How is interpreted an enum type with EF Code First

问题:

Here is a model:

Public class Person {     [Key]     Public int PersonId { get; set: }     Public int Age { get; set; }     Public ColorEnum FavoriteColor { get; set; } }  Public Enum ColorEnum {     Red = 1,     Green = 2,     Blue = 3 } 

Is it possible for Entity Framework Code First to use the Person model to generate the corresponding table? What about the ColorEnum type?

Thanks

EF 4.3 doesn't support Enums. But is has been announced that Enum support is coming with EF 5, which is due out alongside .NET 4.5. To handle enums with Code-First currently you'll do something like the following:

Public class Person {     [Key]     Public int PersonId { get; set: }     Public int Age { get; set; }      public int FavoriteColorValue{ get; set;}     [NotMapped]     Public ColorEnum FavoriteColor      {          get{ return (ColorEnum)FavoriteColorValue; }          set{ FavoriteColorValue = (int)value; }      } }  Public Enum ColorEnum {     Red = 1,     Green = 2,     Blue = 3 }
