You are working on an ASP.NET Core application and need to model a scenario where each Order can have multiple OrderDetails, but each OrderDetail belongs to one Order. How would you model this relationship using Entity Framework Core?

In this scenario, you should use a One-to-Many Relationship. Each Order can have multiple OrderDetails, creating a parent-child relationship. You can achieve this by defining a navigation property in the Order class pointing to a collection of OrderDetails, and a reference property in the OrderDetail class pointing back to the Order.
