I\'m using EF5 with a Database-First model. And a database project in visual Visual Studio to maintain the Sql Server database schema of an application.

Answer 1

I created the project SqlSharpener which should be able to do what you're asking.

For example, given these tables defined in an SSDT project:

CREATE TABLE [dbo].[Tasks]
(
    [Id] INT NOT NULL PRIMARY KEY IDENTITY, 
    [Name] VARCHAR(50) NOT NULL, 
    [Description] VARCHAR(1000) NOT NULL, 
    [TaskStatusId] INT NOT NULL, 
    [Created] DATETIME NOT NULL , 
    [CreatedBy] VARCHAR(50) NOT NULL, 
    [Updated] DATETIME NOT NULL, 
    [UpdatedBy] VARCHAR(50) NOT NULL, 
    CONSTRAINT [FK_Tasks_ToTaskStatus] FOREIGN KEY ([TaskStatusId]) REFERENCES [TaskStatus]([Id])
)

CREATE TABLE [dbo].[TaskStatus]
(
    [Id] INT NOT NULL PRIMARY KEY, 
    [Name] VARCHAR(50) NOT NULL
)

You can create a T4 template that will generate the entities as such:

using System;
using System.Collections.Generic;
using System.ComponentModel.DataAnnotations;
using System.ComponentModel.DataAnnotations.Schema;
using System.Data.Entity;

namespace SimpleExample.EntityFrameworkCodeFirst
{
    public partial class TaskContext : DbContext
    {
        public TaskContext(): base()
        {
        }
        public DbSet Tasks { get; set; }
        public DbSet TaskStatus { get; set; }
    }


    [Table("Tasks")]
    public partial class Tasks
    {

        [Key]
        [Required]
        [DatabaseGenerated(DatabaseGeneratedOption.Identity)]
        public Int32? Id { get; set; }

        [Required]
        [MaxLength(50)]
        public String Name { get; set; }

        [Required]
        [MaxLength(1000)]
        public String Description { get; set; }

        [Required]
        public Int32? TaskStatusId { get; set; }
        [ForeignKey("Id")]
        public virtual TaskStatus TaskStatus { get; set; }

        [Required]
        public DateTime? Created { get; set; }

        [Required]
        [MaxLength(50)]
        public String CreatedBy { get; set; }

        [Required]
        public DateTime? Updated { get; set; }

        [Required]
        [MaxLength(50)]
        public String UpdatedBy { get; set; }
    }

    [Table("TaskStatus")]
    public partial class TaskStatus
    {

        [Key]
        [Required]
        public Int32? Id { get; set; }
        public virtual ICollection Tasks { get; set; }

        [Required]
        [MaxLength(50)]
        public String Name { get; set; }
    }
}

There is a working example of this T4 template in the simple example solution. If there is a use case that SqlSharpener doesn't currently handle, feel free to add an issue and I'll see if I can add it in.
