Web API Sample

Web Api framework is Http based and can be accessed from broad range of clients like Browser, Mobile App etc.

REST uses some common HTTP methods to insert/delete/update/retrieve information. These Http methods are:
1.GET - Requests a specific representation of a resource
2.PUT - Creates or updates a resource with the supplied representation
3.DELETE - Deletes the specified resource
4.POST - Submits data to be processed by the identified resource

Data Type supported:

• XML
• JSON
• ATOM

This sample application demonstrates how to use Web API framework to return all posts from your blog in Json format.
