Answer 1

The "do nothing" doesn't really work for ?

if by // Return Nothing you actually mean return null then write

return Source;

if you mean, ignore the codepath then write

 if ( Source != null )
            {
                return Source;
            }
// source is null so continue on.

And for the last

 if ( Source != value )
            { Source = value;
                RaisePropertyChanged ( "Source" );
            }

// nothing done.
