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 the Windows.Storage.Pickers.Provider and Windows.Storage.Provider APIs.
Note: This sample is part of a large collection of UWP feature samples. If you are unfamiliar with Git and GitHub, you can download the entire collection as a ZIP file, but be sure to unzip everything to access shared dependencies. For more info on working with the ZIP file, the samples collection, and GitHub, see Get the UWP samples from GitHub. For more samples, see the Samples portal on the Windows Dev Center.
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](http://msdn.microsoft.com/library/windows/apps/hh7004400 class method
- CachedFileUpdaterUI class
- CachedFileUpdater class

- If you download the samples ZIP, be sure to unzip the entire archive, not just the folder with the sample you want to build.
- Start Microsoft Visual Studio 2017 and select File > Open > Project/Solution.
- Starting in the folder where you unzipped the samples, go to the Samples subfolder, then the subfolder for this specific sample, then the subfolder for your preferred language (C++, C#, or JavaScript). Double-click the Visual Studio Solution (.sln) file.
- Press Ctrl+Shift+B, or select Build > Build Solution.
The next steps depend on whether you just want to deploy the sample or you want to both deploy and run it.
- Select Build > Deploy Solution.
- To debug the sample and then run it, press F5 or select Debug > Start Debugging. To run the sample without debugging, press Ctrl+F5 or selectDebug > Start Without Debugging.
