UniObjects for .NET is free and part of the UniData Client CD. U2.NET is a paid product that BluFinity MV.NET is actually repackaged and sold under the name IBM.
U2.NET has many more features than UniObjects for .NET. UniObjects for .NET is basically the main UniData API in .NET ... opens a file (table), dynamic arrays, read / write / delete records, OCONV / ICONV, subroutine calls, EXECUTE, etc.
U2.NET takes over the core that UniObjects ships and extends to simplify access to the functions DataSets and Class, SISS and other .NET.
