The document discusses ASP.NET Web API, a framework for building RESTful web services on the .NET platform. It can be used to build HTTP services that work with a variety of clients, including browsers and mobile devices. The document also covers RESTful principles and how ASP.NET Web API uses routing, controllers, and formatting to expose data from Windows applications via a web API. It concludes with resources for learning more about ASP.NET Web API and building services for Windows 8 and Windows Phone applications.

2. Agenda
 What and Why
 RESTFul Web API
 ASP.NET 4 Web API
 Windows 8 and Windows Phone Data Access Strategy

3. What and Why
 Is a framework that makes it
easy to build HTTP services
that reach a broad range of
clients, including browsers and
mobile devices.
 Is a ideal platform for building
RESTful applications on the
.NET Framework.

4. RESTFul Web API
 Representational State
Transfer (REST) is a style of
software architecture
for distributed systems
 Ideated by Roy Fielding
 No standard
 Public application API

5. ASP.NET Web API
 Part of ASP.NET MVC 4
 Build on top of ASP.NET
Web Stack
 Routing, Controller-based,
Fine-grind control over
HTTP, Model Binder,
Formatter (JSON and XML),
OData

7. Win8 and WP Data Access Strategy
 Data stay on server-side
 Exposed to clients by Web
API
