我正在使用Identity 1.0 Entity Framework Web应用程序处理MVC5。我试图在我的Migration / Configuration.cs中添加角色，但是我收到了这个错误：
＆＃39; ApplicationDbContext＆＃39;不包含的定义 ＆＃39; ApplicationRole＆＃39;没有扩展方法＆＃39; ApplicationRole＆＃39;验收 类型＆＃39; ApplicationDbContext＆＃39;的第一个参数可以找到（是 你错过了使用指令或程序集引用？）
var roles = new List<ApplicationRole>
{
new ApplicationRole { Id = 1, Name = "Admin"},
new ApplicationRole { Id = 2, Name = "User"},
};
roles.ForEach(s => context.ApplicationRole.AddOrUpdate(p => p.Id, s)); <-- Error on Application Role
context.SaveChanges();
这是我的Roles控制器
