TEntityModelOptions.Usage

Specifies when the model is used.

Unit

Syntax

Remarks

The property specifies when the XML model is used.

If the umDesignTime is specified in TEntityModelOptions.Usage, then the meta model becomes accessible at design-time, so properties such as TEntityConnection.DefaultModelName, TEntityContext.ModelName and TEntityTable.TypeName can be configured.

If the umRunTime is specified in TEntityModelOptions.Usage, then the meta model can be used at run-time. For mapping meta model to the entity classes, the special [XmlMapped] class attribute is used. See the XML-mapped entities article for details.
