Reference for BasePlayer?

I have visual studio community software 2013 (free)
https://www.visualstudio.com/en-us/products/visual-studio-community-vs.aspx

In my project, I have set references to all the Oxide dll's in the RustDedicated_Data\Managed folder, so I can use intellisense on them (explore methods/arguments and such, autocomplete etc).

I noticed, that many plugins use the BasePlayer type. When I use this, I get a squigly line in visual studio, indicating I should set a reference. But I dont know what dll BasePlayer resides in. The code runs just fine.

How do I get intellisense working for BasePlayer?

Test01.cs in plugins folder:

Code:

// Reference: Oxide.Ext.Rustusing System;
namespace Oxide.Plugins
{
    [Info("Test01", "Bas", "0.1.0", ResourceId = 99681)]
    public class Test01 : RustPlugin
    {
        int authLevel = 2;        [ChatCommand("authLevel")]
        void cmdChatAuthLevel()
        {
            Console.WriteLine("authLevel={0}", authLevel);
        }        [ChatCommand("setAuthLevel")]
        void cmdChatSetAuthLevel(BasePlayer player, string command, string[] args)
        {
            authLevel = Convert.ToInt32(args[0]);
            cmdChatAuthLevel();
        }
    }  
}

 

I downloaded as a zip the Oxide-project from github https://github.com/OxideMod/Oxide
Extracted, open with visual studio, search for 'BasePlayer'

It turns out BasePlayer is defined in RustDedicated_Data\Managed\Assembly-CSharp.dll
Setting a reference to Assembly-CSharp.dll in my plugin-project did the trick.
