System.Net network tracing doesn't work in .net app

This is the only output is see in the log file. I made sure the TRACE is enabled  :

System.Net Information: 0 : [23592] Current OS installation type is 'Client'.

    ProcessId=25132

    DateTime=2022-03-30T17:49:56.1303174Z

System.Net Information: 0 : [17404] Current OS installation type is 'Client'.

    ProcessId=264

    DateTime=2022-03-30T17:50:37.3832981Z

This is the diagnostics section from my web.config file.
