The document discusses extending enterprise applications to mobile users, outlining mobile solution design, API exposure, and various architectures, including the use of Xamarin for cross-platform development. It highlights the importance of mobile-friendly web APIs, data synchronization, and offline access while also mentioning Microsoft services like Azure Active Directory. Furthermore, it provides references to additional resources and case studies related to mobile app development using Xamarin and Microsoft technologies.

5. Exposing Mobile Friendly Web APIs

6. WCF vs. ASP.NET Web API
WCF ASP.NET Web API
Multiple transport protocols (HTTP, TCP, UDP, and
custom transports)
HTTP only. First-class programming model for
HTTP
Multiple encodings (Text, MTOM, and Binary) of
the same message
Wide variety of media types including XML, JSON
etc.
WS-* standards like Reliable Messaging,
Transactions, Message Security
Basic protocol and formats such as HTTP,
WebSockets, SSL, JQuery, JSON, and XML
Request-Reply, One Way, and Duplex message
exchange patterns
HTTP is request/response but additional patterns
can be supported through SignalR and
WebSockets
WCF SOAP services can be described in WSDL,
generate client proxies
Many ways to describe: Auto-generated HTML
help page describing snippets to structured
metadata for OData integrated APIs
Ships with the .NET framework
Ships with .NET framework, open-source,
available out-of-band

13. Xamarin’s Unique Approach
Shared C# codebase • 100% native API access • High performance
Included in Visual Studio (free) • Open Source
iOS C# UI Windows C# UIAndroid C# UI
Shared C# Logic

14. Xamarin + Xamarin.Forms
With Xamarin.Forms:
more code-sharing, native controls
“Classic” Xamarin approach
Shared UI Code

Reusing Code for Xamarin.Forms Projects

16. Sample Architecture: Finaeos 1to1Core

17. ▪ Sometimes you don’t have a choice
Reusing Existing Web-based Login

18. ▪ It works, but is there a better way?

Authentication & Authorization

20. Our vision
Identify 30K
potentially
compromised
users per day
Every day the identity ML
system processes
10TB of data
Deflect 1.5M
attacks per day in the
consumer space
Reaches the audience you want
Has great fundamentals
Works great with your solution
An ideal identity system…

Production-ready MSAL previews

22. Demo:
Microsoft Authentication Library (MSAL)

23. Azure Active Directory B2C
Reach any user, on any platform
Scale to 100s of millions of user accounts
Run on the same secure, highly available
infrastructure that powers O365 authentications
Select from a set of built-in, self-service identity
experiences
Customize each pixel. It’s your brand, your HTML
and CSS

24. Microsoft Graph
Single API that proxies multiple Microsoft services
Allows for easy traversal of objects and relationships
Eliminates the need to discovery endpoints
Only one OAuth access token needed
For both personal and work and school accounts
Exposing User data, Group data and Organizational data

Data Synchronization & Offline Access

26. Create a Mobile Service
MobileService = new MobileServiceClient(
"https://myapp.azurewebsites.net");

27. Create Tables
IMobileServiceSyncTable<Store> table;
public async Task Init()
{
const string path = "syncstore.db";
var db = new MobileServiceSQLiteStore(path);
db.DefineTable<Store>();
}
var handler = new MobileServiceSyncHandler();
await MobileService.SyncContext.InitializeAsync(db, h);
table = MobileService.GetSyncTable<Store>();

28. Get and Modify Data
public async Task<IEnumerable<Store>> GetStoresAsync()
{
await table.PullAsync("allStores", table.CreateQuery());
return await table.ToEnumerableAsync();
}
public async Task<Store> AddStoreAsync (Store store)
{
await table.InsertAsync (store);
await table.PullAsync("allStores", table.CreateQuery());
await MobileService.SyncContext.PushAsync();
return store;
}
