IT Professional Curricula Software Development Solution Area Defensive Programming Defensive Programming in C#

Defensive Programming is a methodology for writing code that is not prone to present or future errors potentially caused by unexpected user inputs/actions. In this course you will explore the fundamentals of defensive programming including inspections, testing, input validation, error handling, planning, methods, variables, assertions, and iterative design.
