When unhandled exceptions are encountered in VStudio usually the debugger highlights the line YELLOW as the line that threw the exception.
However sometimes
The line is highlighted yellow if that is the line that directly threw the exception (typically a throw
statement).
It's green if the line is a call to a different function that threw the exception (typically a call to a .Net function that threw an exception).
The yellow line is the line where the exception is really thrown.
The green line indicates a line that is indirectly affected.
I think the screenshot makes it clear. Note that I had to use the "Callstack" window and switch to the Main()
method in order to achieve this effect.
