I have figured out why the components do not show in the Azure ML designer when you create a pipeline as described in those tutorials as the one below:
- When you create a pipeline in designer please make sure you select the Classic tab: Azure ML Studio -> Designer -> New pipeline -> Classic prebuilt (not Custom)
- Click the "+" sign and in the Asset library -> Component you will see the components categories: Sample Data, Data Transformation, Computer Vision, etc.
Hope that helps someone :-)
