I have been able to download a Dynamics NAV PDF that is stamped for version 5.00. We are using NAV 2015 (version 8). I can find stuff on MSDN, but was wondering if there was an official PDF somewhere so when I'm not connected to the Internet, I can still read through the documentation.
there is nothing offline unfortunately. Everything is on MSDN for Dynamics NAV even the Application Help. You can download something "semi-offical" from here: CAL-Coding-Guidelines-at-Microsoft-Development-Center-Copenhagen.pdf But most of the guidelines are still the same since Version 5 (even the original version 2...)
Cheers!
