Package with App Service
App Service
Background Task
var conn = new AppServiceConnection();
conn.AppServiceName = “FooAppService”;
conn.PackageFamilyName = “12Me.MyApp“;
var status = await conn.OpenAsync();

28. 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

29. 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

30. 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
