// Sample 3: DebugLog
//
// sometimes is may be necessary to peek under the hood of SteamKit2
// to debug or diagnose some issues
//
// to help with this, SK2 includes a component named the DebugLog
//
// internal SK2 components will ocassionally make use of the DebugLog
// to share diagnostic information
//
// in order to use the DebugLog, a listener must first be registered with it
//
// by default, SK2 does not install any listeners, user code must install one
//
// additionally, the DebugLog is disabled by default in release builds
// but it may be enabled with the DebugLog.Enabled member
//
// you'll note that while this sample project is relatively similar to
// Sample 1, the console output becomes very verbose
//

// install our debug listeners for this example

// install an instance of our custom listener
// see the bottom of this file for how it is defined.
DebugLog.AddListener( new MyListener() );

// install a listener as an anonymous method
// this call is commented as it would be redundant to install a second listener that also displays messages to the console
// DebugLog.AddListener( ( category, msg ) => Console.WriteLine( "AnonymousMethod - {0}: {1}", category, msg ) );

// Enable DebugLog in release builds
