As Benoît says,
Dim Normals As New Tile_Normals[TileGrid.Size, TileGrid.Size]
only gives an array where you can store references to Tile_Normals.
You also have to do:
Dim I As Integer
Dim J As Integer
For I = 0 To TileGrid.Size - 1
For J = 0 To TileGrid.Size - 1
Normals[I, J] = New Tile_Normals
Next
Next
Otherwise you will get "null object" errors.
