How to use a separate project with ASP.NET.CORE Identity in the main project with a three-layer architecture?

Question

PHP

I want to use a separate project for authorization instead of implementing Identity in a three-layer (because I don’t know how to do it)
, but how can I use it in the main application?
Do you need your own database for this?
What then to do with migrations?
Are there any guides or solutions?

Answer 1

I decided!

$products = $db->query("SELECT name, description, pricerub, priceusd FROM products");
    	$product = '';
    while ($row = $products->fetch_array()) {
      $product .= $row['name']." (".$row['description'].") — ".$row['pricerub']."₽"." (".$row['priceusd']."$)\n";
    }
    $bot->sendMessage($chat_id,
'Товары:
'.$product.
'

Введите стоимость товара который хотите купить');

Answer 2

There are no elements in the $product array with indexes 'name' or 'pricerub'.
Either form the array correctly initially, or use array_column().
