T:Windows.ApplicationModel.AppInstance |
winrt class |
Represents an instance of an app.
The system maintains a store of app instances. Apps can use this for redirection of an app when it attempts to activate.
When an app process is created in the Main method of the app, it can choose to continue to activate the current instance, or to redirect the activation to an existing instance.
The shell can provide a preferred instance for redirection. The app is encouraged to redirect to that instance. The choice of whether to redirect remains with the app.
The AppInstance class is intended to be used in the Main method of the app. If this class is used later, the property values may be null, and the methods may fail.
Before any instances can be returned, they must be registered with FindOrRegisterInstanceForKey.
This class can only be used from an app that has opted in to multi-instancing. Specify the SupportsMultipleInstances attribute on the Application element in the package manifest for the app.
