Why not use this method to avoid to search that record directly?

I code the EF core with MVC project in this tutorial &quot;https:&#x2F;&#x2F;learn.microsoft.com&#x2F;en-us&#x2F;aspnet&#x2F;core&#x2F;data&#x2F;ef-mvc&#x2F;crud? View=aspnetcore-8.0#the-create-and-attach-approach-to-httppost-delete&quot;<p>The example code has a search for the delete one to DB. And this method has not searching steps, I can&#x27;t agree with this way more. So why not use the best way with no searching step s directly in learning article?
