Question

i’m trying to call a WCF service from my Silverlight 3 app.
But… when trying to create a ‘silverlight enabled wcf service’ in my web project, my VS2008 crashes during creating the item (i think while editing the web.config).

So i thought: let’s create a ‘normal’ wcf service, and manually edit it to be a ‘silverlight enabled webservice’.

So i wondered what the differences are, and second: why is there a difference between a service called from a silverlight app and a non-silverlight app?

This is what i have now for the binding (i have a service without an Interface contract, just a direct class exposed, to begin with):

<system.serviceModel>
        <behaviors>
            <serviceBehaviors>
                <behavior name="RadControlsSilverlightApp1.Web.GetNewDataBehavior">
                    <serviceMetadata httpGetEnabled="true" />
                    <serviceDebug includeExceptionDetailInFaults="false" />
                </behavior>
            </serviceBehaviors>
        </behaviors>
        <bindings>
            <customBinding>
                <binding name="customBinding0">
                    <binaryMessageEncoding />
                    <httpTransport />
                </binding>
            </customBinding>
        </bindings>
        <serviceHostingEnvironment aspNetCompatibilityEnabled="true" />
        <services>
            <service behaviorConfiguration="RadControlsSilverlightApp1.Web.GetNewDataBehavior"
             name="RadControlsSilverlightApp1.Web.GetNewData">
                <endpoint address="" binding="customBinding" bindingConfiguration="customBinding0"
                 contract="RadControlsSilverlightApp1.Web.GetNewData" />
                <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" />
            </service>
        </services>

    </system.serviceModel>

This one doesn’t work because when i add a reference to it from the silverlight app i get these messages:

(ps., the service can be started in the browser, i get this:

svcutil.exe http://localhost:9599/GetNewData.svc?wsdl

)

Answer 1

It seemed that there was another problem at hand, it was answered here

can i use a generic list in a WCF called from silverlight?
