Enum types Support

•    Enumeration types are used to define a set of named constants that may be assigned to a numeric

value.

•    By defaultthe underlying type of each element in the enum is int. But it can be specified another

numeric type by using a colon. Example:enum Months : byte {Jan, Feb, Mar, Apr, May, Jun, Jul,

Aug, Sep, Oct, Nov, Dec};

•    When a value is not specified in the defined list, the values are automatically incremented by 1. In

the previous exampleMonths. Jan has a default value of 0.

In order to use enum types inside an Entity Framework defined class it should follow the next steps:

In Visual Studio 2012 Using Database First approach

•    Create a new project (make surę .NET framework is target in the New Project dialog.),

•    Add a new Entity Model

•    Select the Existing Database option

•    Select the tables to be imported in the model

•    In order to create an Enum Type an integer column should exists inside of a table.
