Good books on NAV Development

Now that the summer is over, it’s time to read a good book. Here are a couple of recommendations on the subject of NAV development.


This is one of the best no-nonsense books on NAV development you can get. Read it, understand it, and you’re ready to development with Dynamics NAV 2015. Dave has been using NAV since it was called Navision and Navigator – he knows the pedigree of the system and its history.

The book takes you through all the normal aspects of developing a customer solution with NAV – and uses best practice and sound patterns in all the solutions suggested.

Each chapter concludes with a small questionnaire that covers the content of chapter.

This book is one of the essentials for every NAV developer – I recommend it highly !

So now you can develop in NAV, then it becomes important to do it correctly.  And one way is to use design patterns. My good friend Mark Brummel is preaching about them every chance he gets, and with good reason, reusing the way NAV is already working is one of the most important paths to a successful project.

Pick up his new book in October on Design Patterns – I know I will.


And Marks old book on NAV application design is still a good source of knowledge, don’t let the “2013” title fool you, its still very relevant for 2015 (and 2016).


Introducing Erik’s ClientUserSettings.config Editor

One of the things that Microsoft has chosen to hide well is the configuration of the role tailored client. There is a file called ClientUserSettings.config that is hidden away on your PC. This file controls how the client connects to the service tier. Most of the times you don’t need to change anything in the file, but sometimes it is needed.

If you are a NAV developer it can happen quite often of you got installations with different authentication styles or other settings.

The file is located under AppData, a hidden folder, under your user account.

I got tired of searching and editing this file, so I created a small utility that would help me, introducing Erik’s ClientUserSettings Editor.

Simply run this program, it will search your PC for all .config files (in case your got more than one version of NAV installed)


It will show all parameters in the file with values in the right column.


If you got more than one config file on your PC, select the correct on from the combo box in the top.


And as an extra little bonus, I’ve added the help text from Microsoft’s website to each field, so when editing, you’ll get a helping tooltip presented.

As soon as you have enter a value in a field the file is saved and ready to use.
