Notes GetLogger injected ILogger - NLog/NLog.Extensions.Logging GitHub Wiki

Some important notes:

• The configuration in LogManager.Configuration will be used for LogManager.GetLogger/LogManager.GetCurrentClassLogger and injected ILogger<T>
• When using "Microsoft.Extensions.DependencyInjection", the injected ILogger<T> is preferred over LogManager.GetLogger/LogManager.GetCurrentClassLogger
• When using the injected ILogger<T>, you need to enable the integration with builder.AddNLog (that's in your code example).
