Our application is hosted in IIS 7.0. It exposes endpoints over net.tcp protocol. But we kept running into the following exception:
EndpointNotFoundException: The message could not be dispatched because the service at the endpoint address 'net.tcp://localhost/xxx/service.svc' is unavailable for the protocol of the address.
We have checked the following places for possible causes.
I have tried to reset the IIS after checking all the above places. Still not working.
This is killing me. Hope someone could give me some hints.
I have searched a lot. Seems this is a very common issue which hasn't be perfectly solved. I think it's time to end this pain in ass.
Many thanks!

In the Name column of the list of services, right-click the Net. Tcp Port Sharing Service, and select Properties from the menu. To enable the manual start-up of the service, in the Properties window select the General tab, and in the Startup type box select Manual, and then click Apply.
Windows Communication Foundation (WCF) provides a new TCP-based network protocol (net. tcp://) for high-performance communication. WCF also introduces a new system component, the Net. TCP Port Sharing Service that enables net. tcp ports to be shared across multiple user processes.
Windows Communication Foundation (WCF) uses a Windows service called the Net. TCP Port Sharing Service to facilitate the sharing of TCP ports across multiple processes.
The TCPActivation sample demonstrates hosting a service that uses Windows Process Activation Services (WAS) to activate a service that communicates over the net. tcp protocol. This sample is based on the Getting Started.
It is hard to say but on what port are you trying to connect?
Make sure that port is available and nothing else is using it.
If you are using a proxy you should add the below as well:
......
<httpTransport
maxBufferPoolSize="4194304"
maxBufferSize="1048576"
maxReceivedMessageSize="1048576"
proxyAddress="http://127.0.0.1.:8888
useDefaultWebProxy="false"
/>
</binding>
</customBinding>
