//! Demonstrates how to generate and use an ETW wrapper.

//! This example does not build or register the message and metadata tables, so the capture file
//! only indicates that the events were emitted.

// By default each provider generates a PascalCaseSymbolLogger struct
// Here ProviderWidgetserviceLogger is overridden with the name WidgetLogger
