You are designing an ASP.NET Web application. You have the following requirements:
– The application must be usable in partially connected scenarios.
– Data that is entered into the application offline must be synchronized with the server the next time the application is online.
You need to design the application to meet the requirements.
What should you use?
A.
jQuery
B.
ASP.NET AJAX
C.
WCF Data Services
D.
Microsoft Silverlight
Explanation:
WCF Data Service: Service layer exposes raw data sources
http://jack.ukleja.com/wcf-data-services-vs-wcf-ria-services/The Silverlight application can also run offline but only if your code works in such a way that this is allowed. By that I mean you can work with IsolatedStorage to save some information local and use network detection to check for a network. If your application relies on services or files that are online you can disable working in offline mode (but still enable out of browser).
