Visual studio 2013 获取表时出错,我没有使用实体框架代码优先方法创建该表。错误是无效的对象名称“0”;XXXX“;
初始迁移代码在下面,我从未创建过Visual studio 2013 获取表时出错,我没有使用实体框架代码优先方法创建该表。错误是无效的对象名称“0”;XXXX“;,visual-studio-2013,asp.net-mvc-5,ef-code-first,ef-code-first-mapping,Visual Studio 2013,Asp.net Mvc 5,Ef Code First,Ef Code First Mapping,初始迁移代码在下面,我从未创建过dbo.StudentEvent1,但使用此数据库运行asp.net MVC应用程序时出错 CreateTable( "dbo.StudentEvents", c => new { StudentId = c.Int(nullable: false), EventId = c.Int(nullable
dbo.StudentEvent1
,但使用此数据库运行asp.net MVC应用程序时出错
CreateTable(
"dbo.StudentEvents",
c => new
{
StudentId = c.Int(nullable: false),
EventId = c.Int(nullable: false),
isAttended = c.Boolean(nullable: false),
})
.PrimaryKey(t => new { t.StudentId, t.EventId })
.ForeignKey("dbo.Events", t => t.EventId, cascadeDelete: true)

打开package manager控制台并选择默认项目 然后,
启用迁移
用于启用迁移
然后将添加迁移
添加到迁移中的更改中
然后将更新数据库应用于数据库
