[Solved] Need Help with Visual Studio

I have Visual Studio 2019 Installed, and the MDK Installed.

If I do anything with the GridTerminalSystem object it always returns null, and causes an exception.

Even Simply adding this line to my Main method will throw the exception.
Echo(GridTerminalSystem.GetType().ToString());

I can't find an answer anywhere, my google fuu is failing and I tried searching for a forum post mentioning something like this, but I am coming up short.

Do I not have my IDE setup correctly?

Code:

System.NullReferenceException
  HResult=0x80004003
  Message=Object reference not set to an instance of an object.
  Source=Light-Finder
  StackTrace:
  at IngameScript.Program.Main(String argument, UpdateType updateSource) in C:\Users\<User>\source\repos\Light-Finder\Program.cs:line 34

My code is simply as follows.

Code:

using Sandbox.Game.EntityComponents;
using Sandbox.ModAPI.Ingame;
using Sandbox.ModAPI.Interfaces;
using SpaceEngineers.Game.ModAPI.Ingame;
using System.Collections.Generic;
using System.Collections;
using System.Linq;
using System.Text;
using System;
using VRage.Collections;
using VRage.Game.Components;
using VRage.Game.GUI.TextPanel;
using VRage.Game.ModAPI.Ingame.Utilities;
using VRage.Game.ModAPI.Ingame;
using VRage.Game.ObjectBuilders.Definitions;
using VRage.Game;
using VRage;
using VRageMath;

namespace IngameScript
{
	partial class Program : MyGridProgram
	{
		public Program()
		{
		}

		public void Save()
		{
		}

		public void Main(string argument, UpdateType updateSource)
		{
			Echo(GridTerminalSystem.GetType().ToString());
		}
	}
}

I found my Answer. The GridTerminalSystem needs to be prepoluated, with a mockup.
