Create asset bundle on backend - using Unity namespace in backend app

Hello!

I am going to give possibility for user to upload content (some 3d model) from web CMS and then, in Mobile App created with Unity - download it and show for user. Please tell me - is there a possibility to include Unity namespace into some Mono .Net Web App (for example MVC?). What I would like to achieve is build an Asset Bundle package on server. Thank you in advance for answers!
