clientaccesspolicy.xml is needed only if ur web service is gonna be accessed by some other domains right.....or do we need it everytime??

Thank you for this interesting article. I have what is probably more of a Visual Studio question than a Silverlight question, so I hope it is appropriate here. In the screen grab after you added the service reference, we see all the leaf nodes of the DateTimeWebService in the Solution Explorer tree. I only see the parent node in my view.

How is it possible to enable viewing of the leaf nodes in Visual Studio? I explored for this feature but could not find it. Thanks in advance!

Good example, thanks. I only needed a hint to put 2 and 2 together.

Lazaro and GaryB

I also had a same problem and solved it by telling VS to use Local IIS Web Server instead of built in Cassini. It looks to me ports needs to be defined in the policy files. My files are as follows:

clientaccesspolicy.xml



        http://*/>







crossdomain.xml

http://www.macromedia.com/xml/dtds/cross-domain-policy.dtd">

PS. I am using Win7 with IIS7.5 (default with Win7).

Hope it helps.

Every article I see (starting with WCF and now this Silverlight/ASMX) uses localhost for the service domain. That is just not complete or real-world. Could someone post a sample of working code that uses two domains, one for the service and one for the client? Isn't that how services are supposed to work?

Nevertheless I am getting the same message Lazaro pasted above even on localhost. After figuring the client web config and the clientaccesspolicy I am stuck with that message.

Is this thread still active??

Your step by step is incomplete and makes a lot of assumptions. Please do a better job next time. From my experience and other comments here, you have left out a lot of details .-(

Hi i'm really confused on silverlight 2 and the webservice endpoint address.

When you add a reference in a silverlight project in visual studio to a webservice it uses the localhost address

eg. http://localhost/Application.Web/Webservice.svc

Now because the silverlight app is running on the client this means the client will try to access the service on their machine (not the server address). If i change this to a dns address then the service asks for the username and password. I cant seem to get around this. Can anyone help please? Thanks Steve

Great article - thanks. I would like to call asmx web services which require basic authentication (username/password) - however I am not sure how to set the credentials when calling the web services from the WCF client in Silverlight. Can you povide and guidance?

I have downloaded the code, build it and run it without problems. Make sure that you set one of the test pages in the WebSite project as start page. If you use the automatically generated TestPage in the Bin/Debug directory it would throw this exception, the automatically generated pages just don't work with services and not only with them and the reason is that they are opened not as http://, but as file:///. Also I tried to run it without starting the ASP.NET Development Server (Port 54602) - the service is hosted there, and it raised the exception that you have encountered. So look if both development servers (port 54602 for the service and port 55461 for the web site) are running and if not, maybe this is the key to your problem. ;)

Hello...great article...but I have some problems with security....

An error occurred while trying to make a request to URI 'http://localhost:54602/DateTimeWebService.asmx'. 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. Please see the inner exception for more details.

I download your code and open it in Visual Studio and build....nothing more....do you iluminate me...

Thanks

Hi Dee!

You are exactly correct w.r.t. that error. What i mentioned was related to WSE Web Service consumption by Silverlight Application.

RE: Consuming ASMX Web Services with Silverlight 2

Dee — Tue, 14 Oct 2008 12:45:17 GMT

Found the reason - Silverlight does not support Dataset class - Does not allow one to add System.Data as a reference. Once I commented out the web methods that used the Dataset class, the compile worked.

RE: Consuming ASMX Web Services with Silverlight 2

Dee — Tue, 14 Oct 2008 11:06:33 GMT

I am getting the same problem mentioned by Angelina.
Added Service Reference to an existing Web Service and tried to compile. Thats all - nothing else. And I get this error:
"The type or namespace name 'schema' could not be found (are you missing a using directive or an assembly reference?) ".
Should any special settings be applied ?
It seems like Angelina solved the problem "by taking the proxy of the WS in the Silverlight host." in the post above. What does that mean ??

RE: Consuming ASMX Web Services with Silverlight 2

Enrai — Tue, 07 Oct 2008 07:01:50 GMT

Looking at the error message I think that the problem might be in the ServiceReferences.ClientConfig file. Check if it's not missing in the project where you reference your services.

Fiannolo — Mon, 06 Oct 2008 09:02:54 GMT

Hi, first really thanks for your great work. I'm trying to modify your code and i have a big exception and i dont have idea. Can you help me?

this is the exception:

[Xml_CannotFindFileInXapPackage]

Argumentos:ServiceReferences.ClientConfig

Las cadenas de recursos de depuración no están disponibles. La clave y los argumentos suelen proporcionar suficiente información para diagnosticar el problema. Vea http://go.microsoft.com/fwlink/?linkid=106663&Version=2.0.30523.8&File=System.Xml.dll&Key=Xml_CannotFindFileInXapPackage.

