    This article will explore the difference between x86 and x64 when it comes down to the .NET framework.

    Will you still write me, will you still compile me, when I'm sixty-four (bits)?

        They are doing it gradually. I don't know of anyone who has made Windows 1.0 work on a modern x64 chip. I managed to get Windows 2.1 "sort of" get up and running - but my CPU is a 5th generation i7-5820, and most applications, even old ones, failed. I guess Windows 3.x will be next to go, then Windows 95 and Windows 98. Maybe even XP. When all of those fail to run on modern CPUs, it is time to drop x86 support. For IoT devices, we can run a 386 VM under Windows 11 on that IoT chip. Some CP members are extremely good at handling IoT chips; I am sure they can handle this as well. I was programming IoT software on an eight bit 8051 CPU less than ten years ago, but the chips were sold for several years after that (with no software updates). Today, the 8-bit chips are not visible in the marketing, but I wouldn't be surprised if old customer can still have them delivered.
