Are there any constants for the default HTTP headers?

Question

Has Microsoft created a class full of constants for the standard HTTP header names or will I have to write my own?

Answer 1

There are some available in the Microsoft.Net.Http.Headers nuget package. In my asp.net core project it was already installed.

Example usage:

var value = request.Headers[Microsoft.Net.Http.Headers.HeaderNames.IfNoneMatch]

Might be what some are looking for?
