The eMbedded Visual Basic focus is gradually switched to a .NET Compact Framework focus. Recently they added new demo for C# developers using their SapphireRAS component. The demo shows how to create Dial Up and Hang Up functions. Further parts and other demos in C# will be available later this year, according to the company.
