From case file:
"On Windows 8.1 with .NET 4.5, I can do the following (where hrm is an HttpRequestMessage)...

hrm.Headers.Add("Accept", "application/vnd.citrix.requesttokenresponse+xml, application/vnd.citrix.requesttokenchoices+xml");

On Xamarin.iOS, this is throwing a run-time System.FormatException.

Thoughts, please? I'm fine with altering my code in any way, so long as I can get the same effect on both platforms. Thanks!"

From me:
I confirmed this behavior. Test projects are attached.
Comment 3 Miguel de Icaza [MSFT] 2014-01-10 13:34:11 UTC
For now, split the two mime types into separate calls to Add like this:

hrm.Headers.Add("Accept", "application/vnd.citrix.requesttokenresponse+xml");
hrm.Headers.Add("Accept", "application/vnd.citrix.requesttokenchoices+xml");
Comment 4 Dominique Louis 2014-01-10 14:32:59 UTC
Another alternative is....

hrm.Headers.Accept.Add(new MediaTypeWithQualityHeaderValue("application/vnd.citrix.requesttokenresponse+xml"));
hrm.Headers.Accept.Add(new MediaTypeWithQualityHeaderValue("application/vnd.citrix.requesttokenchoices+xml"));
