What is this C# syntax called?

WeirdSyntax.cs

namespace Trine.CLI
{
    class Program
    {
        static void Main()
        {
            new Crash
            {
                Inner = {Name = "what"}
            };
        }
    }


    public class InnerType {
        public string Name { get; set; }
    }

    public class Crash
    {
        public InnerType Inner { get; set; }
    }

}

wierd? its called "object initializer"

namespace Trine.CLI
{
    class Program
    {
        static void Main(string[] args)
        {
            new Crash
            {
                InnerNew_Property = { Name = "what" }
            };
        }
    }
  public class InnerType
    {
        public string Name { get; set; }
    }

    public class Crash
    {

        private InnerType InnerNew_Field = new InnerType();

        public InnerType InnerNew_Property
        {
            get
            {
                return InnerNew_Field;
            }

            set
            {
                InnerNew_Field = value;
            }
        }
    }
}
