.NET 4.8 WCF application Server 2022 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?

Thank you,

Kevin Young

    If the "Net.Tcp Listener Adapter" service is not present, then open an elevated Command Prompt

    Run the following command:

    dism /online /enable-feature /featurename:WCF-TCP-Activation45

    Hello,

    To resolve the issue, you may try these:

    Check WAS Installation and Status:

    Ensure that the Windows Process Activation Service (WAS) is installed and running on your Windows Server 2022.

    Enable WCF Non-HTTP Activation:

    Open Command Prompt (as Administrator).

    Run the following DISM command to enable WCF non-HTTP activation:

    dism /online /enable-feature /featurename:WCF-NonHTTP-Activation

    Note: If a specific version-based feature name is required (though unlikely for standard WCF TCP activation), replace WCF-NonHTTP-Activation accordingly.

    Additionally, as .NET Framework 4.8 is typically compatible with multiple versions of Windows Server, ensuring your server configuration and updates are current is also important.
