If you are working with Dynamics 365 for Financials, when it comes time to submitting your extension to AppSource, you need to supply some marketing materials, for examples walkthroughs and videos.
As the only option right now is to use the Dynamics NAV 2017 Web Client for testing (no Dynamics 365 sandbox…yet!), it can be a pain that the title ribbon in the Web Client says Dynamics NAV. When submitting to AppSource, there can be no trace of NAV in any of your marketing materials.
But with a small change to your Web Client url, you can change that title ribbon from this…
navribbon
to this…
d365ribbon
You do this by simply adding the following parameter to the end of the url:

?aid=fin

Example:

http://localhost:8080/DynamicsNAV100/WebClient/?aid=fin

That’s it! Bookmark both versions of the url to easily switch between a NAV demo and a Dynamics 365 demo!
