- If everything in the class is static, consider making it a static class. That way, you won’t get a constructor at all.
- If you want a parameterless constructor but you don’t want it to be public, declare it explicitly and make it private (or internal etc)
- If you don’t want a parameterless constructor but do want constructors with parameters, then just declare the parameterized constructor – the default constructor won’t be generated for you
I think that should cover all bases…
