   * Note: enum support 
   * Although we use EF5 enums are not supported as we target .NET 4.0.
   * Therefore we use the following workaround:
   * Just create an int property on your class to represent the int value of the enum. 
   * That's the property that EF should map, then have a "mini wrapper" property to allow you to use the enum
   * For example see class PaymentInformation
