Ef6: EF 6.3.0 update-database -ConfigurationTypeName not working

[leandrovip]

After upgrading from EF 6.2 to 6.3 the command 'update-database' not working with more 'configuration type name' in the same solution.

PM> update-database -ConfigurationTypeName VipERP.Data.Migrations.ERP.Configuration -verbose

Workaround

Copy the ef6.exe command and add it there:

D:\Repositorio\VipERP\packages\EntityFramework.6.3.0\tools\net45\win-x86\ef6.exe database update --verbose --no-color --prefix-output --assembly D:\Repositorio\VipERP\source\VipERP.Data\bin\Debug\VipERP.Data.dll --project-dir D:\Repositorio\VipERP\source\VipERP.Data\ --language C# --root-namespace VipERP.Data --config D:\Repositorio\VipERP\source\VipERP.Retaguarda\App.config --migrations-config VipERP.Data.Migrations.ERP.Configuration

This resolved. Thanks

FYI, this fix is included in our daily builds (see link for setup instructions). Feel free to start using it today via the version 6.4.0-preview1-* prerelease packages.

The solution suggested fixed the issue with update-database. But add-migration then still fails with :
Unable to generate an explicit migration because the following explicit migrations are pending: [XXX]. Apply the pending explicit migrations before attempting to generate a new explicit migration
even though I specify a ConfigurationTypeName which is different.

Are multiple contexts supported at all ? Or is it still an experimental feature ?
