The situation: I have the code like the following: interface IFoo { int Bar { set; } } class FooImpl : IFoo { public int Bar { get { return 0; } set { Console.WriteLine("Oops"); } } static void Main () { FooImpl fooImpl = new FooImpl (); IFoo foo = fooImpl; foo.Bar = 2; Console.WriteLine (fooImpl.Bar); } } When I invoke 'Safe Delete' on IFoo.Bar, not only the property declaration gets deleted, but also the 'foo.Bar' statement which is clearly incorrect.
