问题
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/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
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/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)
回答1:
I had solved this issue by releasing OneApp.IGCC.WinService.exe which had occupied the port 808 after Intel® Graphics Driver update was initiated. But it sounds weird, so check whether SMSvcHost.exe is listing to 808 port.
C:\Windows\system32>netstat -ano | find "808"
TCP 0.0.0.0:808 0.0.0.0:0 LISTENING 4356
TCP [::]:808 [::]:0 LISTENING 4356
If not execute the command TASKKILL /F /PID <ProcessId> from elevated prompt. So in my case,
C:\Windows\system32>netstat -ano | find "808"
TCP 0.0.0.0:808 0.0.0.0:0 LISTENING 5068
TCP [::]:808 [::]:0 LISTENING 5068
C:\Windows\system32>tasklist | find "5068"
OneApp.IGCC.WinService.ex 5068 Services 0 36,632 K
C:\Windows\system32>taskkill /F /PID 5068
SUCCESS: The process with PID 5068 has been terminated.
C:\Windows\system32>netstat -ano | find "808"
C:\Windows\system32>
Then Restart the Net.Tcp Port Sharing Service from services.msc
Even after rebooting the system OneApp.IGCC.WinService.exe will override the SMSvcHost.exe by listening to 808 port. So Disable running of Intel(R) Graphics Command Center Service (C:\Windows\System32\DriverStore\FileRepository\igcc_dch.inf_amd64_26b207b939eae50e) from services.msc
回答2:
It appears that you host the WCF service project in IIS and try to make it work over HTTP and Nettcp. In order to make it work over NetTcp protocol, we should enable certain Window features and NetTcp binding in the IIS site binding module. Also, we are supposed to configure a service endpoint with Nettcpbinding, which is not set up in your Webconfig file.
Please consider replacing the System.servicemodel section with the below configuration.
<system.serviceModel>
<services>
<service name="WcfService1.Service1">
<endpoint address="service1" binding="basicHttpBinding" contract="WcfService1.IService1" ></endpoint>
<endpoint address="service2" binding="netTcpBinding" contract="WcfService1.IService1"></endpoint>
<endpoint address="mex" binding="mexTcpBinding" contract="IMetadataExchange"></endpoint>
</service>
</services>
<bindings>
<basicHttpBinding>
<binding>
<security mode="Transport">
<transport clientCredentialType="None"></transport>
</security>
</binding>
</basicHttpBinding>
<netTcpBinding>
<binding>
<security mode="None"></security>
</binding>
</netTcpBinding>
</bindings>
<behaviors>
<serviceBehaviors>
<behavior>
<serviceMetadata httpGetEnabled="true" httpsGetEnabled="true"/>
<serviceDebug includeExceptionDetailInFaults="true"/>
</behavior>
</serviceBehaviors>
</behaviors>
<serviceHostingEnvironment aspNetCompatibilityEnabled="true"/>
</system.serviceModel>
In order to support Net.tcp protocol in IIS, please enable following windows feature.
Subsequently, Add Net.tcp support on the website.
Finally, add a site binding with net.tcp protocol. Note,808 is the default port for net.tcp protocol. Do not use the port number already used by another website.
Please refer to below link.
Could not find a base address that matches scheme net.tcp for the endpoint with binding NetTcpBinding. Base address schemes are [http]
Feel free to let me know if the problem still exists.
