Try with below solutions, Replace _ with folder and separate each folder path like below,

<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:ObjectManager/etc/config.xsd">
   <preference for="Magento\Catalog\Block\Product\View" type="Magento\Module\Inject\Session\Block\Product\View"/>
</config>

Set your block php file at below location,

app/code/Magento/Module/Inject/Session/Block/Product/View.php

inside php file,

<?php
namespace  Magento\Module\Inject\Session\Block\Product;

class View extends \Magento\Catalog\Block\Product\View{

    //your custom code.....

}
