Do you have the ServiceMetaDataBehavior and Mex endpoint configured for your service
Below is an example
<?xml version="1.0" encoding="utf-8"?>
<configuration>
<system.serviceModel>
<services>
<service name="myService" behaviorConfiguration="MetadataBehavior">
<endpoint address="" binding="wsHttpBinding" contract="MyServiceContract.IMyService" />
<endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" />
</service>
</services>
<behaviors>
<serviceBehaviors>
<behavior name="MetadataBehavior">
<serviceDebug includeExceptionDetailInFaults="True" httpHelpPageEnabled="True" />
<serviceMetadata httpGetEnabled="True"/>
</behavior>
</serviceBehaviors>
</behaviors>
</system.serviceModel>
</configuration>
