Logging Information from the Application

This section contains topics that cover how to log information from your application using the My.Application.Log or My.Log object, and how to extend the application's logging capabilities.

The Log object provides methods for writing information to the application's log listeners, and the Log object's advanced TraceSource property provides detailed configuration information. The Log object is configured by the application's configuration file.

The My.Log object is available only for ASP.NET applications. For client applications, use My.Application.Log. For more information, see My.Application.Log Object and My.Log Object.
