First KSP Mod. Issues creating a GUI Window

[milbournosphere]

I'm trying my hand at creating my first KSP part mod, but I'm hitting a stumbling block right out of the gate. I found a tutorial here and have tried to complete the first step: create a GUI window for a part module. So here's my newb question.

I'm following this video here:

...which is essentially taking the stock RCS block and rewriting its functionality to bring up a basic GUI window.

The problem is that when I start KSP, I see that the module loads successfully in the log, and I can add the part to a craft in the VAB. When I go to launch it, however, I get no GUI whatsoever. In fact, I don't even see the print statement that I put into OnStart() that I should be seeing in the log. My concern is that this video tutorial set is for a vastly older version of KSP, but KSP's own wiki tutorials follow the same general syntax.

I'm kind of beating my head against the wall because I can't figure what I'm doing wrong. Does anybody have any suggestions or see something wrong with my helloworld code snippet below?

using System;
using UnityEngine;

namespace PluginTutorial{
	public class PluginTutorial : PartModule {
		private Rect _windowPosition = new Rect();

		public override void OnStart(StartState state){
			if (state != StartState.Editor){
				print("[PluginTutorial] start: live");
				RenderingManager.AddToPostDrawQueue(0, OnDraw);
			}
		}

		private void OnDraw(){
			if (this.vessel == FlightGlobals.ActiveVessel)
				_windowPosition = GUILayout.Window(10, _windowPosition, OnWindow, "Title!");
		}

		private void OnWindow(int windowId){
			GUILayout.BeginHorizontal(GUILayout.Width(250f));
			GUILayout.Label("This is a label");
			GUILayout.EndHorizontal();

			GUI.DragWindow();
		}
	}
}

I should also point out that I am new to C#. Thanks for any advice or support.

The first thing I would check is that you are using the right part which has the module correctly spelt in it's config, those tutorials should be good enough yet.

Yep, the problem was in the part config. Had the module name set to the part name, not the module name. That's what I get for coding at midnight. Thanks for the assist!
