There is no clear indication whether resolving services from DI is thread safe

Type of issue

Missing information

Description

While there're tips for how to deal with thread safety in our code (singletons) and information about the guaranteed of them being created, there's no general info about whether DI resolving is or isn't thread safe. And I couldn't find it anywhere else either.

It seems it's kinda naturally implied that it must be (and duh, it must be) but it should be very explicitly said somewhere.

It should also be noted as thread safety remarks on the interfaces.
