WCF System.ServiceModel.Dispatcher.NetDispatcherFaultException

[ABBhagwat]

Hi ,

I have written a simple function GetRuleDetail in WCF returning below class

[DataContract]

public class MyRule


{

[DataMember]

public string st1;


[DataMember]

public string st2;

}


Now I am using basic http binding my web.config(wcf) is as below

<system.serviceModel>


<services>

<service name="MyService.MyCmdService

<endpoint address="" binding="wsHttpBinding" bindingConfiguration="secureHttpBinding" contract="MyService.IMyCmdService

<identity>

<dns value="localhost" />

</identity>

</endpoint>

<endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" />

<host>

<baseAddresses>

<add baseAddress="http://localhost/MyService/MyCmdService/" />

</baseAddresses>

</host>

</service>

</services>

<bindings>

<wsHttpBinding>

<binding name="secureHttpBinding

<security mode="Message

<message clientCredentialType="Windows"/>

</security>

</binding>

</wsHttpBinding>

</bindings>

<behaviors>

<serviceBehaviors>

<behavior>

<!-- To avoid disclosing metadata information, set the value below to false and remove the metadata endpoint above before deployment -->

<serviceMetadata httpGetEnabled="true"/>

<!-- To receive exception details in faults for debugging purposes, set the value below to true. Set to false before deployment to avoid disclosing exception information -->

<serviceDebug includeExceptionDetailInFaults="false"/>

</behavior>

</serviceBehaviors>

</behaviors>


<serviceHostingEnvironment multipleSiteBindingsEnabled="true" />

</system.serviceModel>


My client app.config is as below


<system.serviceModel>


<bindings>

<wsHttpBinding>

<binding name="WSHttpBinding_IMyCmdService Service" closeTimeout="00:01:00"

openTimeout="00:01:00" receiveTimeout="00:10:00" sendTimeout="00:01:00"

maxBytesPerRead="4096" maxNameTableCharCount="16384" />

<reliableSession ordered="true" inactivityTimeout="00:10:00"

<security mode="Message

<transport clientCredentialType="Windows" proxyCredentialType="None"

realm="" />

<message clientCredentialType="Windows" negotiateServiceCredential="true"

algorithmSuite="Default" />

</security>

</binding>

</wsHttpBinding>

</bindings>

<client>

<endpoint address="http://localhost/Mycmd/ExchangeCmdletService.svc"

binding="wsHttpBinding" bindingConfiguration=" WSHttpBinding_IMyCmdService "

contract="MyService.IMyCmdService " name=" WSHttpBinding_IMyCmdService

<identity>

<dns value="localhost" />

</identity>

</endpoint>

</client>

</system.serviceModel>


Now when I run this I get below error:

at System.ServiceModel.Dispatcher.DataContractSerializerOperationFormatter.DeserializeParameterPart(XmlDictionaryReader reader, PartInfo part, Boolean isRequest)

at ClientExportRule.CybExchangeService.ExchangeCmdletServiceClient.GetRuleDetails(System.String)

at ClientExportRule.Program.Main(System.String[])



If I move setup(both client and wcf hosting) to another machine (same os 2008 r2 64 bit) it works fine.


Below is client sied code

ExchangeCmdletServiceClientclient = newExchangeCmdletServiceClient("WSHttpBinding_IExchangeCmdletService");


MyRule rule = client.GetRuleDetails();

Any idea what’s wrong?
