System.Data.Entity.Spatial replacement in ASP.NET Core

Question

I am trying to migrate a webform from ASP.NET MVC to ASP.NET Core MVC. Currently I am trying to find a way to replace:

using System.Data.Entity.Spatial;

With Entity Framework Core 2.2 you can use NetTopologySuite spatial library.

You can then do a query like:

var nearestCity = db.Cities
    .OrderBy(c => c.Location.Distance(currentLocation))
    .FirstOrDefault();
