MigrationStage.AfterAll doesn't get executed when registering migrations via .ScanIn(typeof(Program).Assembly).For.Migrations()

When trying to run a Maintainance script on sql server it doesn’t get executed. I’ve tried to step into the source and it seems like AssemblySourceOptions doesn’t return any assemblies. My entire source is here. I use .net core. What is the problem. I cannot find documentation on this.

My goal is to have all stored proc applied on the database on every single Migrate run - via the class Id_999999999999_RunAllStoredProcedures.

class Program
    {
        static void Main(string[] args)
        {
            IServiceCollection services = new ServiceCollection();
            const string connectionString = @"Server=.\SQLEXPRESS;Database=Cv;Trusted_Connection=true";
            services
                .AddFluentMigratorCore()
                .ConfigureRunner(
                    x => x.AddSqlServer2016()
                        .WithGlobalConnectionString(connectionString)
                        .ScanIn(typeof(Program).Assembly).For.Migrations());
            var provider = services.BuildServiceProvider();

            using (IServiceScope scope = provider.CreateScope())
            {
                IMigrationRunner runner = scope.ServiceProvider.GetRequiredService<IMigrationRunner>();
                runner.MigrateUp();
            }
        }
    }

    [Migration(1)]
    public class TestMigration : Migration
    {
        /// <inheritdoc />
        public override void Up()
        {
            Create.Table("test").WithColumn("Id").AsString();
        }

        /// <inheritdoc />
        public override void Down()
        {
            throw new NotImplementedException();
        }
    }

    [Maintenance(MigrationStage.AfterAll)]
    public class Id_999999999999_RunAllStoredProcedures : Migration
    {
        public override void Up()
        {
            Execute.Sql("CREATE OR ALTER PROC a AS BEGIN SELECT 1 END");
        }

        public override void Down()
        {
            //NOOP
        }
    }

Hi, I would like to add that issue still exists. I start today work with FluentMigrator and I spent 3 hours to find this ticket, which has a workaround. It would be good to update documentation how to write In-Process application with working MaintenaceAttribute. https://fluentmigrator.github.io/articles/migration-example.html https://fluentmigrator.github.io/articles/glossary.html

In summary: workaround which adds IAssemblySourceItem (I don’t know what it is, I just start play with FluentMigrator) which suggests @jzabroski works.

I also found another workaround without adding IAssemblySourceItem: Changing .ScanIn(typeof(Program).Assembly).For.Migrations() to .ScanIn(typeof(Program).Assembly).For.All() also works.

I tried also combination, but this doesn’t work.

.ScanIn(typeof(Program).Assembly)
    .For.Migrations()
    .For.EmbeddedResources()
    .For.VersionTableMetaData()

After following this process, the error still persists what change is I targeted my migration file to be in my .net core API project directory, not the class library project. “It works for me”
