Entity Framework Core - EF Core 2.2 - 'Point.Boundary' is of an interface type ('IGeometry')

Question

I am trying the new functionality with EF Core 2.2. It is based on the following article. \"Announcing Entity Framework Core 2.2\" https://blogs.msdn.microsoft.com/dotnet/20

You need to call UseNetTopologySuite(). Example here:

public class ApplicationDbContext : IdentityDbContext
{
    public ApplicationDbContext(DbContextOptions options)
        : base(options)
    {

    }

    protected override void OnConfiguring(DbContextOptionsBuilder optionsBuilder)
    {
        IConfigurationRoot configuration = new ConfigurationBuilder()
           .SetBasePath(Directory.GetCurrentDirectory())
           .AddJsonFile("appsettings.json")
           .Build();
        var connectionString = configuration.GetConnectionString("DefaultConnection");
        optionsBuilder.UseSqlServer(connectionString, opts => opts.UseNetTopologySuite());
    }
    public DbSet Tests { get; set; }
}


public class Test
{
    public int Id { get; set; }
    public Point Location { get; set; }
}

I ran into this problem because I had a if (!optionsBuilder.IsConfigured) around everything in my OnConfiguring. I had to remove this in order to get add-migrations to work.
