This PR uses the existing EventSource implementation to enable event tracing in SNI.dll. Events must be captured using a tool like Xperf.
Tracing can be enabled by sending a command to SqlClientEventSource:
// Enables trace events:EventSource.SendCommand(eventSource, (EventCommand)8192, null);// Enables flow events:EventSource.SendCommand(eventSource, (EventCommand)16384, null);// Enables both trace and flow events:EventSource.SendCommand(eventSource, (EventCommand)(8192 | 16384), null);
