Remarks

Windows 10 The LoggingActivity class has been extended in the following ways:+ Now implements ILoggingTarget which provides activity start and stop methods that provide control over the format and contents of the Start and Stop events.

  • Now implements methods to log events. Events are automatically tagged with the LoggingActivity's GUID.
  • Activities can be nested. Every LoggingActivity object is attached to a LoggingChannel object. All events created by the LoggingActivity object are written through the attached LoggingChannel object.
