In .NET Core, tight coupling and loose coupling refer to the way software components are designed and connected to each other. Tight coupling in .NET Core means that two or more software components are highly dependent on each other, making it difficult to modify or replace one component without affecting the others. This can lead to maintenance and testing challenges, as well as reduced flexibility and scalability. Loose coupling in .NET Core, on the other hand, means that software components are designed to be independent and have minimal interdependence. This is achieved by using interfaces, dependency injection, and other techniques to reduce the direct dependencies between components. Loose coupling allows components to be more easily replaced, modified, or extended without affecting the rest of the system. Summary, loose coupling is generally preferred in .NET Core because it makes software more flexible, maintainable, and scalable. Advant...
