Learn how to use the Include method in Entity Framework Core to create a one to many relationship query.
This tutorial will involve adding a new entity which will be populated using data seeding and will use EF Core migrations to add it to the SQL Server database.
We'll then use ASP.NET Core Web API endpoints to write LINQ queries that use a one to many relationship. We'll also have a look at inserting and updating a record which has a foreign key.
