"Add Service Reference" is not supported in MD yet. And yes, the 
existing one is for Sys.Web.Services, not WCF.

WSHttpBinding is not supported. And...

I found something is wrong with mere "?wsdl" query in the latest code. 
It is very tricky to handle such a request and I had to make a lot of 
attempts (since both service contract itself and WSDL request contract 
conflict at the same URI just by different at query parameter, which 
cannot be handled at service host internals, namely, ChannelDispatcher 
and EndpointDispatcher - in short, bad design), so it is likely broken now.
As a workaround, you can probably handle it by configuring it like:
<serviceMetadataBehavior httpGetUrl="wsdl" httpGetEnabled="true" />
