I have a question about a project that follows the DDD architecture model.

In a model service I need an information that is the result of a method of another service, what is the correct way to get this information, I create a property of this service and put it in the constructor to do the dependency injection or should I get this information in the previous layer, the same one that I call that first service and pass that value as parameter?

My question is given because I created the second service property and did the dependency injection but then it gave error pq says that there are cyclic dependency injection references and I need to remove the property of that second service and the dependency injection.

It's hard to answer without knowing the context, but I'll try.

If the two services depend on each other, I advise you to create a third service that injects the first two and bridges them.

Example:

Alpha_Service - > UM_Type (BulkService)

Service_Beta - > Two_Type (Alpha_Service)

Delta Service - > Get Alpha and Beta by DI.

Delta Service - > Three-Way () - > Run the Alpha operation by passing Beta as a parameter.

Delta Service - > Fourth Method () - > Run the operation in Beta, passing Alpha as a parameter.
