Description
The user mode WFPSampler.exe does not output any logs to the console.
After checking the code, it seems this PR https://github.com/microsoft/Windows-driver-samples/pull/1108 simply removed the final wprintf calls in https://github.com/microsoft/Windows-driver-samples/blob/main/network/trans/WFPSampler/lib/HelperFunctions_Log.cpp for some reason ?
