Common.logging

Engine now support more flexible way to debug messages and exceptions by using Common.logging library which support logging into most popular logging "framework" like log4net, Enterprise Library Logging, NLog.

All included examples have sample app.config to show you how to implement this kind of logging into your application (samples use NLog implementation).

@ligu: Old debuging functions also work as before but only if you have explecit define DebugFileLogPath in your FIX config.

If we need any test on this please tell me what kind...
