If C# was only >2% slower than natively compiled C/C++, I'd kiss C/C++ goodbye (I'm not holding >my breath though). The thing I most liked about C# was Windows Forms. It is much easier to create a graphical user interface using Windows Forms than using MFC (especially its awkward Document/View). But it seems that MSVC .NET 2003 has added support for Windows Forms in C++, which means that you can take benefit of easier GUI creation in C++. I haven't tried it yet, but it seems to be the case: Programming Windows Forms with Managed Extensions for C++ http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dv_vstechart/html/vctchWindowsFormsForManagedCProgrammers.asp
