RSRP-288208: Extract to assignment statement breaks code

class Base { }
class Derived : Base {
  public int Prop { get; set; }
}

Base b = new Derived() {
  Prop = 2
};

On "new Derived", executing the context action "Extract Prop to assignment statement" turns the code into :

Base b = new Derived();
b.Prop = 2;

There is no Prop member on Base so compilation fails. Please either disable the context action or add a cast to Derived.
