# Deprecation: #94414 - LanguageService container entry

See [forge#94414](https://forge.typo3.org/issues/94414)

## Description

Instances of `\TYPO3\CMS\Core\Localization\LanguageService` require
custom initialization with a language key and additionally depend on Core services.
`\TYPO3\CMS\Core\Localization\LanguageServiceFactory` has therefore
previously been introduced in order to manage this initialization.
This replaced prior used instantiation via
`TYPO3\CMS\Core\Localization\LanguageService::create()` or
`GeneralUtility::makeInstance(LanguageService::class)`.

## Impact

Injecting `\TYPO3\CMS\Core\Localization\LanguageService` or creating
instances via `GeneralUtility::makeInstance(LanguageService::class)`,
`LanguageService::create()`, `LanguageService::createFromUserPreferences()`
or `LanguageService::createFromSiteLanguage()` will trigger a
PHP `E_USER_DEPRECATED` error.

## Affected Installations

Extensions injecting `\TYPO3\CMS\Core\Localization\LanguageService`
or creating custom instances via `GeneralUtility::makeInstance(LanguageService::class)`
or `TYPO3\CMS\Core\Localization\LanguageService::create()`.

This is relatively unlikely since most usages are bootstrap related and
extensions usually access the prepared LanguageService via `GLOBALS['LANG']`
in normal cases.

Usages of `LanguageService::create()`, `LanguageService::createFromUserPreferences()`
and `LanguageService::createFromSiteLanguage()` are be found by the extension scanner
as strong match.

## Migration

The factory `\TYPO3\CMS\Core\Localization\LanguageServiceFactory`
should be injected and used instead.
