Question

I see many references to this piece of code on the internets:

if (Request.AcceptTypes.Contains ...

But for the life of me, I cannot find the namespace where this method exists.

We are using MVC4 WebApi, is this MVC3-specific?. Please, before I pull out the rest of my hair.

EDIT:

Going with @Styxxyless answer, this is what I get (no AcceptTypes). I know I am missing something obvious, but what is it?

Also, I have a reference to System.Web in my project.

For MVC, the code is as follows:

Request.AcceptTypes.Contains([MIME type]);

For Web API, the functionality is achieved using the following code:

this.Request.Headers.Accept.Contains(new MediaTypeWithQualityHeaderValue([MIME type]))

or

this.Request.Headers.GetValues("Accept").Contains([MIME type])

An example of a MIME type is: "image/jpeg"
