

What do you suggest?

We have an MVC application that consumes a third party WCF service.
We are calling a method in that service that takes base64encoded byte array as one of the parameters among other parameters.
We also have to specify the Username and Password in the ClientCredentials before calling the method

Below are the web. config settings
<system.serviceModel>
            <bindings>
                  <wsHttpBinding>
                        <binding name="WSHttpBinding_ISampleOrderSubmit">
                              <security mode="TransportWithMessageCredential">
                                    <transport clientCredentialType="None" />
                                    <message clientCredentialType="UserName" />
                              </security>
                        </binding>
                  </wsHttpBinding>
            </bindings>
            <client>
                  <endpoint address="https://abc.test.sample.com/SampleOrderSubmit.svc/SampleOrderSubmit.svc" binding="wsHttpBinding" bindingConfiguration="WSHttpBinding_ISampleOrderSubmit" contract="SampleOrder.ISampleOrderSubmit" name="WSHttpBinding_ISampleOrderSubmit" />
            </client>
      </system.serviceModel>

Most of the time everything works fine.
But on certain occasions we get the following error:


System.ServiceModel.Security.MessageSecurityException: An unsecured or incorrectly secured fault was received from the other party. See the inner FaultException for the fault code and detail. ---> System.ServiceModel.FaultException: An error occurred when verifying security for the message.


This is the only error that gets captured at our end and since majority of the times it works fine, we …

I had my web service running nicely on a remote IIS server, but now it's broken. I believe I've got the relevant client and server servicemodel sections of the system properly configured. See attached files.ClientServiceModel.docxServerServiceModel.docxI have another website running just fine on the same server, w/ username/password authentication. I can run my service properly when the server is locally on my laptop. However now I can't access the remote service at all.  Can't do an "Add Service reference".  Elmah not working.

I believe that I don't have authentication properly set for the web service website
