+ * and file drag&drop support for Windows standalone Unity applications.
+ * 
+ * 2019.11.28 - Changed the "UnityDragAndDropHook" class to a static class. This
+ *   has been done for IL2CPP support. IL2CPP can not marshall instance method
+ *   callbacks passed to native code. So the callbacks must be static methods.
+ *   Therefore all fields involved also need to be static.

+# UnityWindowsFileDrag&Drop
+Adds file drag and drop support for Unity standalone builds on windows.
+
+It uses the GetMessage hook to intercept the WM_DROPFILES message
+
+See the "FileDragAndDrop.cs" or "ImageExample.cs" file for an example usage.
+
+Due to too many issues in the Unity editor (causes random silent crashes) I have disabled the hook when tested in playmode inside the editor. So this feature only works in a build.
