title: The protocol 'net.tcp' is not supported issue regarding WCF
body: <p>first i create a WCF service application where svc file is created. then i write my small service related code. <strong>when i hit F5 then wcf test client appear fine and when i select svc file and select view in browser option then everything works fine</strong>. initially i have only one endpoint in config file...that is <strong>wsDualHttpBinding</strong> then everything working fine.</p>
  
  <p>the moment i add another endpoint called <strong>netTcpBinding</strong> then problem start. after adding netTcpBinding endpoint in config file and when i try to browse svc file again in browser then i got error message called <strong>The protocol 'net.tcp' is not supported</strong> and when i hit F5 then wcf test client show error message called <code>** Cannot obtain Metadata from http://localhost:30996/ChatService.svc**</code></p>
  
  <p>i just do not understand why it happens when i add netTcpBinding. onething i like to say that i have not hosted my service anywhere. i just create WCF service application and add all the entries in web.config file and just press F5. is this the reason i am getting error because i have not hosted my services anywhere?</p>
  
  <p>so here is my config details as follows</p>
