How to use "shop-script" api on .NET platform?

Question

CMS

Briefly about the problem: the "webasyst" platform (shop-script v5 module) provides a set of api methods for working with data ( www.webasyst.ru/developers/docs/api/explorer/shop/). I am developing a .NET data management system using api and I have problems with the method: shop.product.images.add ( www.webasyst.ru/developers/docs/api/explorer/shop/... If anyone had experience or something that can suggest on this or a similar api or similar problem - I would be very grateful.Any useful links are also welcome!
