配置VS localDB和EF部署

Question

我在這裏看到了幾個問題，但我找不到解決方案。

我有一個winform應用程序VS2013與EF運行一個LocalDB。這個LocalDB是從模型創建的。

我應該怎麼做才能在客戶端上使用LocalDB安裝此應用程序？

我是否需要向解決方案添加MDF文件？ 要做什麼？

有類似的問題：localDB Deployment，Installer

1. 你可能已經安裝了 「的LocalDB」。 您的客戶需要一個安裝程序。

您需要填充種子數據。看到這個帖子：

Recreate and Reseed LocalDb Before Each Unit Test

public class MyDatabaseInitializer :  System.Data.Entity.DropCreateDatabaseAlways<MyDbContext> 
{ 
    protected override void Seed(MyDbContext context) 
    { 
     // Add entities to database. 

     context.SaveChanges(); 
    } 
} 

您的客戶端應用程序將需要正確的連接字符串。

Server=(localdb)\v11.0;Integrated Security=true; 
AttachDbFileName=C:\MyFolder\MyData.mdf; 

但隨着 「種子數據」 overload..it應該能夠動態地創建它。

這裏是做一個例子，只是我相信：

namespace ContosoUniversity.DAL 
{ 
    public class SchoolInitializer : System.Data.Entity.DropCreateDatabaseIfModelChanges<SchoolContext> 
    { 
     protected override void Seed(SchoolContext context) 
     { 
      var students = new List<Student> 
      { 
      new Student{FirstMidName="Carson",LastName="Alexander",EnrollmentDate=DateTime.Parse("2005-09-01")}, 
      new Student{FirstMidName="Meredith",LastName="Alonso",EnrollmentDate=DateTime.Parse("2002-09-01")}, 
      new Student{FirstMidName="Arturo",LastName="Anand",EnrollmentDate=DateTime.Parse("2003-09-01")}, 
      new Student{FirstMidName="Gytis",LastName="Barzdukas",EnrollmentDate=DateTime.Parse("2002-09-01")}, 
      new Student{FirstMidName="Yan",LastName="Li",EnrollmentDate=DateTime.Parse("2002-09-01")}, 
      new Student{FirstMidName="Peggy",LastName="Justice",EnrollmentDate=DateTime.Parse("2001-09-01")}, 
      new Student{FirstMidName="Laura",LastName="Norman",EnrollmentDate=DateTime.Parse("2003-09-01")}, 
      new Student{FirstMidName="Nino",LastName="Olivetto",EnrollmentDate=DateTime.Parse("2005-09-01")} 
      }; 

      students.ForEach(s => context.Students.Add(s)); 
      context.SaveChanges(); 
      var courses = new List<Course> 
      { 
      new Course{CourseID=1050,Title="Chemistry",Credits=3,},

      new Course{CourseID=2042,Title="Literature",Credits=4,} 
      }; 
      courses.ForEach(s => context.Courses.Add(s)); 
      context.SaveChanges(); 
      var enrollments = new List<Enrollment> 
      { 
      new Enrollment{StudentID=1,CourseID=1050,Grade=Grade.A}, 
      new Enrollment{StudentID=1,CourseID=4022,Grade=Grade.C},

      new Enrollment{StudentID=2,CourseID=3141,Grade=Grade.F}, 
      new Enrollment{StudentID=2,CourseID=2021,Grade=Grade.F}, 
      new Enrollment{StudentID=3,CourseID=1050}, 
      new Enrollment{StudentID=4,CourseID=1050,}, 
      new Enrollment{StudentID=4,CourseID=4022,Grade=Grade.F}, 
      new Enrollment{StudentID=5,CourseID=4041,Grade=Grade.C}, 
      new Enrollment{StudentID=6,CourseID=1045}, 
      new Enrollment{StudentID=7,CourseID=3141,Grade=Grade.A}, 
      }; 
      enrollments.ForEach(s => context.Enrollments.Add(s)); 
      context.SaveChanges(); 
     } 
    }
