UnityEditor.EditorApplication.update called only once

Exactly as the title says
This is the code:

Code (csharp):

1. #if UNITY_EDITOR
2.     [ExecuteInEditMode, UnityEditor.InitializeOnLoad]
3. #endif
4.     public class GrassTile : MonoBehaviour, ISerializationCallbackReceiver {
5.  
6. #if UNITY_EDITOR
7.         public static void EditorUpdate() {
8.             Debug.Log("EditorUpdate");
9.         }
10.         static GrassTile() {
11.             UnityEditor.EditorApplication.update += EditorUpdate;
12.             Debug.Log("GrassTile");
13.         }
14. #endif
15.     }

this is the console output:

Code (csharp):

1. GrassTile                                                                            (1)
2. EditorUpdate                                                                         (1)

What did I do wrong? It should be spamming my console with "EditorUpdate" but it's not
As a workaround I am using

Code (csharp):

1.         public static void EditorUpdate() {
2.             Debug.Log("EditorUpdate");
3.             UnityEditor.EditorApplication.delayCall += EditorUpdate;
4.         }

But I'd rather do it the 'right way'

 

My own approach wasn't any better than the one you ended up with. You can see the results in the thread linked below but basically there isn't a 'right way' for this because it's simply not intended behaviour.
