ASP.NET provides a handy helper object for sending responses back to clients, called IResult.
An IResult contains properties that can be used to represent standard HTTP responses for many different scenarios. For example, we could use IResult to return a specific status code, return JSON data, or even trigger ASP.NET Identity provider functionality such as challenges and sign-in/out.
We can create a new IResult easily using ASP.NET’s Results factory class. In the preceding examples, you will have seen references to this factory class, where the API has returned status codes by calling Results.OK() and Results.Created(), to name a few.
