How your Metro style apps can participate
You’ll leave with examples of how to
Participate in the file type / protocol association system
Participate in the AutoPlay system

3. 5 things you need to know User Experience Registration Activation

10. Registration via manifest
Declare your supported file types and/or protocols
Add AutoPlay Content or Device declarations to respond to device events
Remember: New scenarios (NFC) can take advantage of these registrations

12. Responding to activation events
File access is through the trust broker
Persist StorageFile items that you need to access across sessions
Responding to activation events from AutoPlay has been simplified for Metro style apps
AutoPlay will now call your app with your verb and the root folder of the device content

13. Receiving a StorageFile Item
// Receive activation.
function onActivatedHandler(eventArgs) {
if (eventArgs.kind == Windows.ApplicationModel.Activation.ActivationKind.file) { …
sdkSample.displayStatus("File activation received. The number of files received is " + eventArgs.files.size + ". The first received file is " + eventArgs.files[0].name + ".");

14. Persisting access to a StorageFile item
StorageApplicationPermissions.mostRecentlyUsedList.add
// From FileAccess SDK sample
function scenario5AddToMRU() {
//Adding sample.txt in the MRU list
if(sampleFile != null) {
mruToken = Windows.Storage.AccessCache.StorageApplicationPermissions.mostRecentlyUsedList.add(sampleFile, sampleFile.fileName);
id("scenario5Output").innerHTML = '<p>The file <b>sample.txt</b> was added into MRU list and a token was stored.</p>'; }

Windows.System.Launcher.launchDefaultProgramForFile(file);
Basic usage – launch a protocol
Windows.System.Launcher.launchDefaultProgram(uri);
Force OpenWith to appear (for use in a secondary action)

20. Guidelines for existing apps
You don’t need to check to see if your app is the default
You don’t need to set your app as the default
You don’t need to manage defaults for file types and protocols from within your app
You could integrate with the control panel instead

How to respond to activation in your apps
How to launch other files and protocols
