I'd have to disagree with you: most people in their right mind would like to protect their investment while moving forward with new technology - it's just common sense. For VFP, this means interop.
On one hand you say it's not that hard and on the other you describe it as a nightmare. Surely there's room for improvement. If you download AVFP and you have the .NET Framework 1.1 or higher, it just runs interop, right out of the box. Some developers are too lazy to automate this stuff and they whine that it's an operational nightmare...
>Further, when you do interop you'are going to find out that the developers that have to do it, will very quickly realize that doing the same thing in pure .NET is often much easier than dealing with the operational nightmare that COM Interop is.
