+Fetch via interfaces
+~~~~~~~~~~~~~~~~~~~~
+
+Suppose your ``Product`` object implements an interface called ``ProductInterface``.
+If you want to decouple your controllers from your entity implementations, you can instead reference entities via an interface.
+To do this, first you need to configure the :doc:`resolve_target_entities option </doctrine/resolve_target_entity>`.
+        
+Your controller can then reference the Product entity by its interface instead::
+
+        public function show(
+            #[MapEntity]
+            ProductInterface $product

+
+    Support for ``resolve_target_entites`` in the ``EntityValueResolver`` was introduced in Symfony 7.3.
