Question

I have a table which consists of 2 foreign keys. And those are only elements of the table. The table is meant to create association between 2 other tables. For example: The table is Users_Products, and the only 2 columns are UserId and ProductID, both foreign keys. When I generated the EF object from database it didn’t create Users_Products object, it only automatically created navigation properties. Now how can I insert data in my Users_Products table using EF?

Answer 1

You can get some user object and add product into its navigation property.

User user = context.Users.Where(u => u.Id == 1);
Product product = context.Products.Where(p => p.Id == 1);
user.Products.Add(product);
context.SaveChanges();
