Regression from EF Core 8 to 9: MigrationBuilder.DropTable Causes Issues with Subsequent Table Recreation

[meghanmae]

Problem

After upgrading from EF Core 8 to EF Core 9, we encountered a regression where using migrationBuilder.DropTable followed by recreating the same table in a single migration causes issues. The issue seems to be resolved when switching to a raw SQL command (migrationBuilder.Sql("DROP TABLE ...");) to drop the table instead of using migrationBuilder.DropTable.

        protected override void Up(MigrationBuilder migrationBuilder)
        {
            // Assuming table Employees was previously created...

            // DropTable: causes the migration to fail
            migrationBuilder.DropTable(
                name: "Employees");

            // Uncomment this (and comment out DropTable) to run the migration successfully 
            //migrationBuilder.Sql("""
            //    Drop Table Employees;
            //    """);

            // Recreate table
            migrationBuilder.CreateTable(
                name: "Employees",
                columns: table => new
                {
                    EmployeeId = table.Column<int>(type: "int", nullable: false)
                        .Annotation("SqlServer:Identity", "1, 1"),
                    Name = table.Column<string>(type: "nvarchar(max)", nullable: false)
                },
                constraints: table =>
                {
                    table.PrimaryKey("PK_Employees", x => x.EmployeeId);
                });
        }
