# Dynamics 365 Business Central on-premises: accessing embedded in-app resources from runtime packages.

[Read the post](https://demiliani.com/2025/08/27/dynamics-365-business-central-on-premises-accessing-embedded-in-app-resources-from-runtime-packages/) · Stefano Demiliani (Stefano Demiliani, MVP) · 2025-08-27 · 367 words · tier community · reviewed (checked by Opus)

> From version 25.2 (2024 Wave 2), Business Central extensions can embed resources: you declare them with resourceFolders in app.json and read them with NavApp.GetResource. On-premises runtime packages made with Get-NavAppRuntimePackage could not load embedded resources up to version 26.2, so the full package had to be published. Support arrived in 26.3 (platform 26.0.35604.0).

## Key points

- Extensions can declare resource folders using the resourceFolders property in app.json
- AL code accesses embedded resources via the NavApp.GetResource method
- Runtime packages did not support embedded resources until version 26.3 on-premises
- Partners often use runtime packages to protect intellectual property by excluding AL code
- Full extension packages were required as a workaround on versions 26.2 and earlier

## Quotes

- "Embedded resources on runtime packages are not supported in Dynamics 365 Business Central with version <= 26.2." (Clarifies the limitation that existed and caused troubleshooting issues)

## AL objects mentioned

As named in the post. A name that matches one object page by exact type and name links to it; the others stay as named.

- other "NavApp.GetResource"

## Context

- Features: Resource folders in extensions, Embedded resources support, Runtime packages, Resource access from AL code
- Versions: 2024 Wave 2, 25.2, 26.2, 26.3, 26.0.35604.0
