EF6 - Annotation to allow empty string but not allow null

Question

In EF6, is there a annotation that will allow empty string but not allow null?

I've tried [Required]. But this annotation does not allow empty string or null.

[Required]
[MaxLength(80)]
public string ShortDescription { get; set; }

Answer 1

Looks like I just need to add the (AllowEmptyStrings = true) option to the [Required] annotation.

[Required(AllowEmptyStrings = true)]
[MaxLength(80)]
public string ShortDescription { get; set; }
