Querying EF Core models

Now that we have a model that maps to the Northwind database and two of its tables, we can write some simple LINQ queries to fetch data. You will learn much more about writing LINQ queries in Chapter 11, Querying and Manipulating Data Using LINQ.For now, just write the code and view the results:

1. In the WorkingWithEFCore project, add a new class file named Program.Helpers.cs.
2. In Program.Helpers.cs, add a partial Program class with a SectionTitle method, as shown in the following code:

partial class Program

    bool useComputerCulture = false)
  {
    // To enable Unicode characters like Euro symbol in the console.
