AddMigration extension method for non-generic ITypeConfiguration

Hey,

I try to manage my own MigrationSystem for registering migrations by XML model versions for my types. Therefore I’ve a Dictionary with type as key and a List of Migrations (classes based on IEnumerable<Action<XElement>>) as value.

My problem is applying this migrations directly on ConfigurationContainer is not possible because I don’t have generic ITypeConfiguration objects. My algorithmn is:

• Manage my Migration in MigrationSystem (outside in a static configuration manner).
• Iterate over ConfigurationContainer and try to call AddMigration for ITypeConfiguration - if a migration is configured for the type.

But ExtensionMethod AddMigration can only be called for ITypeConfiguration<> and not ConfigurationContainer Enumerator values of type ITypeConfiguration. I’ve also tried to directly use With<MigrationsExtension>.Apply() but this is internal.

Currently workaround is applying migrations directly during creation of ContainerContainer. Therefore I can call Type<> and then AddMigration<>. But this must be done for every type which feels wrong.

Does anyone have a better suggestion? Is it ok to provide a AddMigration extension method for ITypeConfiguration.

Hey @Mike-E-angelo, thx a lot. My tests were successful. It think it should work with this new AddMigration methods. I’ll let you know in case I need anything else in next few days. But for now my demand is covered 😊

As further suggestion: It should be possible to write an AddMigration method for non-generic version of ITypeConfiguration like this. Therefore MigrationExtension must not be exposed. What do you think? Perhaps we could try this too.

public static ITypeConfiguration AddMigration(this ITypeConfiguration @this, IEnumerable<Action<XElement>> migrations)
   => @this.Root.With<MigrationsExtension>()
      .Apply(@this.Get(), migrations.Fixed())
      .Return(@this);
