asp.net-core - EF 7 Beta 8 -> EF7 RC1 - 不再可以创建迁移

Question

尝试将现有项目从 beta 8 更改为 RC1 后，我在运行 dnx ef migrations add Init 后得到以下信息

System.TypeLoadException: Could not load type 'Microsoft.Data.Entity.Scaffolding.SqliteDesignTimeServices, EntityFramework.Sqlite.Design'.
  at Microsoft.Data.Entity.Design.Internal.DesignTimeServicesBuilder.ConfigureProviderServices (System.String provider, IServiceCollection services, Boolean throwOnError) [0x00000] in <filename unknown>:0 
  at Microsoft.Data.Entity.Design.Internal.DesignTimeServicesBuilder.Build (Microsoft.Data.Entity.DbContext context) [0x00000] in <filename unknown>:0

Could not load type 'Microsoft.Data.Entity.Scaffolding.SqliteDesignTimeServices, EntityFramework.Sqlite.Design'.

我的 project.json文件与其他人一起包含以下内容

"dependencies": {
  "EntityFramework.Commands": "7.0.0-rc1-final",
  "EntityFramework.SQLite": "7.0.0-rc1-final"
},
"commands": {
  "ef": "EntityFramework.Commands"
},

我需要做什么来解决这个错误？

Answer 1

由于文件系统区分大小写，包名称在 Linux 和 OS X 上区分大小写。确保使用 EntityFramework.Sqlite不是 EntityFramework.SQLite在您的 project.json 文件。 (参见 GitHub 问题 dotnet/cli#236)
