Description Adam Kemp 2015-02-16 14:56:11 UTC
NSArray should implement IEnumerable<T>, IReadOnlyCollection<T>, IReadOnlyList<T>.

NSMutableArray should implement the above plus IList<T>.

NSSet should implement IReadOnlyCollection<T>. Sadly there is no IReadOnlySet<T>. :(

NSMutableSet should implement ISet<T> and ICollection<T>.

NSDictionary should implement IReadOnlyDictionary<TKey, TValue>. It should _not_ implement IDictionary<TKey, TValue> or ICollection<T> (though this would be a breaking change).

NSMutableDictionary should implement IReadOnlyDictionary<TKey, TValue>.

All of these help tremendously in working with these data types in cross-platform code in an efficient way.

I have checked this issue and observed the reported behaviour. I’ll need confirmation from the developer if this is a bug. For now I am leaving this bug as NEW.

Postponed to a future release (non trivial code size impact)
