Running Migrations

Running your migrations are quite easy. Just get all of your migration out of your IoC container (in order).

var migrations = _container.Resolve<IEnumerable<IMigration>>()
                           .OrderBy(x => typeof (IMigration).Name)
                           .ToList();

Create a new MigrationRunner, passing in the DbProvider being used.

var migrationRunner = new MigrationRunner(_container.Resolve<IDbProvider>());

And then simply RunAll

 migrationRunner.RunAll(SystemRole.Client, migrations);

Here's a complete example of how we register the DbProvider
note: Registering your Migrations is straight forward, just register them the way you register everything else, and do it in the PCL

Platform Specific - IDbProvider Registration

SQLite

// Inside the the platform specific code
//    AppDelegate (iOS)
//    MainActivity (Android)
containerBuilder.RegisterType<DbProvider>()
                .SingleInstance()
                .WithParameters(new List<Parameter> {
                    new TypedParameter(typeof(string), "database.sqlite3"),
                    new TypedParameter(typeof(SqliteSettings), new SqliteSettings {
                        CacheSize = 16777216,
                        SyncMode = SynchronizationModes.Off,
                        JournalMode = SQLiteJournalModeEnum.Off,
                        PageSize = 65536
                    })
                })
                .As<IDbProvider>();

SQL Server

var dbConnection = ConfigurationManager.ConnectionStrings["databaseConnection"];
var databaseName = ConfigurationManager.AppSettings["databaseName"];

var connectionProvider = new DbConnectionProvider(dbConnection.ConnectionString, dbConnection.ProviderName);
var dbProvider = new DbProvider(connectionProvider, databaseName);
containerBuilder.RegisterInstance(dbProvider).As<IDbProvider>().SingleInstance();

Portable Class Library - Run Migrations

private static void RunMigrations()
{
    var migrations = _container.Resolve<IEnumerable<IMigration>>()
                               .OrderBy(x => typeof (IMigration).Name)
                               .ToList();

    var migrationRunner = new MigrationRunner(_container.Resolve<IDbProvider>());
    migrationRunner.RunAll(SystemRole.Client, migrations);
}

note: these examples are shown using Autofac as the IoC container. You're free to use whatever IoC Container you like.
