XafApplication.ObjectSpaceProviders Property

Gets a list of Object Space Providers used by XafApplication.

Namespace: DevExpress.ExpressApp

Assembly: DevExpress.ExpressApp.v21.1.dll


public IList<IObjectSpaceProvider> ObjectSpaceProviders { get; }

Property Value

Type Description

An IList<IObjectSpaceProvider> list of Object Space Providers.


To specify a custom Object Space Providers list, override the XafApplication.CreateDefaultObjectSpaceProviders method and pass the list to the CreateCustomObjectSpaceProviderEventArgs.ObjectSpaceProviders property. An example is available in the How to: Use Both Entity Framework and XPO in a Single Application topic.


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.
