Associating a Standard Controller with a Visualforce Page
To associate a standard controller with a Visualforce page, use the standardController attribute on the <apex:page> tag and assign it the name of any Salesforce object that can be queried using the Lightning Platform API.
For example, to associate a page with the standard controller for a custom object named MyCustomObject, use the following markup:
<apex:page standardController="MyCustomObject__c">
</apex:page>
