The type initializer for 'System.Data.Entity.Migrations.DbMigrationsConfiguration`1' threw an exception.
这是我Configuration.cs：
namespace HRHR.Migrations
{
using System;
using System.Data.Entity;
using System.Data.Entity.Migrations;
using System.Linq;
internal sealed class Configuration : DbMigrationsConfiguration<HRHR.Models.ListofvacanciesEntities>
{
public Configuration()
{
AutomaticMigrationsEnabled = false;
}
protected override void Seed(HRHR.Models.ListofvacanciesEntities context)
{
// This method will be called after migrating to the latest version.
// You can use the DbSet<T>.AddOrUpdate() helper extension method
// to avoid creating duplicate seed data. E.g.
//
// context.People.AddOrUpdate(
// p => p.FullName,
// new Person { FullName = "Andrew Peters" },
// new Person { FullName = "Brice Lambson" },
// new Person { FullName = "Rowan Miller" }
// );
//
}
}
}
这是我的Web.config文件：

问题似乎与App.config部分：无法识别的配置节编译。 –
James P，感谢您抽出时间阅读我的问题。我刚刚添加了Configuration.cs文件和Web.config。 – Taras
您的edmx与MVC应用程序在同一个项目中吗？ –
