Solved Starting out with C# plugins, import issue?

Hello! So i'm new to Oxide modding and would like to grasp the basic concept of how it works to start working on my own fancy mods. so here I go...

Any reason why this is not working at all?

Code:

using System.Collections.Generic;
using System;
using System.Reflection;
using System.Data;using UnityEngine;using Oxide.Core;
using Oxide.Core.Configuration;
using Oxide.Core.Plugins;using Oxide.Rust;namespace Oxide.Plugins
{
    [Info("Testing Rust fuctionality", "Zuen Studio", "1.0.0")]
    public class TestingFunctions : RustPlugin
    {
        [ChatCommand("testme")]
        void TestMecc(BasePlayer player, string command, string[] args)
        {
            MessageAllPlayers("Hello");
        }
    }
}

In-game tryping "/testme " results in "unknown command 'testme'!"

 

Derp easy enough fix Thanks!... the using statements was me going mad for it not working initially. So i'm using VS2012 and I added my references but i still don't have the required reference for BasePlayer ... what dll would that be located in exactly?

 

I must say that the solutions to my problems are so simple I feel really stupid to not see them. Thanks.

 

okay so I got the thing pretty much figured out to a point but ... What is the best approach to check what current belt item the player is holding in his hand if he is holding one?
