Declaration
Property Value
| Type | Description |
|---|---|
| Boolean | true if XPO uses its internal mechanism to create new instances of persistent classes, and to set and retrieve object property values; false, to use the Reflection. |
Remarks
By default, XPO uses its internal mechanism to create new instances of persistent classes, and to set and retrieve object property values. This makes it possible to speed up the process of retrieving information about persistent classes. However, in some instances, this mechanism cannot be used (e.g. running in a medium trust hosted environment), and Reflection must be used instead. To do this, set the UseFastAccessors property to false (by default, it is set to true).
For example, to support a Medium Trust security policy, set the UseFastAccessors property to false and the XpoDefault.IdentityMapBehavior property to IdentityMapBehavior.Strong. All constructors/properties/fields of your persistent object must have the Public access modifier, so that XPO can access them without using Reflection.
