D365FO new custom module not showing

Problems Statement:

I had been able to create new modules by creating 'Menu' element, creating extension of 'MainMenu' menu and then referencing my custom menu there. I had deployed a new development VM with Product version Finance and Operations (10.0.5) and platform version 29, which was latest available till date (1st January 2020). I developed a new Menu the same way I used to do but it's not showing in Modules panel in left side. I built all the models and run db sync, still the problem exist.


Solution:

On my visual studio I set a display menuitem from that module as a startup project and ran with F5. It forced the module to show up.

I asked this question on community when I faced the issue first.
