Hi,

I am a learner on silverlight. I am creating a silverlight application in which I need to use bing APIs to search images from web and show them in book control in my silverlight browsing page.I want to add a web reference of bing APIs to my silverlight application, but if i tries to add it by going through solution explorer ->Add service reference, it throws an error.

Can anybody tell me how to add web reference to my application.

The web reference I want to add is

WSSF WCf async calls

acidburner — Fri, 27 Nov 2009 19:57:05 GMT

Hi everybody,

I'm struggling for 2 days know and I can't figure out how to do async calls with begin/endmethod.

I'm using WSSF and everything is set up (Datacontracts, Faultcontracts, ServiceContracts etc..). When I use a WinClient everything works fine, but if I use a silverlight client something goes wrong. I use the following Code in the client:

EmployeeService.EmployeeServiceContractClient proxy = new SlClientTest.EmployeeService.EmployeeServiceContractClient();
proxy.GetEmployeeCompleted += new EventHandler<SlClientTest.EmployeeService.GetEmployeeCompletedEventArgs>(proxy_GetEmployeeCompleted);

proxy.GetEmployeeAsync();

The proxy.GetEmployeeAsync() error is: No overload for method takes 0 arguments.

I've read a lot about proxys generated by VS or do it manually and about channell factories but I'm totaly lost at the moment. Who can help me out?

6            }

Question:
How to be sure that the application ready load the myList, to be read in Home.xaml.cs?
Tks.

WCF - Silverlight - Cross domain issues?

schinkowski — Wed, 18 Nov 2009 14:08:09 GMT

Hi,

I want to consume a WCF service from silverlight. I added a silverlight enabled wcf service to the web project and try to access it from silverlight but get the following exception.

System.ServiceModel.CommunicationException was unhandled by user code
Message="An error occurred while trying to make a request to URI 'http://localhost:50065/hackers_game/somaochuService.svc'. This could be due to attempting to access a service in a cross-domain way without a proper cross-domain policy in place, or a policy that is unsuitable for SOAP services. You may need to contact the owner of the service to publish a cross-domain policy file and to ensure it allows SOAP-related HTTP headers to be sent. This error may also be caused by using internal types in the web service proxy without using the InternalsVisibleToAttribute attribute. Please see the inner exception for more details."

I read a lot on this forum about similar issues, but could not resolve my problem.

The website has a static port number set and I created the "clientaccesspolicy.xml" and "crossdomain.xml" files and placed them in the root folder of the web project, in C:\inetpub\wwwroot, in the directory of the wcf service, but nothing worked.

When I use fiddler to see what's happening, I cannot see the transfer of these files. I also cannot see that the silverlight project tries to access the WCF service (not sure if I should see anything like that...).

Any ideas what mighht be causing this?

Thanks.

Retrieve the HTTP Error code instead of "NotFound" with WebClient

thibhen — Fri, 30 Oct 2009 09:07:21 GMT

Hello, I am trying to catch the error returned by an external Web server but Silverlight always returned a generic error message : "The remote server returned an error: NotFound.". I would expect to have something like "Error 500 : Internal server Error".

        WebClient client = new WebClient();
        client.DownloadStringAsync( "http://myurl" );
        client.DownloadStringCompleted += new DownloadStringCompletedEventHandler(
                delegate(object sender, DownloadStringCompletedEventArgs e)
                {
                    if (e.Error != null)
                    {
                        // The bad error message
                    }
                    else
                    {
                        // process content
                    }
                }
            );

How to retrieve correctly this error code ?

Accessing a WCF Service - keep getting the credentials prompt

Jean-Pierre Fouche — Thu, 26 Nov 2009 13:16:03 GMT

I have implemented Transport security as directed on msdn here : http://msdn.microsoft.com/en-us/library/cc949025.aspx It works in a Windows App, but not in Silverlight. I notice that the Authentication proxy does not send the authorization headers until the second post. i.e. First post - no auth headers Response from server is a challenge The browser throws the credentials prompt (aargh!) Silverlight client doe not get a chance to send the auth headers (it would normally send them). How do you get the authentication to work WITHOUT THE PROMPT?

