Difference between Convert.ToString() and ToString() method

Convert.ToString() handles null values and not throws ObjectReferenceNullException whereas ToString() does not handles the null value and throws the null exception error message.

In MVC - Model View Controller , now controller is the view model. View-Model is responsible for exposing the data objects from the Model in such a way that view objects are easily managed and consumed. Why should I use MVVM? 1.
