This tool lists the lines of code that have been executed, the times have been hit and the time spent on each hit. The Profiler is updated with each debugger step and at the end of the execution.
The Profiler is accessible from the View menu or via a tab at the bottom of the IDE window. Use the "Enable Profiler" checkbox to enable or disable the profiler.
The Profiler does not run when an application is run using "Run Without Debugging".
