Solved The type or namespace name `Tuple' could not be found

Hi everyone,

I am currently working on a solution to make one of my mods easier, I was planning on using Tuple and Dictionary in the OnEntityTakeDamage, here is the function that I was making:

Code:

        public sealed class MyKey : Tuple<Type, Type>
        {
            public MyKey(Type dataA, Type dataB) : base(dataA, dataB) { }            public Type DataA { get { return Item1; } }            public Type DataB { get { return Item2; } }
        }        Dictionary<MyKey, string> myDictinaryData = new Dictionary<MyKey, string>()
        {
            { new MyKey(typeof(BasePlayer), typeof(BasePlayer)), "Player V Player"},
            { new MyKey(typeof(BasePlayer), typeof(AutoTurret)), "Player V Turret"},
            { new MyKey(typeof(BasePlayer), typeof(BaseNpc)), "Player V NPC"},
            { new MyKey(typeof(AutoTurret), typeof(BasePlayer)), "Turret V Player"}
        };

The issue is that in rust I get this error:

Code:

Error while compiling: PvXSelector.cs(691,37): error CS0246: The type or namespace name `Tuple' could not be found. Are you missing an assembly reference?

I just want to confirm if Turpe is supported or if I have to use an alternative, if I do have to use an alternative does anyone have any recommendations/suggestions thanks.
