# Breaking: #61821 - classFile option in makeInstanceService removed

See [forge#61821](https://forge.typo3.org/issues/61821)

## Description

The option "classFile" in `TYPO3CMSCoreUtilityGeneralUtilitymakeInstanceService()` is removed.
This should now be done by the respective ext_autoload.php of each extension.

## Impact

Extension classes relying on the "classFile" registration for autoloading will not be loaded anymore.

## Affected installations

A TYPO3 instance is affected if a 3rd party extension uses the removed class loading registration method.

## Migration

Use the ext_autoload.php file to autoload the class.
