Dynamics 365 Business Central: How to get all dependent packages (dependencies Setting) for the extension

Hi, Readers.
Today I would like to talk about how to get all dependent packages for the extension.
As you might know, when we develop for Business Central, we need to download the symbol files first. These contain the source code of the standard functions.

But if we want to extend other extensions, the default symbol files will not meet our needs. We need to add dependencies settings in the app.json file. For example,

After running the Download symbols command again, you can download their app files.

More details: App.json file

PS: How to get field values from other extensions/apps in Business Central without adding dependencies property

The same goes for standard apps, such as “SAF-T”.

So can we get dependencies setting from the code? For example, I want to check what extensions an installed extension depends on within BC. Yes, we can combine the following two methods to get the result.

• NavApp.GetModuleInfo(Guid, var ModuleInfo) Method: Gets information about the specified AL application.
• ModuleInfo.Dependencies() Method: Gets the collection of application dependencies.

Let’s see more details.
First of all, Extension Management page cannot be extended, so we need to create a new page that displays all extensions.

The application object or method ‘Extension Management’ has scope ‘OnPrem’ and cannot be used for ‘Cloud’ development. AL AL0296

We can use table 2000000153 “NAV App Installed App”:

For example,

Then add a action to get the dependencies of the selected extension.

Another example:

Great.

Very simple, give it a try!!!😁
