Code.DotNet.App.EntityFrameworkCore

Extend Entity Framework DbContext scaffolding to make DbContext use ChangeTrackingStrategy.ChangingAndChangedNotifications and to make each entity class implement INotifyPropertyChanging and INotifyPropertyChanged interfaces.

Getting started

1. Add new Console App project (here called MyScaffoldingStartupProject) which will be used as a startup project for Entity Framework Core DbContext scaffolding

2. Add reference to the target project (here called MyTargetProject) to which Entity Framework Core context and models would be generated

3. Install NuGet packages using NuGet Package Manager Console:

   Install-Package Code.DotNet.App.EntityFrameworkCore -ProjectName MyScaffoldingStartupProject
   Install-Package Microsoft.EntityFrameworkCore.Tools -ProjectName MyScaffoldingStartupProject
   Install-Package Microsoft.EntityFrameworkCore.SqlServer -ProjectName MyScaffoldingStartupProject
   

4. Update Program.cs file to include design-time services configuration:

   using Microsoft.EntityFrameworkCore.Design;
   using Microsoft.Extensions.DependencyInjection;
   using Code.DotNet.App.EntityFrameworkCore;
   
   namespace MyScaffoldingStartupProject
   {
       class Program
       {
           static void Main(string[] args)
           {
           }
       }
   
       class CustomDesignTimeServices : IDesignTimeServices
       {
           public void ConfigureDesignTimeServices(IServiceCollection services)
           {
               services.AddCSharpNotificationEntityImplementation();
           }
       }
   }
   

5. Run Scaffold-DbContext using NuGet Package Manager Console (change arguments to match your configuration):

   Scaffold-DbContext "Server=(localdb)\mssqllocaldb;Database=Blogging;Trusted_Connection=True;" Microsoft.EntityFrameworkCore.SqlServer -Project MyTargetProject -StartupProject MyScaffoldingStartupProject -OutputDir Models -ContextDir Context -Verbose -UseDatabaseNames
