Key Chain. Query AsConcrete Type(SecRecord, SecStatusCode) Method
public static object QueryAsConcreteType (Security.SecRecord query, out Security.SecStatusCode result);
static member QueryAsConcreteType : Security.SecRecord * -> obj
The query used to lookup the value on the keychain.
Returns the status code from calling SecItemCopyMatching.
This method will throw an exception if the KeyChain contains a new data type that you have introduced with a newer version of Xamarin.iOS into the keychain and you then try to use this with an older version that does not have the ability of decoding theve value.
This is the strongly typed equivalent of calling the Security's framework SecItemCopyMatching method with the kSecReturnRef set to true.
