WCF net.tcp - connection rejected by the target machine

Question

I have a problem with Windows 8 x 64, as well as with Windows 7 x 64. I have a simple WCF service that uses net.tcp binding.

I wrote several articles to write this simple service, including the following on MSDN: Hosting and Using WCF Services

My service and configuration files are exactly the same as indicated in the previous article.

After installing this WCF service using InstallUtil.exe as a service window, I see that the service is installing correctly and it works without errors. I tried adding traces to the OnStart and OnStop methods of the Windows service and did not find anything wrong. As soon as I try to reference this endpoint from another solution, I will get the following error.

Failed to connect to net.tcp: // localhost: 8523 / Inbound. The communication attempt lasted for 00: 00: 00.9531494. TCP error code 10061: The connection could not be completed because the target machine actively refused it 127.0.0.1:8523.

I tried most of the messages related to this problem via the Internet, and I also tried to open firewalls, disable antivirus software, try different ports, explicitly create incoming and outgoing rules for these ports in the firewall, etc. I can’t access this Windows service that hosts my net.tcp based WCF service. TCP port sharing services and TCP list adapter services are enabled, and I also enabled the unnecessary Windows features needed to run these TCP services.
