First Release

[Tool] Auto Translation Generator for C# projects – extract & translate GetTranslation strings into 90+ languages
Version License

Hi everyone, I needed a tool that could extract all the strings to translate from the C# files and create the appropriate language files. I developed a small Windows tool that automatically extracts all GetTranslation("...") keys from any C# project (WinForms, WPF, etc.) and translates them into 95+ languages using Google Translate (free API). It then generates the corresponding .lng files ready to be used in your application.

🚀 Features

Scans recursively all .cs files in the selected project folder.
Finds every string inside GetTranslation("...") – custom regex can be adapted.
Uses Google Translate (free) to translate each string into all supported languages.
Persistent cache: avoids re-translating the same text multiple times (saves time and bandwidth).
Option to choose output folder; otherwise creates a "languages" subfolder inside the project.
GUI with real-time log, progress bar, Start/Stop buttons.
Preserves existing translations in .lng files (only adds new keys).
Removes obsolete keys (keys no longer in the code) – optional but recommended.

⚙️ How to use
Download the attached .exe (or compile from source – see GitHub link).
Run the executable (no installation required).
Select the root folder of your C# project (the one containing all .cs files).
(Optional) Choose a custom output folder for the .lng files.
Click "Start Translation".
Wait – first run may take a while depending on the number of keys and languages (cache speeds up subsequent runs).
Find all your .lng files in the output folder, ready to be embedded or distributed.

📁 Output format
Each language gets its own file, named according to the language (e.g. Italiano.lng, Deutsch.lng, English.lng). The format is:

Changelog – Version 1.1

English
New Features:
Language selection dialog – Choose which languages to translate instead of processing all 95+ every time. "Select Languages" button – Opens a checklist with all available languages (Select All / Unselect All buttons included). Performance improvement – Translation time now proportional to the number of selected languages (much faster when only a few needed). Changes:

Removed hardcoded full language list from main form; now managed via selector. Improved cache handling – cache remains valid across different language selections. Bug fixes:

Fixed occasional UI freeze during long operations. Better error handling for network timeouts. Credits: Lululla © 2026 – Support: linuxsat-support.com
