EdmScalarPropertyAttribute Class

Attribute that indicates that the property represents a scalar property.

Namespace:  System.Data.Objects.DataClasses
Assembly:  System.Data.Entity (in System.Data.Entity.dll)

public sealed class EdmScalarPropertyAttribute : EdmPropertyAttribute

The IsNullable and EntityKeyProperty properties cannot both be true because key members cannot be null.

The EdmScalarPropertyAttribute links a scalar property on a data class to a property of an entity type or complex type that is defined in the conceptual model.

This attribute is applied to properties that return scalar types.

When using custom data classes with an Entity Data Model (EDM), you must manually apply attributes. For more information, see Object-Entity Mapping Attributes (Entity Framework).


Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
