Dynamics NAV 2018 and VS Code – Debugging Error, sorry that didn’t work

So you have downloaded and installed the shiny new version of Microsoft Dynamics NAV, fired up VS Code to create your first extension, run it, but then when the WebClient opens you are greeted with the blue screen and a ‘Sorry that didn’t work’ message…

Fortunately there is a quick fix, navigate to the C:\Program Files\Microsoft Dynamics NAV\110\Service folder, and edit the Microsoft.Dynamics.Nav.Server.exe.config file (you need to edit it with Administrator rights), find and remove the following line;

<NetFx40_LegacySecurityPolici enabled=”true”/>

Restart the NST and viola 🙂
