Can a conforming C# compiler optimize away a local (but unused) variable if it is the only strong reference to an object?

or, in other words: Can an object referenced by a local variable be reclaimed before the variable goes out of scope (eg. because the variable is assigned, but then not used again), or is that object guaranteed to be ineligible for garbage collection until the variable goes out of scope?
