EF7 has new sytax from DBContextOptionsBuilder to EntityOptionsBuilder. Following is ready to use for also command line scaffolding.

public class ContentContext : DbContext
{
    public DbSet Contents { get; set; }
    public DbSet ContentCategories { get; set; }

    protected override void OnConfiguring(EntityOptionsBuilder optionsBuilder)
    {
        optionsBuilder.UseSqlServer("Data:DefaultConnection:ConnectionString");
    }
}
