Property Value

Type	Description
IList<IObjectSpaceProvider>	An IList<IObjectSpaceProvider> list of Object Space Providers.

Remarks

XAF uses an Object Space Provider to create Object Spaces. The following Object Space Provider types are supplied with XAF:

Space Provider	Object Space
XPObjectSpaceProvider	XPObjectSpace
EFCoreObjectSpaceProvider<TDbContext>	EFCoreObjectSpace
SecuredObjectSpaceProvider	SecuredXPObjectSpace
SecuredEFCoreObjectSpaceProvider<TDbContext>	SecuredEFCoreObjectSpace
NonPersistentObjectSpaceProvider	NonPersistentObjectSpace

XAF applications configure Object Space Providers through the Application Builder’s ObjectSpaceProviders property. When you use the Template Kit to create an application, it adds the Object Space Providers to your application based on the specified presets.

Refer to the following topic to learn how to add custom Object Space Providers to your application: Custom Object Space Provider.

Note

When multiple Object Space Providers are registered in the XafApplication.ObjectSpaceProviders property, the ModuleUpdater.UpdateDatabaseAfterUpdateSchema method is executed multiple times, once for each registered Provider. In this method, before accessing an object of a particular type, check if the current Object Space supports this type using the IObjectSpace.CanInstantiate method.
