ASP.NET Web API
Windows Azure
Custom Software Development MobileMiddleware
From WCF to ASP.NET Web API• First apear as WCF Web API• HTTP related• WCF -wider that HTTP (TCP, Named Pipe,
WinService, etc)• ASP.NET is closer technology• Can be treated as part of .NET vNext
Windows Azure
Custom Software Development MobileMiddleware
ASP.NET Web API
• Modern HTTP programming model• HTTP related• Full support for ASP.NET Routing• Content negotiation and custom formatters• Model binding and validation• Filters• Query composition• Code-based configuration• Self host
Windows Azure

Demo: Simple ASP.NET Web API App
Integration in MVC 4
Invoke operation
from browser
Add opeartion with params
GET, POST, PUT, DELETE

Web Protocols
• SOAP• REST• SOAP Contract vs. Contract based on
document Three (REST)• Formatting (HTML, OData, etc.)

Routing
• Web API uses HTTP methods• MVC-style Routing is still avaliable• Controller handles HTTP requests• Set routing to
HttpSelfHostConfiguration

Routing
HTTP Method URI Path Action Parameter
GET api/products GetAllProducts (none)
GET api/products/4 GetProductById 4

HttpClient
• Modern HttpCLient for .NET• NuGet packages– System.Net.System– System.Net.Http.Formatting– System.Json
• Hady when using in JavaScript code

Recap
• New way of building REST based web application
• Easy of using• Built on top of APS.NET MVC• Routing convention• HTTP Standard method GET, POST, PUT,
DELETE• Still support MVC routing methods• Different Formatters: XML, JSON, Custom• Different Filters
