Kellerman .NET Logger - Version 1.22 Kellerman Logger is an easy to use, high performance logging framework for .NET 2.0 with the ability to log to multiple destinations. Kellerman Logger is faster and easier to use than Log4Net. The logger's ability to log messages with a single line of code makes Console.Writeline and Response.Write obsolete. Why use Kellerman Logger? The problem with all logging frameworks currently available (both open source and commercial) is that they sacrifice usability for extensibility. Modifying long configuration files is the only way to get them to work. Sure, there are examples for the configuration files, but it's not exactly one line of code. Kellerman Logger takes a different approach; to match the ease of use of Console.Writeline and Response.Write and add features to facilitate defect tracking and back end development. How many times have you written Response.Write(ex.Message)? Instead with Kellerman Logger write Log.LogException(ex); and the logger will write out not only the error message but all the properties of the exception and any inner exceptions.
