Hi all,
Im using silverlight with wcf. I have the business logic written in the wcf which will connect to database fetch the required data based on the search criteria. When I pass more than 191 records to the client
(i.e)

void svc_officeCon_gettotalattendhrsCompleted(object sender, gettotalattendhrsCompletedEventArgs e)

In the above event(e.result) im getting "Target Invocation exception".
If i pass less than 190 rows im not getting any error. I use Ilist<myclass> to store and pass the data from server to client. And Im using ms sql server 2008 as my database. Is there any limit for IList?
Can any 1 suggest me what will be problem?
Thanks in advance

Here is my webconfig.

C#

<?xml version="1.0"?>

<configuration>
  <connectionStrings>
    <add name="ConnectionString" connectionString="Data Source=testserver;Initial Catalog=Database;User ID=sa;Password=sa"/>
     </connectionStrings>

  <system.web>
    <compilation debug="true" targetFramework="4.0"/>
  <httpRuntime maxRequestLength="2097151" />
  </system.web>


  <system.serviceModel>
    <serviceHostingEnvironment multipleSiteBindingsEnabled="true" aspNetCompatibilityEnabled="true" />
    <bindings>
      <basicHttpBinding>         
        
        <binding name="PictureBinding" maxReceivedMessageSize="2147483647" maxBufferSize="2147483647">
          <readerQuotas maxArrayLength="2000000" maxStringContentLength="2000000"/>        
        </binding>       
      </basicHttpBinding>
    </bindings>  
    <behaviors>
      <serviceBehaviors>
        <behavior name="Myproject.Web.ImageServiceBehaviour">
          <serviceMetadata httpGetEnabled="true" />
          <serviceDebug includeExceptionDetailInFaults="true" />
        </behavior>
        <behavior name="">
          <serviceMetadata httpGetEnabled="true" />
          <serviceDebug includeExceptionDetailInFaults="true" />
        </behavior>
      </serviceBehaviors>
    </behaviors>
    <services>
      <service behaviorConfiguration="Myproject.Web.ImageServiceBehaviour" name="Myproject.Web.wcfService">
        <endpoint address="" binding="basicHttpBinding" bindingConfiguration="PictureBinding" contract="Myproject.Web.IwcfService">
          <identity>
            <dns value="localhost"/>
          </identity>
        </endpoint>
      </service>
    </services>
  </system.serviceModel>
  <system.webServer>
    <modules runAllManagedModulesForAllRequests="true"></modules>
  </system.webServer>

</configuration>

And below is my client Service.

<configuration>
    <system.serviceModel>
        <bindings>
            <basicHttpBinding>
                <binding name="BasicHttpBinding_IwcfService" maxBufferSize="2147483647"
                    maxReceivedMessageSize="2147483647">
                    <security mode="None" />
                </binding>
            </basicHttpBinding>
          
        </bindings>
      
        <client>
            <endpoint address="http://localhost:2466/wcfService.svc"
                binding="basicHttpBinding" bindingConfiguration="BasicHttpBinding_IwcfService"
                contract="ServiceReference.IwcfService" name="BasicHttpBinding_IwcfService" />
        </client>
    </system.serviceModel>
</configuration>

have you tried my solution by adding dataContractSerializer?

Saranya811 21-Sep-12 3:51am

I added to web.config. But im not able to add in clientconfig. It gives me "The element system.serviceModel has invalid child element behviors".

Santhosh Kumar Jayaraman 21-Sep-12 4:22am

thats because WCF concept of behaviors doesn't exist in the Silverlight 4

Santhosh Kumar Jayaraman 21-Sep-12 4:24am

And are you still getting the error?

Saranya811 21-Sep-12 4:31am

Thank you so much for the solution. I have added the "datacontractserializer maxitemsinobjectgraph="2147483647" to my web config which was missing. Now it executes perfect. I have not changed any code in my clientconfig. Thank you once again.

and this is how i solved it

In client side added a behavior configuration.

XML

<system.serviceModel>
        <behaviors>
            <endpointBehaviors>
                <behavior name="maxItems">
                    <dataContractSerializer maxItemsInObjectGraph="2147483646"/>
                </behavior>
            </endpointBehaviors>
        </behaviors>

and give this behavior configuration in End point

and in server side

XML

<behavior name="ServiceBehavior">
         <dataContractSerializer maxItemsInObjectGraph="2147483647" />
         <serviceMetadata httpGetEnabled="true" />
         <serviceDebug includeExceptionDetailInFaults="true" />
       </behavior>

and added this behavior to the service endpoint.. try this
