Thread: Edit and continue feature

Hello everyone,


Mentioned in the book -- "CLR via C#", page 15, chapter 1 "The CLR's Execution Model",

--------------------
the C# compiler will emit NOP (no-operation) instructions into the code. The NOP instructions are emitted to enable edit-and-continue feature while debugging.
--------------------

What means "edit-and-continue" feature? Why emitting NOP instructions will facilitate this feature?


thanks in advance,
George
