Thank you for your inquiry.
Currently only GroupDocs.Comparison for .NET 'MVC front-end is available, however we are also in development process of ‘WebForm’ based front-end, once we have this in our showcases, we will inform you here.
Thank you for your patience.
I am working on upgrading to the latest and we are using three of your products (Annotation, Viewer, and Compare). We are using ASP.NET webforms. Is it possible to only upgrade Annotation and Viewer?
Or what are our options for upgrades on all of these products?
