EF 7 Beta 8 -> EF7 RC1 - No longer can create migrations

asp.net-core entity-framework-core

Question

After attempting to change my existing project from beta 8 to RC1 I get the following after running 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 
  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'.

My project.json file contains along with others the following

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

What do I need to do to resolve this error?

Package names are case-sensitive on Linux and OS X due to the case-sensitive filesystem. Make sure to use EntityFramework.Sqlite not EntityFramework.SQLite in your project.json file. (See GitHub Issue dotnet/cli#236)
