.net – WCF service with both basicHttpBinding and netTcpBinding; can’t access HTTP endpoint

I want to make available the same interface with a netTcpBinding and basicHttpBinding. I also wanna make available the wsdl for both endpoints. When I access http://localhost:9876/TestService/, I get the mex endpoint that has the information for the Tcp endoint at http://localhost:9876/TestService/?wsdl, but the address http://localhost:9876/TestService/ws does not respond, and I can't understand why. I have the base address, and the relative address. Can someone lend me a hand pointing out what's missing? Right now, I'm just trying to get working the TestImplementation service, and I haven't messed with the MessaginImplementation service.
