wcf test client problem

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

I am attempting to run the WCF Test Client (from VS2010) on my Win2008R2 server.  I enter the correct service url for my http service endpoint and get the following error:

Failed to add a service. Service metadata may not be accessible. Make sure your service is running and exposing metadata.

Error: Cannot load reference assembly 'C:\Windows\Microsoft.Net\assembly\GAC_32\System.Data\v4.0_4.0.0.0__b77a5c561934e089\System.Data.dll'    Cannot load file C:\Windows\Microsoft.Net\assembly\GAC_32\System.Data\v4.0_4.0.0.0__b77a5c561934e089\System.Data.dll as an Assembly. Check the FusionLogs for more Information.    Could not load file or assembly 'file:///C:\Windows\Microsoft.Net\assembly\GAC_32\System.Data\v4.0_4.0.0.0__b77a5c561934e089\System.Data.dll' or one of its dependencies. This assembly is built by a runtime newer than the currently loaded runtime and cannot be loaded.

My service is hosted in IIS 7.5 WAS / .NET 4.0 (http binding).

Note , I had to manually copy the Wcf Test Client and svcutil from my workstation up to my Windows 2008 server.  Anyone else run into this error?

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.

Problem registering client side script to interact with AJAX controls

Im using some animationExtenders in my project. The thing is, the objects to be animated are created programmatically, hence i need to also build programmatically the javascript code that will interact with them.It runs properly but, when i interact with these animated controls and the javascript functions are supposed to get to work, i keep getting the usual run-time error saying that the javascript functions are not defined. But, if i check the final html code generated, i can see how all the controls i built programmatically are there ,as well as the script.Tried both RegisterStartupScript and RegisterClientScriptBlock, no luck.Any advice? thanks in advance

Problem with custom onBeginRequest-Handler on client-side when partial postback is triggered from ja

Hi, I have a Modal Dialog with a Ribbon, which starts a long running serverside operation. To inform the user about the progress, I implemented Dino Espositos "Progress Monitor Framework", which worked perfectly (after some work) - at least when I trigger the partial postback from a control inside the UpdatePanel used for displaying the progress. In this approach custom onBeginRequest and onEndRequest-Handlers are used to start and stop displaying the current status of the serverside operation. When I start the operation from a Button on the ribbon by doing "something" with the mentioned control via javascript the serverside operation is started, but my onBeginRequestHandler ist not called and the progress monitor is not "switched on" on the client. Here is what I´m doing in my javascript :  function pageLoad() { progressManager = new VCSharePoint.MultiEdit.Progress(); // Remove existing handlers Sys.WebForms.PageRequestManager.getInstance().remove_beginRequest(onBeginRequest); Sys.WebForms.PageRequestManager.getInstance().remove_endRequest(onEndRequest); // Register handlers for UpdatePanel client events Sys.WebForms.PageRequestManager.getInstance().add_beginRequest(onBeginRequest); Sys.WebForms.PageRequestManager.getInstance().add_endRequest(onEndRequest); } // onBeginRequest() // Called w

.NET Remoting Problem with Sponsor Renewal on CAO (Client Activated Object) Architecture

I have figured out a strange behaviour when using Client Activated Sponsorship and hope to get a hint from somebody who already got in touch with similar problems. The case is as follows: An Application is used by a server and a client. Both use (or try to use) the same objects after a user login. A lease of a session object on the server (serverSession) is initialised correctly with all of its regular remoting values in the lease for InitialLeaseTime (10) SponsorshipTimeout (5) RenewOnCallTime (10) In order to test the behaviour the values are set to seconds. It is easier to check the log every few seconds, than to wait some minutes until the Sponsorship Renewal call. If a client performs a login, the lease is according to its logged in state renewed each 10 seconds (or whatever the value is set to). So no problem so far. The lease will be alive as long as the client performs a logout, by the way it is used on a local network. Just compare the log (the renewal is firing every 10 seconds as expected): 2010-02-17 10:29:40.4338 Info Log5 SponsorObject:Renewal() 2010-02-17 10:29:50.4308 Info Log5 SponsorObject:Renewal() 2010-02-17 10:30:00.4328 Info Log5 SponsorObject:Renewal() 2010-02-17 10:30:10.4298 Info Log5 SponsorObject:Renewal() 2010-02-17 10:30:20.4318 Info Log5 SponsorObject:Renewal() 2010-02-17 10:30:30.4288 Info Log5 SponsorObject:Renewal() As soon as

Client Script Replace Problem with .NET 4.0 ScriptManager



I want to replace the WebUIValidation.js client script (located in System.Web assembly) with my own custom script using the new script replacement features in .NET 4.0.

The replacement works fine in a simple sample form I created, but in my much more complicated wizard form it fails.  On partial post-back the ScriptManager writes the System.Web version to the browser and I end up with both Microsoft's version and my version of the script in the browser. Since the System.Web version loads last, it replaces my custom script.

I am using the ToolkitScriptManager intead of the ScriptManager everywhere. The form that needs the replacement has dynamically created controls (including the validation controls) and has several control extenders based on the AjaxControlToolkit.

Does anyone have any ideas on what could be going wrong, or have any ideas on a workaround for this?

Any help will be appreaciated,


Problem with getting client's IP address in WCF service on IIS7



I have deployed a WCF duplex service on IIS7 that gets the client's IP address and based on that if the IP address repeats, the client is not given access to service. The problem is that when I deploy it on IIS7 and try to access it from another PC on LAN, it identifies the new PC having the same IP address as the one that the service is deployed in(just for testing purpose, I am returning the retrieved IP address to client), and So, I am not able to access the service from another PC. 

Can anyone help me with this?



SSRS Print problem on client machines



Initially after deploying SSRS 2005 report on server, the client machine could not avail print functionality because of the error "Unable to load client print control". Inspite of allowing ActiveX installation, the print functionality was not working.

Googling on this issue I found that rsclientprint.dll needs to be registered in C:\Windows\system32.

After successfully registering this dll, print functionality started working on some machines. However on some machines it started giving the error 'Error loading resource library.(0x8007007E)'.

Now I am stuck as to what needs to be done. Any help is appreciated.

Problem setting endpoint address URL dynamically at runtime in client


I have a WCF web service and clients running on separate windows server 2003 machines. I'm using windows integrated authentication to authenticate the clients. All of the clients and the service are running in appPools in IIS6 as specified active directory users. I have added the service as a service reference to the client project in Visual Studio 2008. This works fine in the development network. To run it in the Production environment I need to change the URL and the UPN at runtime to the production values, but whatever I try it just throws errors? In fact the only thing that worked - but isn't really practical - is when I removed the development service reference and added the production service reference to the project using Visual Studio before deployment. Surely there is some way to change the endpoint at runtime??? I must be missing something simple. Please help! :)

Here is the relevant part of the client endpoint:

         < endpoint address ="http://dev.happyfunland.com.au/FunService.svc" binding ="wsHttpBinding"
