This sample shows how an app can provide files, a save location, and real-time file updates to other apps through the file picker by participating in the File Open Picker contract, File Save Picker contract, and Cached File Updater contract, respectively. This sample uses Windows.Storage.Pickers.Provider and Windows.Storage.Provider API.
The sample demonstrates these tasks:
-
Provide files by integrating with the File Open Picker contract
Uses the following API:
-
JavaScript: WebUIFileOpenPickerActivatedEventArgs class
C#/C++/VB: FileOpenPickerActivatedEventArgs class
method - FileOpenPickerUI class
-
-
Provide a save location by integrating with the File Save Picker contract
Uses the following API:
-
JavaScript: WebUIFileSavePickerActivatedEventArgs class
C#/C++/VB: FileSavePickerActivatedEventArgs class
method - FileSavePickerUI class
-
-
Provide real-time file updates by integrating with the Cached File Updater contract
Uses the following API:
-
JavaScript: WebUICachedFileUpdaterActivatedEventArgs class
C#/C++/VB: CachedFileUpdaterActivatedEventArgs class
method - CachedFileUpdaterUI class
- CachedFileUpdater class
Note This scenario requires the File picker sample.
