No - its value is unassigned, at least as far as the C# language is
concerned. An implementation could choose to clear the memory, but it
doesn't have to, as far as I'm aware. You won't be able to "see" the
contents of the memory until it's been definitely assigned anyway.

Actually a 'debuggable' builds (in most cases that build from
'DEBUG'-Configuration), its preset with null. But only, so that the debugger
has something to show, if it's stop before the assignment and the programm
has a specific behavior if the execution point is changed through the
debugger.

Conceptually local variables don't have initial values (if they aren't
initialized explicitly.)
