I am fairly new to hosting web applications and web services. Though I was successful in hosting a web application, I am running into road block after road block when trying to host a WCF service with net.tcp binding.

My scenario is as follows, I have a hosted web application that needs to communicate with a hosted WCF service with net.tcp binding through IIS 7.5. As stated the web application is hosted fine and I can browse the web site. However, the web application makes services calls to the WCF service and I am getting the 'TCP error code 10061' message which I believe is due to my hosted WCF service not running. I think this is not running because I attempt to 'telnet localhost 808' to see if the WCF service is running and it is not. I've run through numerous online guides and I still have had no luck. I believe I may be doing something fundamentally wrong with me being a noob and all. I am able to host the service through VS2010 and run the web application and it works fine so I believe my bindings are correct. I've also enabled tcp protocols on both websites in IIS Manager.

So I guess my real question is what are the IIS Manager steps needed to host a WCF service with net.tcp binding? It appears to me that it is not possible to host a net.tcp service through IIS Manager by simply creating a website because IIS Manager wants to bind to an http port.

Here are some things to check:

  • Ensure the Net.Tcp Listener Adapter windows service is running
  • Ensure netTcp is listed as an enabled protocol for your website (In IIS Manager, go to Advanced settings for your site)
  • Ensure netTcp is listed as an enabled protocol for application (directory) that is hosting your services (In IIS Manager, go to the directory hosting your services and select Advanced Settings)
  • Ensure your IIS site has a binding for net.tcp, with the correct port number listed.

EDIT:
See the following MSDN page for enabling/using non-HTTP bindings in .Net 4 + IIS 7/7.5:
