Debugging NAV 2013 is Easy

We’ve never had a debugger quite this powerful and versatile. Debugging NAV 2013 is Easy!

By nature I am a pessimist. In any situation I tend to look for problems and point them out to everyone. Since my goal of pointing out the problems is always to SOLVE them, and leave the situation in a better state than I found it, I personally consider my natural pessimism a very positive attribute. One of the things that feeds this pessimism is previous, similar situations. One example of such a situation is the release of a new version of NAV. When this happens, the NAV developers are always hoping that the tools have improved, and for well over a decade, one especially sore point has been the debugger.

When I first started as a Navision developer, version 2.5 had just come out, and most of the customers I worked on were still on earlier versions. The debugger in those days was TERRIBLE. Even then, coming out of a job as a VBA developer, I knew that there were much better alternatives, and I was always surprised just how bad the debugging experience in Navision was. Granted, there have been significant improvements since the 2.5 days, but the worst day in NAV development history surely must have been when NAV 2009 came out, and the only way to “debug” the RTC was the workaround with the Visual Studio debugger (see this video on how to make that work). Given all of these previous experiences, let’s just say that I was realistically pessimistic for the NAV 2013 debugger, and my expectation was actually a continuation of this downward trend ;).

As I’ve said many times before, the NAV team actually cares a great deal about the development experience, and for years they had been wanting to address the development tools. They were well aware of the problems, but the priority to do anything about it was always too low to make it into a new release. With the discontinuation of all the Classic components, however, this changed and there finally was ample priority for a new debugger. The results of years of very hard work are very impressive, and in my opinion the NAV team has delivered something that is well beyond anyone’s reasonable expectations. The new debugger is a great tool, one that gives the NAV developer a lot of flexibility. Not only can we break into any type of session on any Service Tier (given the proper setup), we can even change the appearance of the debugger, and customize it to our own personal preferences.

This is another one of those things that I’ve been very anxious to share, and I am very happy that I finally had some time to put together a YouTube video and write this blog entry. Please enjoy the debugger, and I hope you are as happy with it as I am.
