title: What do I use to replace ToNullSafeString() removed from AutoMapper 3?
body: <p>I have code using AutoMapper 3.2.1.0 that uses the method ToNullSafeString().
  I upgraded the NUGet package to 4.1.1.0, and I can no longer find the method in their package.Does anyone know the recommended approach to replacing the function? Is there a new construct that is functionally equivalent? If so, I cannot figure what it is. Nor can I find any mention of why it was removed.</p>
