Pagination.cshtml.cs

public class PaginationModel : PageModel
{
    [BindProperty(SupportsGet = true)]
    public int CurrentPage { get; set; } = 1;
    public int Count { get; set; }
    public int PageSize { get; set; } = 10;

    public int TotalPages => (int)Math.Ceiling(decimal.Divide(Count, PageSize));
}

Your tutorial fails to warn people that it doesn't work with large amounts of data. I have an app that keeps timing out because when GetData() as used here https://www.mikesdotnetting.com/article/328/simple-paging-in-asp-net-core-razor-pages gets too big it gets really slow. To make matters works adding more RAM and caching the GetData() result using LazyCache doesn't solve the problem either.

Please update your tutorial to cover scenarios when GetData() includes over 1,000 rows from a database so that I don't end up getting the entire table. Thank you.

Now all I need is some data. Usually this comes from a database, but I am using some dummy data formatted as JSON that's read from a file. My JSON will deserialise to a collection of Person objects:

It should be clear that the GetData method is there purely to provide some data for the paging demo and is a stand-in for a database. It is not intended to be used with a database. Nevertheless, I'll review the article and see if I can improve it.
