What is Tracing and what are the adavantages of using tracing to log exceptions? 

Tracing is a technique for recording events, such as exceptions, in an application. There have always been ways to record errors in an application - usually by opening a file and writing error messages to it. But tracing offers the following significant advantages:
 

Standardization:Building tracing into the .NET Framework ensures that programming techniques are the same across all the applications you develop with the .NET Framework.
 

Built-in Web support:ASP.NET extends the .NET Framework tools by including information related to the performance and behavior of Web requests.
 

Configuration:You can turn tracing on and off using settings in your application’s configuration file. You don’t have to recompile your application to enable or disable tracing.

Performance:While disabled, tracing statements do not affect application performance.
