#if DEBUG
    private int _y;

Actual Behavior:

Note: It should place it in a compatible ifdef region if that's what sort of region it is in when you invoke the feature. for example:

    public C(int z)
    {
#if DEBUG
        _z = z;
#endif
    }

That said, we have almost no effort spent in the language service to try to do this kind of fine-grained analysis. About all we do is try to ensure that we don't accidentally move things around that overlap ifdefs, and that we do not try to remove parts of an ifdef.
