Visual Basic Upgrade Companion

Visual Basic Upgrade Companion (VBUC) is a VB 6.0 to C# or VB.NET migration tool that accelerates the code conversion process. This advanced tool provides a cost-effective solution that features ADO to ADO.NET conversion, variable type resolution ("late binding" problem), error handling replacement, use of .NET native libraries, code refactoring, third party component mappings, migration of mixed VB6 and ASP projects, multi-project upgrade support, and much more. VBUC reduces the amount of manual coding and generates a native .NET application that is equivalent to the original VB6 system.

It simplified the conversion and helped keep our time to market in line with our goals, while allowing savings of about 80%.
