But I expect you already know that and just want to know why not to just inject a new instance (i.e. with a transient lifestyle) of the DbContext into anyone who needs it.

...reason why it is so hard to get right is because you must have a complete knowledge of the threading behaviour of the entire program in order to ensure its safety.
Again, look at my example: every method is trivial. It is the way that the methods interact with each other at a "global" level that m...
