From the humble logic gate came the CPU. The CPU begat machine code, machine code begat assembler, assembler begat C, C begat the Windows API and finally the Windows API begat the .NET Framework. So to come full circle, I thought I'd implement logic gates on top of the .NET Framework.
I've implemented OR, AND, XOR and NOT gates, along with a switch for setting inputs and a light for seeing outputs. Just place the gates on the VS.NET forms designer and hook them up through their properties.
It's now 2024 and remarkably this still works in the latest version of Visual Studio. I imagine there are much better implementations of this kind of thing available but impressive backwards compatibility from Microsoft
