What would the purpose be for you to make a class singleton? If you need singleton behaviour your are better off using a DI framework and configuring the instance as singleton in the registration part of the DI.

Thanks for your feedback. DI is an interesting choice. In fact the modern DI containers such as AutoFac has the notion of scoped dependency configurations and thus the configuration is by no means static. Rather it is instance-based. I'll update the text with an example.

What do you mean intelligently?please give some examples.
