I've this table here. I;mtring to make computed key as primary key

I can't do it. Is it possible to make computed key a primary key

CREATE TABLE [dbo].[tbltest](
    [menuCode] [varchar](150) NOT NULL,
    [moduleCode] [varchar](150) NULL,
    [menuName] [varchar](150) NULL,
    [menuSource] [nvarchar](500) NULL,
    [active] [bit] NULL,
    [ParentCode] AS moduleCode + '-' + menuCode NOT NULL Primary key,
)

error:

Only UNIQUE or PRIMARY KEY constraints can be created on computed columns, while CHECK, FOREIGN KEY, and NOT NULL constraints require that computed columns be persisted.
