Question

当我尝试在我的数据库项目（EF 6.1.0 stable）中启用迁移时，它会抛出一个MissingMethodException：

Enable-Migrations -Verbose -Debug
Using StartUp project 'xxx.Data'.
Using NuGet project 'xxx.Data'.
System.MissingMethodException: Method not found: 'Void System.Data.Entity.Migrations.Design.ToolingFacade..ctor(System.String, System.String, System.String, System.String, System.String, System.String, System.Data.Entity.Infrastructure.DbConnectionInfo)'.
   at System.Data.Entity.Migrations.MigrationsDomainCommand.GetFacade(String configurationTypeName, Boolean useContextWorkingDirectory)
   at System.Data.Entity.Migrations.EnableMigrationsCommand.FindContextToEnable(String contextTypeName)
   at System.Data.Entity.Migrations.EnableMigrationsCommand.<>c__DisplayClass2.<.ctor>b__0()
   at System.Data.Entity.Migrations.MigrationsDomainCommand.Execute(Action command)
Method not found: 'Void System.Data.Entity.Migrations.Design.ToolingFacade..ctor(System.String, System.String, System.String, System.String, System.String, System.String, System.Data.Entity.Infrastructure.DbConnectionInfo)'.

任何人都有指针给我？

通过降级到EF 5.0.0，启用迁移，将程序包更新到6.1.0来修复它。
