Most of the regular services used when processing requests (command, projections...), implemented by the application end-developer, that should not be transient or global singletons, will benefit from using the
InTaskScope() life-time scope. This scope ensures the object gets correctly created only once (singleton-like) during a task ran by the framework. A task could be a variety of things (processing a command with command handler, running a background job, processing an event with an async listener...). It is also the scope that most of the framework services visible to the application developer use (repositories, default command handler bindings, etc.).
