Question

We have a .NET 4.8 WCF application that we are having trouble getting to run on Windows Server 2022.  We have traced the problem to the "Net.Tcp Listener Adapter" service not being present. We have enabled all IIS Roles and all .NET Framework Features, but the service doesn't seem to be there.  What Role and/or Feature needs to be installed for this service to be present and running?

You can also install the necessary features using PowerShell:
