Question

I have two database each with their own dbcontext. I\'ve setup two migration configurations. I can add a migration for the first db ust fine (Add-Migration DB1_Initial

Answer 1

I've been able to answer my own question. My two configuration classes existed in the same namespace. As soon as I separated them, everything worked.

Answer 2

With Entity Framework 6 it's easy.

It's the same procedure for both multiple DbContexts for one database and for multiple DbContexts for each their own database:

Enable-Migrations -ContextTypeName <DbContext-Name-with-Namespaces> -MigrationsDirectory:<Migrations-Directory-Name>

Add-Migration -configuration <DbContext-Migrations-Configuration-Class-with-Namespaces> <Migrations-Name>

Update-Database -configuration <DbContext-Migrations-Configuration-Class-with-Namespaces> -Verbose

It's been a while, but this could be a better answer to your problem :)

Update-Database -ConfigurationTypeName "SlaveConfiguration"
                -StartupProjectName "FacturatieMVCv2.Data" -Verbose 
                -ConnectionString "connstring;" 
                -ConnectionProviderName "System.Data.SqlClient"