Web Service Parser Error

gashgul — Wed, 25 Nov 2009 11:48:23 GMT

Hello !

I have a Parser Error when i call my Web Service.

The Web service works fine on local but not on-line .

I already search on forums, but i don't find the solution ... Can anyone help's me ?

I check the server ASP.NET version, it's 2.0

In Advance, Thanks to anyone who will help !

Here is the error message:

ClientHttp stack/service references/IIS

hwsoderlund — Mon, 23 Nov 2009 09:39:07 GMT

I'm accessing a WCF service hosted in IIS through the proxy code generated with the "add service reference" command. For security we rely on asp.net authentication. We also use some session variables. Of course, when I switch to the client http stack instead of the default browser http stack, this all fails because of missing cookies. I understand that I should be able to set the cookies manually, but exactly where would I do this? Obviously I cannot change the generated code as my changes would get overwritten every time I re-generate the proxy. So, is there a way of hooking into the request being sent over the wire and inserting the cookie values? Or perhaps I am on the wrong track altoghether and should choose another approach? Any suggestions are welcome.

Securing ASMX Service

Error Accessing a Silverlight Enable WCF service from Silverlight 3

Dan_dan — Tue, 17 Nov 2009 10:36:55 GMT

Hi all,

I have spent the better part of the day trying to solve this.

I have a silverlight 3 application that is using a WCF silvelight enabled service. When i run this using the test page on local host all works fine. If i then deploy on the production server that is on the intranet it fails. The error happens when i try and hit the WCF service from Silverlight.

I used fiddler to find out what is happening and i get a Http 500 internal server error reported by fiddler.
When i try and browse the service url from the browser that is looking at the production server it can succesfully see the service.

Also i made sure that the URL used in the service reference file is updated to point to the server. And nothing again.

If i use remote debugggin and attach debugger to the IE process i can step through the code and here is what gets thrown at me:
{System.Net.WebException: The remote server returned an error: NotFound. ---> System.Net.WebException: The remote server returned an error: NotFound.
   at System.Net.Browser.BrowserHttpWebRequest.InternalEndGetResponse(IAsyncResult asyncResult)
   at System.Net.Browser.BrowserHttpWebRequest.<>c__DisplayClass5.<EndGetResponse>b__4(Object sendState)
   at System.Net.Browser.AsyncHelper.<>c__DisplayClass2.<BeginOnUI>b__0(Object sendState)
   --- End of inner exception stack trace ---
   at System.Net.Browser.AsyncHelper.BeginOnUI(SendOrPostCallback beginMethod, Object state)
   at System.Net.Browser.BrowserHttpWebRequest.EndGetResponse(IAsyncResult asyncResult)
   at System.ServiceModel.Channels.HttpChannelFactory.HttpRequestChannel.HttpChannelAsyncRequest.CompleteGetResponse(IAsyncResult result)}

I am not sure what else to try.

I even tried to rename the .xap to zip and check the address there and its all fine.
This all runs on the intranet but i also placed a policy file on the remote server.
Nothing again.
Any pointers would be really really apreciated.
I am not sure why when on local host it is all good.
Looking forward to your response.

How to read xml file hosted on web server in silverlight

Pirate11 — Fri, 20 Nov 2009 12:25:53 GMT

I am facing this problem very often. I want my silverlight Game to read XML file which is hosted on a web server on a different domain.

I am not able to read this XML file and always end up making XML file a part of XAP package. (which i dont want)

My game will be hosted on different websites but i want to read XML file which is hosted on my website.

