can WCF be used to create consumer of the older web service technology?

Posted By:      Posted Date: October 04, 2010    Points: 0   Category :WCF

I know wcf is what to use for new web services development. I have not done any web services dev at all yet, using the previous technology or wcf. Right now I'm just starting to learn about web services dev... I fully intend to use wcf for anything I do, but I was wondering if I should still learn the previous technology specifically for the case of consuming the service, for consuming existing services created using the previous technology? Can I just use wcf to create client side consumer of a web service that was created using previous technology, or would I have to use the older matching client side of the equation? 

for example, I was just reading this:

do I need to bother with the older?

Seeing the SOAP request sent from a Web Service Client/Consumer

Hello, I am building a web service consumer in C# in VS2010.  Using the provided WSDL, I need to build appropriate headers and use certificates, SSL (user name & pass), & WS security.  I am getting an error from the webservice side, specifically processing the <wsse:Security> header. Is it possible for me to see the exact request I am sending to the Webservice? I'd like to see the values of the pieces of the header that get put in and such. Is it possible to have human readable serialization of what's being passed in right before the error? Thank You

Create a new process in web service using delegated impersonation context

Hi, I've written an ASP.NET 2.0 web service which is consumed by a web application which goes out and gets configuration data back from newly built win2k3 servers in a large enterprise. I am using kerberos delegation and impersonation to pass through the users domain admin rights to interrogate the server which has just been built. The web pool identity (IIS 6.0) runs under a low priviledge service account. I have all the delegation part working ok. The problem I am having is that I want to programmatically kick off a process which executes a cmd line executable and redirects the output, all under the context of the user who's being impersonated. I understand that the process will be external to the impersonated thread, so will end up running under the worker process identity, which is why I'm getting an "access is denied" message. I've been reading about the CreateProcessAsUser and createprocesswithlogonw API functions but all I've seen is examples where people specifically state the username and password in their code. This is not something I can do as the environment is very secure, so what I need to do is seamlessly get the identity of the impersonated user, and some how feed that into a function which will create the process under the correct domain admins identity and feed back out the StdOuput. Is this something that can be achieved, and if so, how? Man

how to create a doc library item using web service

Hi, I think this is a common question, but I coulnd't come up with anything at this point. I'd like to create an item in a document library using SP web service. - no uploading a file. I have created an item using ../copy.asmx web service. Using the WS function(copyWebService.CopyIntoItems function), it seems suitable to create an item AND at the same time to upload a file. I don't think I can just create an item with this function. How do i just create an item? any reply is appreciated.  

Web Service ParserError Could not create type

Getting error message with our web service: Description: An error occurred during the parsing of a resource required to service this request. Please review the following specific parse error details and modify your source file appropriately. Parser Error Message: Could not create type 'ATGIntegration.B2CBlueprintOMSIntegrationWSBinding'. Source Error: Line 1: <%@ WebService Language="vb" CodeBehind="Service.asmx.vb" Class="ATGIntegration.B2CBlueprintOMSIntegrationWSBinding" %>   Two versions of this web service installed on a server (one for development) with the only difference being the web.config file. Web service worked without error for over a year. Recently made some changes to the code, compiled and copy and pasted bin files to the bin folder for the development web service. Then this error appeared. Then I put back the original bin files but same error. At this time the live web service was still working. Later I copied bin folder from live to dev and that broke live. I can fix this error by rebooting the machine, accessing the web service in error, making any change to the web.config file and finally accessing the web service again. The problem is that this error re-appears after a random period of time for no obvious reason. I follow the process again to fix. I have done this process 8 times now. Both dev

Create Multiple datafields in a Web Service

I have been working on this for awhile.  What I am trying to do is to retrieve the telephonenumber, mail and physicalDeliveryOfficeName from active directory  I have debugged it and it seems to work but when I connect to the data source in Infopath, there is no value.  Also, the data source has a group field called "choice."  I have no idea what that is.  I am using a contact select to fill out and the value of the AccountId will populate another field.  I use this field to choose the LoginName on the query and then run the query on the data source.  This should pupulate the email, phone, and location fields on the main data source.  Here is a sample of my code: Imports System.Web.Services Imports System.Web.Services.Protocols Imports System.ComponentModel Imports System.Net Imports Microsoft.sharepoint Imports Microsoft.SharePoint.WebControls Imports System.DirectoryServices Imports System.Data ' To allow this Web Service to be called from script, using ASP.NET AJAX, uncomment the following line. ' <System.Web.Script.Services.ScriptService()> _ <System.Web.Services.WebService(Namespace:="http://microsoft.com/webservices/")> _ <System.Web.Services.WebServiceBinding(ConformsTo:=WsiProfiles.BasicProfile1_1)> _ <ToolboxItem(False)> _ Public Class GetADProperty     Inherits System

Cannot create unknown type when loading WF Service from loose Xaml with ActivityXamlServices


I am trying to host a WF4 (RC) Service dynamically. I have a test solution with two projects. The first is a declarative workflow service library with one root Flowchart activity in it, and a simple custom code activity. The workflow service library does not depend on any other custom assemblies or references. The second is my host app, which in my test solution is just a console application.

In my host app, I am attempting to the use ActivityXamlServices to load the Xaml for the workflow service into an activity, and then use the WorkflowServiceHost to fire up a workflow instance using that activity.

As soon as I try to new up the WorkflowServiceHost object, I get this exception...

Cannot create unknown type '{clr-namespace:DeclarativeServiceLibrary1}CodeActivity1'.

If I remove CodeActivity1 from my Flowchart designer, everything runs fine. If I add a direct reference to the workflow service project from my host project and then create a WorkflowServiceHost using an instance of my Flowchart activity instead of the activity created from the Xaml, it also works fine.

It seems to not like using my CodeActivity for some reason when loaded dynamically.

Need to create a service to allow client application to update their data



I want to create a  WCF Service to transfer data to our clients application(WPF).

using (var myConnection = new SqlConnection(ConfigurationManager.ConnectionStrings["ConnectionString"].ConnectionString))
const string query = "select a.ID,a.Code,a.Description,a.unit,a.rate,a.rate3 from tariff.dbo.tariffdata a, tariff.dbo.code_history b where a.id = b.id and b.endofvalidity is null";

create web service with http-post method


hi All,

we need to expose a web service to the 3rd party vendor which can only call using POST protocol, NOT SOAP.

So my question, is it better to build a web service or just simply .aspx page?

Also is there any best practice documentation on this.

How to create 2nd instance after applying service packs?

I've read that to create a second (named) instance I simply need to rerun the setup.exe program. But that setup.exe has no service packs applied to it. After installing the 2nd instance, will I need to apply the service pack to it? Will there be any impact on another instance already running that already has the SP applied?

Create an exchange interface to call a Windows Service with WCF


I'm develpong an application that consists on a Client that communicates with a Windows Service via WCF.
I have three projects defined: MyClient, MyService, MyExchangeClasses

The first two are easy to understand, client and server. The MyExchangeClasses project contains the interface for MyService remote function calls and contains the implementation of those classes that are passed via parameter o are returned by the remote functions that implement the interface I've already mentioned.

For example I have one remote funciton defined in the interface like this:

public interface IService1
   IEnumerable<MyObject> GetAllMyObjects();

And MyObject is defined like this:

public class MyObject    
    public String Name { get; set; }

So in order to make it work MyExchangeClasses needs to be referenced in both MyClient and MyService classes.
