In trying to track down any possible reason for failures with my .EXE/.DLL Windows CE / Compact Framework pair (delineated here [What is wrong with this HttpWebRequest/HttpWebResponse code (why is it considered a "bad" request (400))?), I found this setting selected for Deployment Device
(Windows CE .NET Emulator (Default) is what is selected)
Would it be better / make any difference if I chose "Windows CE .NET Device" instead?
This seems to make more sense, as I don't use an emulator - I copy the .exe I build in XP Mode / Visual Studio 2003 to the handheld device and run it directly from there.
