C# Development for Beginners #12: Debugging - Finding and Fixing Your Code Problems
Bugs are inevitable, but finding them doesn't have to be painful! Learn essential debugging techniques that will save you hours of frustration.
What you'll learn:
• Reading error messages (they're trying to help you!)
• Common C# error messages decoded
• Console.WriteLine debugging - the classic approach
• Strategic placement of debug output
• Setting breakpoints in VS Code
• Step through, step over, step into explained
• Watch windows and variable inspection
• Conditional breakpoints for tricky bugs
• The systematic bug-finding process
• Why your breakpoint might not be hitting
Key debugging wisdom:
• Error messages point you to the problem
• Start with the simplest debugging technique
• Breakpoints let you watch your code execute
• Debugging is how you truly learn what your code does
Common mistakes we'll fix:
• NullReferenceException (the #1 C# error)
• "Does not exist in the current context"
• Index out of bounds
• Build vs runtime errors
