UnityEngine.EventSystems missing while using Visual Studio 2015 RC tools for Unity

Unity Engine

For some reason when I try to add a using statement for EventSystems at the top of my scripts, intellisense seems to have no idea where that namespace is? Anybody have an idea as to what gives? MonoDevelop seems to work fine.

My code, as it is:

using UnityEngine;
using System.Collections;
using UnityEngine.EventSystems;

public class draggableScript : MonoBehaviour, IBeginDragHandler
{

}

Do you have the latest version of ‘Tools for Unity’?

UnityEngine.EventSystems is part of the UnityEngine.UI dll. If you have an older version of ‘Tools for Unity’, it might not be adding the reference to that dll to the project files for use in visual studio.

Try updating to the latest version of ‘Tools for Unity’ and then in unity go to ‘Visual Studio Tools->Generate Project Files’ to regenerate the files for visual studio.
