    text
    copied!<p>I'm trying to host a WCF service with net.tcp binding within an IIS 7.5 site on Windows 7, 64-bit. Sadly, the service is unreachable. In fact, opening a connection to the TCP port using telnet even fails.</p> <p>Here's what my system.serviceModel section of the web.config for the site looks like:</p> <pre><code>&lt;system.serviceModel&gt; &lt;behaviors&gt; &lt;serviceBehaviors&gt; &lt;behavior name="DefaultServiceBehavior"&gt; &lt;serviceMetadata httpGetEnabled="false" /&gt; &lt;serviceDebug includeExceptionDetailInFaults="true" /&gt; &lt;dataContractSerializer maxItemsInObjectGraph="2000000" /&gt; &lt;/behavior&gt; &lt;/serviceBehaviors&gt; &lt;/behaviors&gt; &lt;services&gt; &lt;service behaviorConfiguration="DefaultServiceBehavior" name="FooService"&gt; &lt;endpoint binding="netTcpBinding" bindingConfiguration="service" name="service" contract="IFoo" /&gt; &lt;endpoint binding="mexTcpBinding" bindingConfiguration="DuplexBinding" contract="IFoo" /&gt; &lt;host&gt; &lt;baseAddresses&gt; &lt;add baseAddress="net.tcp://127.0.0.1:9000/service"/&gt; &lt;/baseAddresses&gt; &lt;/host&gt; &lt;/service&gt; &lt;/services&gt; &lt;bindings&gt; &lt;netTcpBinding&gt; &lt;binding name="service" portSharingEnabled="true"&gt; &lt;readerQuotas maxDepth="32" maxStringContentLength="8192" maxArrayLength="16384" maxBytesPerRead="4096" maxNameTableCharCount="16384" /&gt; &lt;security mode="None"/&gt; &lt;/binding&gt; &lt;binding name="DuplexBinding"&gt; &lt;reliableSession enabled="true"/&gt; &lt;security mode="None"/&gt; &lt;/binding&gt; &lt;/netTcpBinding&gt; &lt;/bindings&gt; &lt;/system.serviceModel&gt; </code></pre> <p>In IIS Manager, I set up a site with an App Pool running under the identity of NETWORK SERVICE, with the v4.0 .NET Framework and an integrated pipeline. There is one binding for the site with a type of <code>net.tcp</code> and "Binding Information" set to <code>9000:*</code>.</p> <p>Under my computer's services, I started the previously stopped "Net.Tcp Listener Adapter" and "Net.Tcp Port Sharing Service" services and made them both start up automatically. I also ensured that "Windows Communication Foundation Non-HTTP Activation" was installed.</p> <p>What else do I have to do to get IIS/WCF/WAS/whatever to listen on port 9000 so my service can be activated and invoked?</p> <p><em>My question is similar to <a href="https://stackoverflow.com/questions/7181011/host-wcf-service-with-net-tcp-binding-through-iis-manager-7-5">Host WCF service with net.tcp binding through IIS Manager 7.5</a>, but the OP was not registered, and his question was not answered. I'm opening this question so I can post my own details.</em></p> <p><strong>Update</strong></p> <p>I've found some additional clues. I decided to add a second binding so I can work with HTTP bindings while trying to figure out the net.tcp issues. Now, when I try to access the HTTP endpoint, I get this error</p> <blockquote> <p>Could not find a base address that matches scheme net.tcp for the endpoint with binding NetTcpBinding. Registered base address schemes are [http]</p> </blockquote> <p>I very clearly <em>have</em> bindings for both HTTP and net.tcp here:</p> <pre><code>&lt;baseAddresses&gt; &lt;add baseAddress="net.tcp://localhost:9000/"/&gt; &lt;add baseAddress="http://localhost:8050/"/&gt; &lt;/baseAddresses&gt; </code></pre> <p>So the phrase "Registered base address schemes" has me worried; is there something additional I have to do to allow my site to support the net.tcp scheme?</p>
