Read the page above and you might think that your configuration file should look like this
<configuration>
 <system.serviceModel>
  <services>
   <service name="MyNameSpace.MyServiceType">
    <host>
     <baseAddresses>
      < baseAddress baseAddress="http://localhost:8000/MyService/"/>
      < baseAddress baseAddress="net.tcp://localhost:8010/MyService/"/>
     </baseAddresses>
     </host>
    <endpoint address="Calculator" binding="basicHttpBinding" contract="MyNamespace.IServiceContract" />
   </service>
  </services>
 </system.serviceModel>
</configuration>

But no… baseAddress element doesn’t work that way it works like this:
…
 <host>
  <baseAddresses>
   <add baseAddress="http://localhost:8000/MyService/"/>
   <add baseAddress="net.tcp://localhost:8010/MyService/"/>
  </baseAddresses>
 </host>
…
What clued me in was the initial bug at the top.  The hierarchy doesn't match properly.  After some random hunting around I saw some examples where the <add element is used and gave it a shot.  Bingo!