How to achieve this? I tried many methods posted in many threads on this website. Here is my code

private void btnload_Click(object sender, RoutedEventArgs e)
        {
            WebClient w = new WebClient();
            w.DownloadStringCompleted += new DownloadStringCompletedEventHandler(w_DownloadStringCompleted);
            w.DownloadStringAsync(new Uri(http://mywebsite.com/myxml.xml, UriKind.RelativeOrAbsolute));
        }

        void w_DownloadStringCompleted(object sender, DownloadStringCompletedEventArgs e)
        {
            if (e.Error == null)
                txtxml.Text = e.Result;
            else
                txtxml.Text = e.Error.ToString();
        }

but it gives my this exception : System.Security.SecurityException.

i understand that accessing cross-domanin files gives security exceptions, but i do not want that XML file in ClientBin. I want the data to be dynamic, so i need not re-publish my XAP file again and again.

I read other threads, they said to include ClientAccessPolicy file.. but it wasnt mentioned how to use it or where to put it.

Hope to get a solution. Thanks.

Sharepoint webservices from Silverlight

steveclements — Thu, 19 Nov 2009 14:09:28 GMT

I am accessing Sharepoint web services from a Silverlight application, I have put the clientaccesspolicy.xml file in the root of my Sharepoint site, so I can access fine.

What I would like to do though is hard code the user credentials so the web service always connects with the same user.

Is this possible and if so how?

Thanks in advance.

Debugging tips - read before posting

Yavor Georgiev - MSFT — Wed, 25 Nov 2009 01:33:02 GMT

Hi folks,

Here are some common things you should try before posting.

CommunicationException

System.ServiceModel.CommunicationException was unhandled by user code
Message="The remote server returned an error: NotFound."

If you get this error, then the WCF service is trying to tell you that something went wrong, but the full error information is not making it back to Silverlight. To fix this problem, add the following line to the MainPage constructor in your Silverlight application. This switches over to the new ClientHttp stack which fixes the problem (you can remove the line when you are done debugging).

WebRequest.RegisterPrefix("http://", WebRequestCreator.ClientHttp);

You may also need to find this line in your WCF service Web.config file, and change this value to true.

<serviceDebug includeExceptionDetailInFaults="true"/>

This should give you much more information in your Silverlight client about what's going wrong. Please remember to remove both of these changes once you are done debugging.

Next steps

If the above does not help, try the steps in the this tutorial in MSDN.

Hope this helps,
-Yavor

Problem debuging WCF service hosted in IIS using some references from other programs...help please...

PregnantBySilverlight — Tue, 24 Nov 2009 17:44:26 GMT

Hi,

I do have WCF service which is using references from my other programs. everything is pointing to the bin directory under my C drive, but because it's been hosted under IIS, first of all, I can't debug when I'm running the service from IIS, second of all, My references don't work.

I tried to copy all of the dlls under the IIS virutal directory, but still not working.

Also, I don't know how to attach the debugger for WCF and silverlight which are running from IIS.

any help would be greatly appreciated....thanks in advance

Error calling method on NPObject!

I am running Silverlight 3 RTM and Win7 and am using ADO.NET Data Services. I have two projects. First, I start my service in VS 2008 without degugging. Then I start up a second project, the web project for my Silverlight app. When I access the local server in IE, it works fine. But when I access it in Firefox, I get this exception and I never get any data.

Does Silverlight support WebHttpBinding(WCF) now?

I know SL2 only support BasicHttpBinding.

That is inconvenient to call a REST WCF!

Deployed Webservice not found

z00m — Wed, 18 Nov 2009 20:50:03 GMT

Hi there,

my webservice is working fine in my dev environment, but when I deploy it on a server (ISP) with IIS6 it is not working. I read a lot of threads and already created a crossdomain.xml, added the MIME type .svc as "application/octet-stream" and tried some other stuff i can't remember.

When I use Fiddler2, I can see that first I get a 302 statuscode when invoking the service and then a 404 statuscode. When I try to access the serivce directly in the Browser I get the same.

Since it's not my server and I don't have any rights I can't reregister .NET with "aspnet_regiis -i". But if you think it's my last chance I'll try to reach someone. What can I do ??

