You must have heard about the Dynamics NAV Design Patterns initiative already. It has been mentioned numerous times on conferences and on blogs.
Recently, I was happy to work together with the team on what is in my opinion one of the most important Microsoft Dynamics NAV Design Patterns, what we call “Reusable Bugs“.
It is really a catchy title ..but above all, a must-read, because it is so valuable for you, being a NAV developer that cares .. and that wants to do a decent job.
You can read all about it on the team blog, here: http://blogs.msdn.com/b/nav/archive/2015/04/01/reusable-bugs.aspx
