# About

![immg](assets/efcore_csharp.png)

This repository is for teaching using Microsoft Entity Framework Core with a modified version of Microsoft [NorthWind database](https://gist.github.com/karenpayneoregon/40a6e1158ff29819286a39b7f1ed1ae8).

First lesson walkthrough building the foundation for

- Reading data with and without related data with EF Core and SQL-Server data provider

- Using projections

- Unit testing

- Various [DbContext](https://docs.microsoft.com/en-us/dotnet/api/microsoft.entityframeworkcore.dbcontext?view=efcore-5.0) configurations

  - Including [ProxiesExtensions](https://docs.microsoft.com/en-us/dotnet/api/microsoft.entityframeworkcore.proxiesextensions?view=efcore-5.0) 

- Reverse Engineering a database using [EF Power Tools](https://marketplace.visualstudio.com/items?itemName=ErikEJ.EFCorePowerTools)

- Source control, [GitHub](https://github.com/) in Visual Studio

# Sample test methods

```csharp

namespace NorthWindCoreUnitTest

{

    [TestClass]

    public partial class CustomersTest : TestBase

    {

        [TestMethod]

        [TestTraits(Trait.EfCoreCustomersSelect)]

        public void CustomerCount()

        {

            using var context = new NorthwindContext();

            

            var customers = context.Customers.ToList();

            Assert.IsTrue(customers.Count == 91);

        }

        [TestMethod]

        [TestTraits(Trait.EfCoreCustomersSelect)]

        public async Task CustomersProject()

        {

            var customers = 

                await CustomersOperations.GetCustomersWithProjectionAsync();

            string firstName = customers

                .FirstOrDefault(cust => cust.FirstName == "Maria").FirstName;

            

            Assert.IsTrue(firstName == "Maria");

        }

    }

}

```
