Adds the set of CreateResponse/CreateErrorResponse extension methods that
return an HttpResponseMessage.
For the overloads that perform content negotiation they will access the
collection of MediaTypeFormatters through the shim options. Note that
CreateResponse and friends use the OLD formatters.
Also, HttpError and CreateErrorResponse assume ErrorDetail == false. Using
the shim you will not get detailed error messages unless you construct the
HttpError instance yourself.
This change adds a ModelBinder that can bind an HttpRequestMessage to an
action parameter.
This builds on an earlier change to construct and store the request
message in the HttpContext via an http feature.
This change adds a .Request property to the ApiController class that can
be used to access an HttpRequestMessage wrapping the HttpContext.
The HttpRequestMessage is stored in an http feature to make it accessible
to model binders and other infrastructure.