I create a new silverlight class library and try to implement MVP pattern. calling the presenter method in the onclick button event and cut the code of the call to the web service and paste it in the presenter method.

This error throw the exception when the system call de constructor of the web service proxy class.

Sorry for my poor english. i'm trying to speak english to write it. and thanks for your work again. From venezuela.

Angelina — Mon, 06 Oct 2008 04:58:23 GMT

Thank you for your reply. Now i am able to get in connect with WSE enabled WS through WCF by taking the proxy of the WS in the Silverlight host.

I don't think that this article can be connected with the security in SIlverlight, so it's not very proper to post it as a comment here, but expect an article soon that will be focused on that. ;)

And about your question about the WSE 3.0 web services and Silverlight, which I have missed, I'll try to figure out how it's done when I have some time and will gladly share it with you ;)

RE: Consuming ASMX Web Services with Silverlight 2

Angelina — Fri, 19 Sep 2008 05:10:29 GMT

I want to know more about the security in silverlight Application as i have come across something called silverlight spy which can get all the details from the xap file of any silverlight application. Do share your thoughts on this.

RE: Consuming ASMX Web Services with Silverlight 2

Angelina — Wed, 27 Aug 2008 03:11:12 GMT

Is it possible to consume WSE 3.0 enabled webservice from Silverlight Application? If so, how?

RE: Consuming ASMX Web Services with Silverlight 2

Angelina — Tue, 26 Aug 2008 23:32:53 GMT

Hi Emil!

I am consuming simple web service of ASP.Net which has System.Web.Services.Protocols namespace. Whereas silvelright supports System.ServiceModel and hence tell me whether i can do this kind of consumption. Source code that gives me that error is as follows:

public partial class FetchResponseFetchResult : object, System.ComponentModel.INotifyPropertyChanged {private schema schemaField;private System.Xml.Linq.XElement anyField;/// XmlElementAttribute(Namespace="http://www.w3.org/2001/XMLSchema", Order=0)]public schema schemaget {return this.schemaField;set {this.schemaField = value;this.RaisePropertyChanged("schema"); }}

Hi Angelina,

Could you paste the source code the gives you this error so I can help you?

RE: Consuming ASMX Web Services with Silverlight 2

Angelina — Tue, 26 Aug 2008 07:32:26 GMT

What should i do for the above error?

RE: Consuming ASMX Web Services with Silverlight 2

Angelina — Tue, 26 Aug 2008 07:31:37 GMT

I am getting this error:

Error 3 The type or namespace name 'schema' could not be found (are you missing a using directive or an assembly reference?) D:\SilverLight Practice Using VS\TestWCF\TestWS\Service References\ServiceReference2\Reference.cs 41 17 TestWS

When adding a Service reference the studio also automatically creates a ServiceReferences.ClientConfig file, where the end points and the bindings are defined.

See if if you have this file in the project where you have added your service reference, if not, delete the reference and add it again it should be created automatically. If the file is available but there are no settings for the particular service in it, try to update the service or delete the reference and the file and than to add the reference again.

The code in the client config file should look like that:

<configuration>

    <system.serviceModel>

        <bindings>

            <basicHttpBinding>

                <binding name="DateTimeWebServiceSoap" maxBufferSize="65536"

                    maxReceivedMessageSize="65536">

                    <security mode="None" />

                binding>

            basicHttpBinding>

        bindings>

        <client>

            <endpoint address="http://localhost:54602/DateTimeWebService.asmx"

                binding="basicHttpBinding" bindingConfiguration="DateTimeWebServiceSoap"

                contract="DateTimeServiceSample.DateTimeWebService.DateTimeWebServiceSoap"

                name="DateTimeWebServiceSoap" />

        client>

    system.serviceModel>

configuration>

The end point is defined in the client element. I've tried to run the application without the information for the end point and it threw the same exception. So I think that the problem is in this file.

Hi, Ive tried your code but im getting this error in this line:

Dim service As New ServiceReference1.Service1SoapClient()

Could not find default endpoint element that references contract 'SilverlightApplication2.ServiceReference1.Service1Soap' in the ServiceModel client configuration section. This might be because no configuration file was found for your application, or because no endpoint element matching this contract could be found in the client element.

What else im a missing here?
