Join Richard Goforth for an in-depth discussion in this video Solution: Product recall, part of Accessing Existing Databases with Entity Framework Core.
- [Instructor] Now that you've had a chance…to work on your own solution, let me show you…how I solved the product recall challenge.…I started by getting a list of the customers…who ordered the faulty product.…For each customer I wanted to check if any of their…orders had any item that matched the recall.…Here I used where the collection of orders…has any order item that have the product ID…that matches our recalled product.…Next I printed the list of customers to the screen…after ordering them by last name…and using the distinct extension method…to eliminate any duplicates.…
