Class [..] not found‚Äč

You need to understand the namespace concept as described in section General Concepts (work in progress) Then check:

  • Is the namespace defined in your manifest file?
  • Has every class in your extension the correct namespace?
  • Is every filename correct and matches the namespace?

But the filename is src/Extension/FoosComponent.php
