9. ADAL – Main Token Acquisition Pattern
Abstracts away most protocol considerations
Handles tokens persistence & refresh automatically
AuthenticationContext ctx=
new AuthenticationContext("
AuthenticationResult rez = await ctx.AcquireTokenAsync(
"
"5fc4a5a2-78d5-4d94-b890-a6e6b ");

10. ADAL .NET Current supported version: V3.x Desktop
Default cache in-memory
Extra flows for public clients only:
Windows integrated authentication
Direct use of username & password
Windows Store & WinRT
Persistent per-app cache
Windows Runtime Components
Works with C#, WinJS, C++
Full Xamarin Support

Adding offline sync to an app is usually hard. With App Service, it’s easy.

15. Why use mobile data sync?
Improve app responsiveness by caching server data locally on the device.
Make apps resilient against intermittent network connectivity.
Allow end-users to create and modify data even when there is no network access.
Detect and handle conflicts when the same record is modified by more than one client.

Mobile file sync architecture
Mobile App backend reads from SQL and writes through to CRM
Mobile client SDK syncs SQLite db with Azure Mobile backend
Note: Client apps do not communicate directly with backend data source

Push-to-sync
Client devices sync infrequently or only by manual user action
Saves battery
Saves data usage
Reduces server load
Client registers queries with server
Server sends a push notification when client needs new data
When client receives push notification, it syncs that query.

25. Server side Client query is mapped to a Notification Hub tag
Microsoft Ignite 2016
5/25/ :22 PM
Server side
Client query is mapped to a Notification Hub tag
Server sends push notification when query result has changed
If data changes infrequently, server can send the push when data changes
Else, scheduled job on server checks for changes to registered queries.

26. Intro to Azure Notification Hubs
Microsoft Ignite 2016
5/25/ :22 PM
Intro to Azure Notification Hubs
Client app retrieves handle from Platform Notification Service (PNS), sends to App Service backend
Backend service registers with Notification Hub, using tags to represent a query
App back-end sends notification to logical user or group of users using Notification Hub tags
Notification Hub delivers notifications to matching devices via PNS
Notification Hub manages scale
Notification Hub maps tags to device handles

27. Managing Scale More clients means more load on data source
Design queries so that server can use indexed columns to determine query change
Minimize use of client-specific queries
Reduces the number of “check changes” queries the server runs
Consider sharding the database
Consider using a secondary DB for change queries
