Hosting a WCF service with Net.TCP - wcf

Question

I am totally new to this and trying to host the simplest WCF service with a net.tcp binding
I have Windows 7 Professional and IIS7 and have enabled NON http activation.
I start a new WCF Service application
project in vs2010 and compile it.
NOHTING ELSE!
I delete all my IIS
Websites and add a new called WCFHost
I open up WcfTestClient.exe and adds
http://localhost/Service1.svc the application finds it
The Web.config looks like this (untouched)
<system.serviceModel>
<services>
<service name="WcfService2.Service1" behaviorConfiguration="WcfService2.Service1Behavior">
<endpoint address="" binding="wsHttpBinding" contract="WcfService2.IService1">
<!--
Upon deployment, the following identity element should be removed or replaced to reflect the
identity under which the deployed service runs. If removed, WCF will infer an appropriate identity
automatically.
-->
<identity>
<dns value="localhost"/>
</identity>
</endpoint>
<endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange"/>
</service>
</services>
<behaviors>
<serviceBehaviors>
<behavior name="WcfService2.Service1Behavior">
<!-- To avoid disclosing metadata information, set the value below to false and remove the metadata endpoint above before deployment -->
<serviceMetadata httpGetEnabled="true"/>
<!-- To receive exception details in faults for debugging purposes, set the value below to true. Set to false before deployment to avoid disclosing exception information -->
<serviceDebug includeExceptionDetailInFaults="false"/>
</behavior>
</serviceBehaviors>
</behaviors>
</system.serviceModel>
So far, so good. But what about that net.tcp binding. I add the "enabledProtocols" attribute so my applicationHost.config looks like this
<site name="WCFHOST" id="3">
<application path="/" applicationPool="WCFHOST" enabledProtocols="http,net.tcp,net.pipe,net.msmq">
<virtualDirectory path="/" physicalPath="C:\Prosjekter\temp\TestService\TestService" />
</application>
<bindings>
<binding protocol="net.tcp" bindingInformation="808:*" />
<binding protocol="http" bindingInformation="*:80:" />
</bindings>
</site>
Then I go to the IIS WCFHost website and add binding net.tcp 808:*
And then I modify my web.config for the WCF Service to look like this. (just changed the binding on the endpoints)
<system.serviceModel>
<services>
<service name="WcfService2.Service1" behaviorConfiguration="WcfService2.Service1Behavior">
<!-- Service Endpoints -->
<endpoint address="" binding="netTcpBinding" contract="WcfService2.IService1">
<!--
Upon deployment, the following identity element should be removed or replaced to reflect the
identity under which the deployed service runs. If removed, WCF will infer an appropriate identity
automatically.
-->
<identity>
<dns value="localhost"/>
</identity>
</endpoint>
<endpoint address="mex" binding="mexTcpBinding" contract="IMetadataExchange"/>
</service>
</services>
<behaviors>
<serviceBehaviors>
<behavior name="WcfService2.Service1Behavior">
<!-- To avoid disclosing metadata information, set the value below to false and remove the metadata endpoint above before deployment -->
<serviceMetadata httpGetEnabled="true"/>
<!-- To receive exception details in faults for debugging purposes, set the value below to true. Set to false before deployment to avoid disclosing exception information -->
<serviceDebug includeExceptionDetailInFaults="false"/>
</behavior>
</serviceBehaviors>
</behaviors>
</system.serviceModel>
When I now try to add the service net.tcp://localhost:808/Service1.svc in my WcfTestClient.exe I get the error
Error: Cannot obtain Metadata from net.tcp://localhost/Service1.svc
TCP-errorcode 10061: No connection could be made because the target machine actively refused it.... 127.0.0.1:808
My firewall is turned off.
I have seen one thing, though.. when using netstat -a the 808 port is not listed there.. should it?
Can someone help me just creating my first WCF service with nettcp binding?

Answer 1

As Tocco says, check that the service is running. You can do this by checking:
netstat /an | find /i "808 "
And it should show:
TCP 0.0.0.0:808 0.0.0.0:0 LISTENING
TCP [::]:808 [::]:0 LISTENING
if the service is running correctly.
To get it to start if it's not already working, you can issue:
sc start NetTcpActivator
from the command line to ttry to start it.
Even before that, make sure that the non-HTTP activation windows components are installed.
Also check that the services are actually running. I had a problem where they would not necessarily start after a reboot.

Answer 2

The net.tcp bindings are enabled on IIS for requests on 808?
Check it on IIS manager / bindings.
See it

Answer 3

I had the same error message and resolved it by not only creating a TCP binding on the site as follows:
But also enabling the net.tcp protocol in Advanced Settings:
