Question

I have a simple test purpose WCF service. I’m trying to host it under IIS 7.5 ( Windows 7 ) but no luck so far. I’m getting error

Cannot obtain Metadata from net.tcp://localhost/TestApp2/MyService

I have a web site TestApp2 under Default Web Site, I enabled tcp on Default Web Site and TestApp2. Here is my web.config file, while I realize that this error simply states that I didn’t have endpoint for metadata exchange, I can’t see what’s the problem because I included endpoint for metadata exchange.

<system.serviceModel>
<services>
  <service behaviorConfiguration="ServiceBehavior" name="MyService">

    <endpoint address="net.tcp://localhost/TestApp2/MyService"
              binding="netTcpBinding"
              bindingConfiguration="PortSharingBinding"
              contract="II7WcfService.IService1" />

    <endpoint address="MEX"
              binding="mexTcpBinding"
              contract="IMetadataExchange" />

    <host>
      <baseAddresses>
        <add baseAddress="net.tcp://localhost/TestApp2/MyService" />
      </baseAddresses>
    </host>

  </service>
</services>
<bindings>
  <netTcpBinding>
    <binding name="PortSharingBinding" portSharingEnabled="true">
      <security mode="None"/>
    </binding>
  </netTcpBinding>
</bindings>
<behaviors>
  <serviceBehaviors>
    <behavior name="ServiceBehavior">
      <serviceMetadata httpGetEnabled="False" />
      <serviceDebug includeExceptionDetailInFaults="false" />
    </behavior>
  </serviceBehaviors>
</behaviors>

Thanks.

My guess is your service isn’t actually called MyService but rather it is in a namespace. This means your declared endpoints are not getting picked up, and the default ones (which doesn’t include IMetadataExchange) are being used instead.

Add the name of your namespace to the attribute in the config and it should work.
