Hi,

when changing an entity key from DatabaseGeneratedOption.None to DatabaseGeneratedOption.Identity the following migration code block will throw an exception:

Code: Select all

DropPrimaryKey("dbo.TestTables");
AlterColumn("dbo.TestTables", "TestTableID", c => c.Int(nullable: false, identity: true));
AddPrimaryKey("dbo.TestTables", "TestTableID");

The exception says "serial does not exist". I also sent you an sample project to reproduce this issue.

The bug related to the "Type 'serial' doesn't exist" error while performing the ALTER TABLE statement via Code-First migrations is fixed.
