Tinyint(byte),SmallInt(Int16) not compatible with Enum in EF5

Question

Using Database first design and having tinyint (or smallint) column:

[MyEnumColumn] [tinyint] NOT NULL

I mapped this column to Enum Type in EDM

Answer 1

You need to specify both in the Model and in the Enumerator that you are using tinyInt and Byte .

in Enumerator definition public enum MyEnumType : byte { One, Two, Three, All }

then in the Model class file

 [Column(TypeName = "tinyint")]
    public MyEnumType? MyEnum { get; set; }
