EntityFrameworkCore

This article describes how to use Orca with EntityFrameworkCore store.

Setup

First add the Orca.Store.EntityFrameworkCore package into your project.

.NET CLI

dotnet add package Orca.Store.EntityFrameworkCore

Package Manager

Install-Package Orca.Store.EntityFrameworkCore

In the Program.cs, register the EntityFrameworkCore store:

builder.Services
  .AddOrca()
  .AddEntityFrameworkStores<ContosoDbContext>();

builder.Services.AddDbContext<ContosoDbContext>((sp, options) => {
  var configuration = sp.GetRequiredService<IConfiguration>();

  options.UseSqlServer(configuration.GetConnectionString("Default"), sqlServerOptions =>
  {
      sqlServerOptions.MigrationsAssembly(Assembly.GetExecutingAssembly().FullName);
  });
});

AddEntityFrameworkStores method configures Orca stores to use EntityFramework persistence.

The DbContext to be configured must inherit from OrcaDbContext.

Migrations

To create a migration named InitialCreate:

.NET CLI

dotnet ef migrations add InitialCreate

PowerShell

Add-Migration InitialCreate

To apply the migration and create the database schema:

.NET CLI

dotnet ef database update

PowerShell

Update-Database

At this point the database should be created.
