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,我在运行后得到以下内容 dnx ef migrations add Init

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

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

我的project.json文件包含以下内容

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

我该怎么做才能解决此错误？

Answer 1

由于区分大小写的文件系统,软件包名称在Linux和OS X上区分大小写.确保EntityFramework.Sqlite不要EntityFramework.SQLite在project.json文件中使用not .(参见GitHub Issue dotnet/cli#236)
