A resolved version of StackFrame. Contains source code locations and code
offsets, if the resolver was able to locate symbols for this frame.
Otherwise, the additional attributes are empty.
Contains information from the memorydump, especially the frame’s instruction
pointer. Also references an optional CodeModule that contains the
instruction of this stack frame.
Indicates how well the instruction pointer derived during
stack walking is trusted. Since the stack walker can resort to
stack scanning, it can wind up with dubious frames.
