Hello friends. I am developing a web api related to using multiple databases. I've done the Migration part, but I'm stuck in the Controller part. I'm new to Core and didn't know how to act. My codes are on github. Let me share the link. I would be glad if anyone can help.

From your code, there have two dbContext: MultipleDbContext.cs and SharedDbContext.cs, and you have also created some services and Repositories, they also provide some method to manage data via the DbContext, so, I want to confirm with you about that in the Controller, which kind of method you will choose to manage data, via the DbContext, Service or Repositories?
No matter which kind method you will select, in asp.net core we will use Dependency injection to inject the DbContext, Service and Repositories in the controller, more detail information, see Dependency injection in ASP.NET Core and Create controller and views.
Best regards,
Dillion
