What exactly do I need to do to host a WCF service in IIS 7.0 using netTcpBinding?

Hello Everyone:

I've been trying for more than a week without any success at all, to host a very simple HelloWorld-like wcf service using netTcpBinding.

With http, everything is ok. I can access my service even from a remote machine. But with tcp problems arise.

I have performed all the steps I'm supposed to, in order to host my service in WAS:

* .Net 3.0 Features are enabled, including http and non-http Activation

* I have granted 'Network Service' and 'IIS_IUSRS' the following permissions to the folder containing the site:

   - Read & Execute
   - List Folder Contents
   - Read

* Opened de ports 8100 and 8086 in the firewall.

* At IIS Manager/ Actions / Bindings the following bindings are set up:
  - http 8100:*  
  - net.tcp 8086:*

* At IIS Manager/ Manage Web Site / Advanced Settings, both, http and net.tcp protocols are enabled.

The original problem I had was that I was able to reach the service via http but when trying with tcp I got the following error:

"The message could not be dispatched because the service at the endpoint addres 'net.tcp://myDomain/HelloWorld.Hello.svc' is unavailable for the protocol address."

I found a post in this site whose author had the same problem and It was solved by reinstalling .net 3.0 features. So I tryed that. I also tryed to reinstall IIS 7.0 just in case.
Now, the situation is worse than it was at the begining. If I configure an endpoint with tcpBinding in my Web.Config I can't even reach my service at it's http address using IE!! I get the following message:

Could not find a base address that matches scheme net.tcp for the endpoint with binding NetTcpBinding. Registered base address schemes are [http].

The Web.Config file is as follows:


<?xml version="1.0" encoding="utf-8" ?>
<configuration>
 
   <system.web>    
     <compilation debug="true" />
  </system.web>
  <system.serviceModel>
     <services>
        <service behaviorConfiguration="HelloWorld.HelloBehavior"
                 
           name="HelloWorld.Hello">
           <host>
              <baseAddresses>
                 <add baseAddress="http://myDomain:8100/HelloWorld/" />
             <add baseAddress="net.tcp://myDomain:8086/HelloWorld/" />
              </baseAddresses>
           </host>          
         
           <endpoint address=""
                     binding="wsHttpBinding"
                     contract="HelloWorld.IHello"
                     bindingConfiguration="httpInseguro">
           </endpoint>

           <endpoint address=""
                     binding="netTcpBinding"
                     contract="HelloWorld.IHello"
                     bindingConfiguration="netTcpInseguro">
           </endpoint>
     
         
           <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" />

        </service>
     </services>
   
    <bindings>

      <wsHttpBinding>
        <binding name ="httpInseguro">
          <security mode ="None" />
        </binding>        
      </wsHttpBinding>
     
      <netTcpBinding>
        <binding name ="netTcpInseguro">
          <security mode ="None" />
        </binding>        
      </netTcpBinding>

    </bindings>

and the .svc file is like this:

<% @ServiceHost Service="HelloWorld.Hello" %>


Could anyone please give me a clue about what's going on? I really don't know what else to do. This is being a real headacke becasuse using http binding is not an option.
Thanks in advance.

Check below points.

1. You should have a MEX for tcp also. add this. <endpoint address="mextcp" binding="mexTcpBinding" contract="IMetadataExchange"/>
2. there is no port information available in your request.
3. Why you are having 2 base addresses for your service ? Are hosting your tcp service to the proper address as mentioned in the config file and also your client requesting the to the same URL ?

Same sample is tried by some one else also..check this link.

Hello apeter,

I didn't know about the need to have the mex. I'll try that.
The port information is provided at both sides and it's correct. I've also hosted the service inside a console app. and everithing is Ok even with netTcpBinding. The problem is with IIS + netTcpBinding.
I have 2 base addresses because is easier to check if the service is up using http.
Thank you.
Best wishes.

Hello apeter,

I don't know how to thank you!! If I only discoverd this web before It would have saved me 2 weeks of work.

The problem was the missing endpoint:

<endpoint address="mextcp" binding="mexTcpBinding" contract="IMetadataExchange"/>

Thank you very much.

Best wishes,

David
