Debugger

Tips and Tricks

in Visual Studio 2013Slide3

“Everyone knows that

debugging is twice as hard

as writing a program in the first place. So if you're as clever as you can be when you write it, how will you ever debug it?”

Brian Kernighan, Computer Scientist

“There has never been an unexpectedly short debugging period in the history of computers.”

Steven Levy, Computer Journalist

“As soon as we started programming, we found to our surprise that it wasn't as easy to get programs right as we had thought. Debugging had to be discovered. I can remember the exact instant when I realized that a large part of my life from then on was going to be spent in finding mistakes in my own programs.”

Sir Maurice Wilkes

JMC tells the debugger to treat certain code as not yoursCode that was determined to be not your code

is hidden from Call Stack display (though it can be easily toggled)

Is omitted from stepping (and exceptions thrown/caught ) for .NET and JavaScript

Not your code is code that is.NET Optimized or has no symbols availableJavaScript Defined in the .json fileC++ Defined in .natjmc filesJust My Code – now for C++ & JavaScript
