Tracing and Instrumenting Applications 

Tracing is a way for you to monitor the execution of your application while it is running. You can add tracing and debugging instrumentation to your .NET application when you develop it, and you can use that instrumentation both while you are developing the application and after you have deployed it. With the Trace and Debug classes, you can record information about errors and application execution to logs, text files, or other devices for later analysis.

Instrumenting your application by placing trace statements at strategic locations in your code is especially useful for distributed applications. With trace statements you can instrument an application not only to display information when things go wrong — you can also display information to monitor how well the application is performing.

The Trace and Debug classes are identical except that procedures and functions of the Trace class are compiled by default into release builds, but those of the Debug class are not. The following topics provide additional information on using instrumentation in your applications.
