Shared App Folder

http://windows.Microsoft.com

1. Set breakpoints in app service code

2. Check ‘Do not launch but debug my code when it starts’ in project properties

3. Launch app service foreground app in debugger – nothing happens!

4. Run client app to connect to app service

5. Debugger attaches and breaks on your breakpoint

Debugging an App Service

http://windows.Microsoft.com

Service is activated on-demand

Client may terminate service by disposing its AppServiceConnection

If the invoking app is suspended, app services sponsored by the app will be terminated

Insufficient resources may cause launch failure or service termination

App Service Lifetime

http://windows.Microsoft.com

Wrap your custom scheme or app service in an SDK

Use NuGet to distribute SDK

Use REST-style versioning. For breaking changes, expose a new endpoint

Best Practices

Windows.System.LauncherLink to a specific app

Pass arbitrary data

Send files

Launch apps for results

Windows.ApplicationModel.AppServicesProvide services to other apps

Consume services provided by other apps
