How to publish App in Business Central without PowerShell ?

While publishing the app I was getting 2 issues :-

Issue 1 :

It was not getting updated and nothing was happening in Output Window. I had installed it via 

PowerShell and it was working for me fine. But there was a problem we need to install several 

versions of same APP. And it was a very lengthy process.

Issue 2 :

While publishing it was giving me error 

MSDYN365BC - Publish Extension Error - NetFx40_LegacySecurityPolicy is enabled and must be turned off.

Solution:

Step 1 :

Go to this file in Service Folder as Shown in Screenshot. (Remember you need to run your system as administrator)

Step 2. Open File in Notepad and find Runtime and make the property to false as shown.

Step 3. Now Restart your NAV Service and Come to visual studio code in your project.

Press F5 or goto View -> Command Pallete -> AL:Publish

Your extension must be published.

If still its not publishing you can comment below.
