Question

User88744855 posted

do we need use endpoint url to create proxy. just see one config entry
<service name="WCFService.Service" behaviorConfiguration="behaviorConfig">

<host>
  <baseAddresses>
    <add baseAddress="net.tcp://localhost:1645/ChatServer/"/>
    <add baseAddress="http://localhost:1648/ChatServer/"/>
  </baseAddresses>
  </host>
  <endpoint address="tcp"
                  binding="netTcpBinding"
                  bindingConfiguration="tcpBinding"
                  contract="ChatService.IChat"/>

 <endpoint address="net.tcp://localhost:1645/ChatServer/mex"
                  binding="mexTcpBinding"
                  contract="IMetadataExchange"/>

 </service>

why can't we create proxy giving the one base address like

http://localhost:1648/ChatServer/ ?? tell me reason.

if we add another mex endpoint in my exsisting config file like below one
<endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" />
then can we create proxy with url like http://localhost:1648/ChatServer/
please discuss.
