Thanks manish for your nice words and encouragements.
You can use IncludeDatabaseContext property like this for your requirement.
scriptOptions.IncludeDatabaseContext = true;
And result will be like this.
USE [AdventureWorks]
SET ANSI_NULLS ON
SET QUOTED_IDENTIFIER ON
CREATE TABLE [HumanResources].[EmployeeAddress](
[EmployeeID] [int] NOT NULL,
[AddressID] [int] NOT NULL,
[rowguid] [uniqueidentifier] ROWGUIDCOL NOT NULL,
[ModifiedDate] [datetime] NOT NULL
) ON [PRIMARY]
Hope it helps.
