Even if I set log level to None, access.log continues growing with information of each connection.

I understand that the logs are written by XRayCore.dll, which is not under your control. But your wrapper provides fully qualified log file names to the library and a log type. Could you provide log.LogType_None as AccessLogType for log level 'None'? Or, if it does not work, provide just "nul:" as AccessLogPath? Sorry, I can't check it myself right now.

My current workaround is \\.\NUL\null as the log path, but it is not convenient for most of users.
