Question

I get this error trying call my service in WcfTestClient

My config:

 <services>
      <service behaviorConfiguration="MetadataBehavior" name="ServiceModel.Service">
        <endpoint address="soap" binding="basicHttpBinding" name="Soap"
          contract="ServiceModel.IService"  />
        <endpoint address="rest" behaviorConfiguration="jsonBehavior"
          binding="webHttpBinding" bindingConfiguration="webHttpBindingSettings"
          name="Json" contract="ServiceModel.IService" />
        <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" />
        <host>
          <baseAddresses>
            <add baseAddress="http://dev.add.com/Service.svc/" />
          </baseAddresses>
        </host>
      </service>
    </services>
    <behaviors>
      <serviceBehaviors>
        <behavior name="MetadataBehavior">
          <serviceDebug includeExceptionDetailInFaults="true" />
          <serviceMetadata httpGetEnabled="true" />
        </behavior>
      </serviceBehaviors>
      <endpointBehaviors>
        <behavior name="jsonBehavior">
          <webHttp automaticFormatSelectionEnabled="true" helpEnabled="true"/>
        </behavior>
      </endpointBehaviors>
    </behaviors>

Why I get this error, it is connected with this property set for json endpoint ?

Answer 1

My mistake. I was checking that REST response Message contains AutomatedFormatSelectionContentTypePropertyName property, but in SOAP call it not contains it and fire error.

so I change this

if (OperationContext.Current.OutgoingMessageProperties.ContainsKey("AutomatedFormatSelectionContentTypePropertyName"))
            {

            }

to this

if (OperationContext.Current.OutgoingMessageProperties != null && OperationContext.Current.OutgoingMessageProperties.ContainsKey("AutomatedFormatSelectionContentTypePropertyName"))
            {

            }
