What happens in C# if an object A that has a field referring to

void main() {
auto a = new C;
auto b = new C;
a.another = b;
b.another = a;
}
What happens then? Will the GC nullify references to destroyed
objects, or will it put them in a zombie state?
Thanks,

In this case the a and b objects will be collected by GC and
memory freed.
It's a one of most popular questions about .NET GC. Maybe
something was changed in .NET >= 4.5.
I have another question: there available a good example of
idiomatic destructor usage in the D?
Something without calling a rt_ hooks on destroy?
