How to make use of all available languages in tesseract?

I'd like to create a simple WPF program for OCR scanning with tesseract in which the user can choose the language/s to scan with.² Now for some reason tesseract expects there to be a tessdata folder with the language files directly in it instead of the language subfolders.

using (var engine = new TesseractEngine(@"./tessdata", "deu", EngineMode.Default))

doesn't work if the deu files aren't located directly in the tessdata folder - neither does it work when using @"./tessdata/deu".

It only works when having the language file located directly in the tessdata folder (also in the project-structure).

How to properly make use of all available languages?

²Actually, if possible later on I'd like to auto-detect the language in images - e.g. by scanning each image with each language and checking which language had the best result. If you have any idea on how this could be done please let me know.

you should create a tessdata directory in debug folder of your project and put the language files there .