Thanks

proxy class is created implementing INotifyPropertyChanged by default

Midav — Mon, 23 Nov 2009 08:03:51 GMT

Hi,

I just started playing with SL and WCF. On the service side I have a simple class with a couple of properties. Everything works fine on the client side also. When I looked at the proxy code generated on the client, my class already was generated implementing

INotifyPropertyChanged interface. I thought I would have to write that code myself. Is this a standard SL behavior. Does this mean I never have to worry implementing this interface myself?

Thank you,

Midav

Problem with https ssl

PregnantBySilverlight — Wed, 18 Nov 2009 22:34:54 GMT

I have a simple WCF service hosted in IIS. When I change the configuration to use secure https, it doesn't work.When I run the service in the browser https://localhost/Service1.svc I get "The page cannot be found"....I do have SSL certificate installed in my machine.....what else is missing?

Please help....thanks in advance....

here is my code and my web.config file

====================================================================

namespace WcfService
{
    // NOTE: If you change the class name "Service1" here, you must also update the reference to "Service1" in Web.config and in the associated .svc file.
    public class Service1 : IService1
    {
        public string SayHello()
        {
            return "Hello";
        }
    }
}

====================================================================

namespace WcfService
{
    // NOTE: If you change the interface name "IService1" here, you must also update the reference to "IService1" in Web.config.
    [ServiceContract]
    public interface IService1
    {
        [OperationContract]
        string SayHello();

Context-Property in an WCF-Service?

Echo6 — Fri, 20 Nov 2009 13:55:54 GMT

Hello,

I have in my silverlight application a normal Webservice (.asmx) in which I get the IP-Address of the client.

*******************************************************************

string ip = this.Context.Request.UserHostAddress;

return ip;

*******************************************************************

This Code works so far, but now I would like to use a WCF-Service for it. When I use this code in my new WCF-Service, I don't have the possibility to access the "Context"-Property. How can I get an access to this property?

Thank you in advance for your answers!

Best Regards

Echo6

silverlight to MySQL using WCF

td.trinh — Thu, 19 Nov 2009 09:59:23 GMT

Hi, I am developing a silverlight Vista gadget and I want to get data from REMOTE LINUX MySQL server. My question is what are all the possible way to do that? ............................................................ ............................................................ I already can get data from WCF webservice and bind it my silverlight application but not sure how can I get data from MySQL server in Linux with WCF. Is there any example of doing that. ............................................................ ............................................................ I am new to WCF and .Net so another quick question is that is there any problem for me to deploy this silverlight vista gadget in any vista computer with the solution (silverlight - WCF - MySQL server). (or They need .NET 3.0 installed and anything else... ) Thank you very much

clientaccesspolicy.xml and crossdomain.xml not working

Rixy1 — Fri, 20 Nov 2009 10:37:46 GMT

Hi folks,

I'm attempting to deploy either of these two files on a development server running some Java web services that I want to call while debugging my Silverlight app on my local PC. Despite these files being fetched successfully by Silverlight, I am still getting the cross-domain error being reported. I've verified via Fiddler that the file contents are being returned successfully and compared contents of the files to lots of posts and can't find any errors with them. Here's the clientaccesspolicy.xml file:

<?xml version="1.0" encoding="utf-8"?>
<access-policy>
  <cross-domain-access>
	<policy>
	  <allow-from http-request-headers="*">
		<domain uri="*"/>
	  </allow-from>
	  <grant-to>
		<resource path="/" include-subpaths="true"/>
	  </grant-to>
	</policy>
  </cross-domain-access>
</access-policy>

Any suggestions greatly appreciated!

It's a good thing I don't have much hair, because otherwise my head would be quite sore right now (ignoring the headache I feel coming on!)

Thanks,
Rixy!

Edit: Incidentally, I'm currently using a secure connection on port 8443. Don't know if this has any impact on things, but from looking at references for the clientaccesspolicy.xml and crossdomain.xml files, this doesn't seem to be a problem.
