Debug.Write and Trace.Write

The basic difference between the Debug and Trace classes is that Debug should only be used for debug builds but Trace can be used for both debug and release builds.

To reflect this, VS (by default) defines both the DEBUG and TRACE symbols when debugging but only the TRACE symbol in a release build.

To quote what it says in MSDN about the Trace class:

"You can use the properties and methods in the Trace class to instrument release builds. Instrumentation allows you to monitor the health of your application running in real-life settings. Tracing helps you isolate problems and fix them without disturbing a running system."
