Sample Code

A sample of the completed code for each exercise is available in the TechNet Gallery.  There is a separate sample for each exercise that includes the management pack completed at the end of that exercise and each preceding exercise.  This strategy allows you to work through each exercise in order and then compare your results.  For VSAE, this also includes the Visual Studio solution.
