This weird Error was appearing from one day before posting this post. Previously it was working fine, but not now.
At one movement restarting the system, the error disappears and able to access the application.
and after again rebooting the system the error begins to appear without knowing the root cause.
Enabled Protocols: `net.tcp,http`
I could able to browse the below link
  • http://localhost/TNA/TAServices/AuthenticationManager.svc
  • http://username.domainname.com/TAServices/AuthenticationManager.svc?wsdl
  • http://username.domainname.com/TAServices/AuthenticationManager.svc?singleWsdl
Here is the below snippet which causes an exception
  1. objCheckUserLoginResponse = AuthenticationManagerClient.Check(objCheckUserLoginRequest, objCustomer);  
Exception:
The message could not be dispatched because the service at the endpoint address 'net.tcp://localhost/TAServices/AuthenticationManager.svc' is unavailable for the protocol of the address.
System.ServiceModel.EndpointNotFoundException: The message could not be dispatched because the service at the endpoint address 'net.tcp://localhost/TNA/TAServices/AuthenticationManager.svc' is unavailable for the protocol of the address.

Without knowing the cause I was not able to do anything.
Please suggest in resolving `EndpointNotFoundException` issue wrt to code or from windows 10 (1903)
