The solution I came up with recently is to use single context for both ASP.NET identity data and your business entities:

public class DatabaseContext : IdentityDbContext<UserInfo>
{
    public virtual DbSet<Comment> Comments { get; set; } // Your business entities

    public DatabaseContext()
        : base("name=DatabaseContext")
    {
    }
}

Notice that the DatabaseContext inherits from the IdentityDbContext<UserInfo>.

There are some trade-offs with this approach: for example, your data access layer should reference Microsoft.AspNet.Identity.Core and Microsoft.AspNet.Identity.EntityFramework; however, having a single database context in your project makes things much easier if you are using dependency injection or Entity Framework migrations.
