Because you are referencing "TNS" which is the Oracle service that accepts incoming requests to an Oracle database instance.
What you really want is the TCP Listener Adapter.
Open control panel and verify that you have the feature turned on.

Then open a Powershell prompt and run this command.
Get-Service | Where-Object {($_.Name -like '*tcp*') -or ($_.DisplayName -like '*tcp*')}
Verify that NetTcpActivator is one of the services that is listed.
