ASP.NET Identity need help getting to respective logged in user's row in AspNetUsers table

Hello all,
What the title says, I need to know how to get to that row. Here's what I've tried already from the internet:

string aspNetUserId = System.Security.Principal.WindowsIdentity.GetCurrent().GetUserId(); //returns nothing (null)

string aspNetUserId = System.Security.Principal.WindowsIdentity.GetCurrent().GetUserId(); //returns nothing (null)

var userManager = HttpContext.GetOwinContext().GetUserManager<ApplicationUserManager>(); //doesn't know what OwinContext is and idk how to get to it + it doesn't know how to get to ApplicationUserManager and I also don't know where (if it even exists) that class is

var userManager = HttpContext.GetOwinContext().GetUserManager<ApplicationUserManager>(); //doesn't know what OwinContext is and idk how to get to it + it doesn't know how to get to ApplicationUserManager and I also don't know where (if it even exists) that class is

Help?

It will be injected by default into controllers and pages as

User

User

So would give you the user ID

In general, that is how you would get any claim

I have a number of useful extension methods to simplify it, for example

GetNumericId is the same it just casts into a long value, right?

I mean, you can see what it does

Identity stores the IDs as strings, by default

And since I set it to use longs for sequential IDs, I need to parse that

If your IDs are strings, keep it as-is

Angius

If they're GUIDs, you might need to parse the strings to a GUID instead of a long

yeah, I just don't understand very well what claims are or how they work

    public static long? GetNumericId(this ClaimsPrincipal principal)
    {
        var user = principal.FindFirstValue(ClaimTypes.NameIdentifier);
        var castResult = long.TryParse(user, out var userId);
        return castResult ? userId : null;
    }

    public static string? GetUsername(this ClaimsPrincipal principal)
        => principal.FindFirstValue(ClaimTypes.Name);

    public static long? GetNumericId(this ClaimsPrincipal principal)
    {
        var user = principal.FindFirstValue(ClaimTypes.NameIdentifier);
        var castResult = long.TryParse(user, out var userId);
        return castResult ? userId : null;
    }

    public static string? GetUsername(this ClaimsPrincipal principal)
        => principal.FindFirstValue(ClaimTypes.Name);
