In my last article about .NET platform called "Microsoft .NET Common Language Runtime Overview" I introduced technologies that .NET Framework Beta2 provides us. I also showed infector for .NET applications written in C# (called "Donut" by AVerz). Very soon after publishing Microsoft released sharp version of Visual Studio .NET. Since that time nothing changed at all, this version does not differ from the beta2 much. But I had more time, documentation and knowledge to explore this environment.
