Add Service reference not updaing the client apps web.config file in .Net Framework 4.0

Posted By:      Posted Date: September 29, 2010    Points: 0   Category :WCF

Hi Team

I am doing some experiments with WCF on .Net 4.0. I have created a service in 4.0 and add a new empty web application to consume my Service. When i added a service reference from the IDE, i can see the web.config file is not updated with the Servcie end points. How do i solve this issue?

My web.config in the client looks like this after adding the service reference.

Not able to read Config File data in Windows Service

Thanks in advance.

WCF session client service reference "State" is not updated when the server side has closed


I am using vb.net (Visual Studio 2008 with framework 3.5). I have a server that exposes several services requiring sessions. I am using wsHttpBinding for all. One of my requirements is to allow non-dot net third parties to access these services. When a client connects to a service and then some time later the server goes away, the state of the connection is still reporting "open".

Currently I have implemented a "ping" function on the server. My client calls this function every 5 to 10 seconds and if the server does shutdown, I get alerted with an exception error. This works, but I was wondering if there is a way where I don't have to call my ping function?

I don't want to use a dual connection binding and I was hoping to use the connection state variable? But, I don't know how to get it to update by itself. The client user application could just wait until it goes to invoke a service method, but I was wondering if there was another way.

Thanks in advance!!


Can a table name impact generating the service client when creating Service Reference?


I have a new WCF service I'm writing under VS2010 and IIS 7.5.  The service includes a table named Client.

When I built my test class and added the service reference, the first test was confirming the creation of the client.

My service reference did not generate any client that I could call .Open on!!!! I was wondering if it is due to that table name???

 Edited to add that I tested the service through the browser and it brings up the page and XAML fine.

Thanks for any assistance!

Connection times out when WCF client tries to call WCF service, both in Windows Forms apps



The exception message is: Could not connect to TCP error code 10060: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond

What I am trying to do: a WCF service is self hosted in a Windows Forms application. The WCF client is in another Windows Forms application. Eventually, the client is supposed to run on a computer somewhere out there on the Internet and send messages to the server which is running on my home computer. This is my first attempt at making a remote WCF call.

I have success when server and client either run on the same computer, or are running on different computers attached to my little in-home LAN. When I try to route the client's request via Internet (in preparation for having the client reside out there somewhere) I get the exception reproduced in the first paragraph above after waiting for about 20 seconds.

OS is WinXP Pro with SP3. Using Visual Studio 2008, Visual Basic. is the IP currently assigned to me by Comcast (I watch carefully to see when it changes; also, I altered it for purposes of asking this question).


Setting of sharepoint 2010 custom WCF service "web.config" file for both HTTP and HTTPS



        I have created a custom SharePoint 2010 WCF service that is deployed to 14\ISAPI\MYService folder. The issue i am facing is that this service should be accessible from all Web applications, that can be HTTPS (i.e. SSL) enabled or normal HTTP. If i am making in web.config file for web application that has HTTPS enabled, then it fails for Web applications having normal HTTP configuration. My requirement is that when this WCF service is deployed it should accessible from all web applications that can be HTTPS or HTTP both. I went through number of blogs and tried whatever option they had suggested but none of them worked for me :(. Here are some of the blog that i tried:-

Practical Multithreading for Client Apps

Writing applications that use multiple threads is often considered an advanced programming task, prone to errors. In this month's column, I'll focus on a practical application of multithreading in Windows® Forms applications with some real benefits, while attempting to keep things simple. My goal is to present multithreading in an approachable way that addresses a very common need: writing applications with a user interface that remain responsive to the user.

Any framework for creating a job scheduler service?


Just curious to know if there was any official Microsoft code blocks, classes, or such for writing a service that runs other assemblies or WCF services?  That can be configured easily from a web page, pre-coded, for running tasks at certain times on certain recurring intervals?  I've already built one but am open to anything done better- which I'm sure there is.  Thanks!!!

Problem to obtain client IP on web service



I'm having problems to obtain the client IP on web service. Here's my scenario:

One server with Windows 2003, hosting the web service using .Net Framework 2.0, with IP and host name ServerTransaction.
Other server with Windows 2003, hosting a web application using .Net Framework 2.0, that consuming the web service on  ServerTransaction, with IP and host name ServerApplication.
Many other computers on the local network (IPs:,,, ...) acessing the web application on ServerApplication.

On the code of the web service I've tried to use HttpContext.Current.Request.UserHostAddress or HttpContext.Current.Request.ServerVariables("REMOTE_ADDR") or HttpContext.Current.Request.ServerVariables("HTTP_X_FORWARDED_FORR"), but always I can only get the IP of ServerApplication (

Any idea or tip?

Thanks and sorry for my bad english.
