C#12 short way to write MVVM command getter using lambda expression

This is a very simple way to shorten the typing procedure for MVVM ICommand getter (introduced with C#6.0). Lambda expressions are here shown for ICommand getter but it can be used with any other property. If you want need an example write a comment to this post and we will provide an example for you

Long (old) way

        public ICommand ShareValueCommand
        {
            get
            {
                return new RelayCommand(ShareValueMethod);
            }
        }

Short (new) way

        public ICommand ShareValueCommand => new RelayCommand(ShareValueMethod);
