I've inherited a piece of .Net legacy code that was originally targeted for the x86 platform (32 bit). It is referencing IBM.XMS.DLL version 2.0.50727. I've updated the project to Any CPU and it builds and compiles successful. Is that version DLL (IBM.XMS) compatible with 64bit (Win 2K16) systems? Or do I have to download a newer version, if so, which version is recommended? This code is a few years old and I am not the original author so any guidance would be appreciated.
