Code Context
In Visual Studio debugging, a code context:
Provides an abstraction of a position in code as known to the debug engine (DE). For most run-time architectures today, a code context can be thought of as an address in a program's instruction stream. For nontraditional languages, where code may not be represented by instructions, a code context may be represented by some other means.
Describes the current position in the execution stream of the program being debugged.
Exists only when a program has stopped at a breakpoint.
Has an associated document context.
Is implemented by an IDebugCodeContext2 interface.
