Reflection for building EntityTypeConfiguration list for Entity Framework CPT5

I do not want each mapping class to be manually added to ModelBuilder (), so I tried to use my limited reflection knowledge to register them. This is what I have, and this is the error I get:

CODE:

private static ModelBuilder CreateBuilder() {
            var contextBuilder = new ModelBuilder();
            IEnumerable<Type> configurationTypes = typeof(DatabaseFactory)
                .Assembly
                .GetTypes()
                .Where(type => type.IsPublic && type.IsClass && !type.IsAbstract && !type.IsGenericType && typeof(EntityTypeConfiguration).IsAssignableFrom(type) && (type.GetConstructor(Type.EmptyTypes) != null));

            foreach (var configuration in configurationTypes.Select(type => (EntityTypeConfiguration)Activator.CreateInstance(type)))
            {
                contextBuilder.Configurations.Add(configuration);
            }

            return contextBuilder;
        }

Error: Error 2 Type arguments for the method "System.Data.Entity.ModelConfiguration.Configuration.ConfigurationRegistrar.Add (System.Data.Entity.ModelConfiguration.EntityTypeConfiguration)" cannot be taken out of use.
