How's x64 emulation going on Windows on ARM these days? Last time I looked it was garbage.

Yes, I was wondering the same thing David. I can’t recall the last time I worked on a 32 bit machine.

Do you actually support/ship your app to run on x86-only or ARM environments? If not, it probably doesn’t matter and I would probably give this one and save the battles for other things.

Folks, one of my colleagues insists on compiling everything as platform x64 mainly because he thinks "it's an x64 world and it creates a better impression". For a year I've tried to convince him that for managed code that it's a complete waste of time. I've told him that ildasm.exe shows that for x64 and AnyCPU the generated IL and the manifests are identical, I even told him that dumpbin.exe shows the only non trivial difference in the PE headers is a couple of flags that show x86/x64 and PE32/PE32+, but they don't affect the loading and running of a PE containing IL and metadata.

 

Does anyone have paradigm-shattering evidence I can give my colleague to break his habit? (I'm hoping I'm right of course!!)

 

Greg
