Entity Framework Continuous Migrations

What is EF Continuous Migrations?

Entity Framework Continuous Migrations is an EF Core extension for conditionally applying pending migrations to a database at runtime using application configuration settings.

Why would I use it?

You want to ensure the latest EF migrations have been applied during application startup. An example of this would be during an ASP.NET Core application at startup for a given development environment.

How do I use it?

EF Continuous Migrations is added to an application using the AddContinuousMigrations<T> IServicesCollection extension method.

The following example shows how this is done for an ASP.NET Core application in the Startup.ConfigureServices method for an application using a MySql database.

services
    .AddDbContext<ApplicationDbContext>(options =>
        options
            .UseMySql(Configuration.GetConnectionString("DefaultConnection"))
    )
    .AddContinuousMigrations<ApplicationDbContext>()
    .AddControllersWithViews();

EF Continuous Migrations is enabled by default and requires no configuration settings. In order to disable migrations from being applied add the following configuration to a your appsettings.{environment}.json file:

  "ContinuousMigrations": {
    "Enabled": false
  }

A working example can be seen in the Sample application.
