Our modules are interdependent, so we are facing issues, such as reusability of code and unresolved bugs, due to changes in one module. These are deployment challenges. To tackle these issues, let's segregate our application in such a way that we will be able to divide modules into submodules. We can divide our Order module in such a way that it would implement the interface, and this can be initiated from the constructor. Here is a small code snippet that shows how we can apply this in our existing monolithic application.
Here is a code example that shows our Order class, where we use the constructor injection:
namespace FlixOne.BookStore.Common { public class Order : IOrder { private readonly IOrderRepository ...
