When consuming NSError exceptions raised by Objective-C, I wrote an exception
class to translate the NSError to a Exception to make exception handling
uniform.

I was expecting the following NSError constants to be on the NSError class. Am
I missing the location of these constants or were they not translated into
MonoTouch?

NSString * const NSLocalizedDescriptionKey;
NSString * const NSErrorFailingURLStringKey;
NSString * const NSFilePathErrorKey;
NSString * const NSStringEncodingErrorKey;
NSString * const NSUnderlyingErrorKey;
NSString * const NSURLErrorKey;
NSString * const NSLocalizedFailureReasonErrorKey;
NSString * const NSLocalizedRecoverySuggestionErrorKey;
NSString * const NSLocalizedRecoveryOptionsErrorKey;
NSString * const NSRecoveryAttempterErrorKey;
NSString * const NSHelpAnchorErrorKey;
NSString * const NSURLErrorFailingURLErrorKey;
NSString * const NSURLErrorFailingURLStringErrorKey;
NSString * const NSURLErrorFailingURLPeerTrustErrorKey;
