- Availability
- Generally available (October 2026)
- Industry focus
- Scale-up businesses (fast-growing D2C brands, tech-enabled services)
Scale-up businesses move fast. They hire contractors for a few months, bring in new developers and switch partners as they grow. If they run Business Central, they usually build at least some extensions of their own. Every hour a new developer spends setting up tools is an hour not spent building. Business Central 29.0 cuts that set-up time.
The industry challenge
A fast-growing direct-to-consumer brand might use Business Central for finance, inventory and fulfilment. It often adds extensions for marketplace integrations, subscription billing or custom reporting. Its development work is typically done by:
- One or two in-house developers
- Short-term contractors brought in for specific projects
- A partner for larger pieces of work
Each of these people needs a working AL development environment. Historically, that meant installing the right runtime, configuring the AL extension and dealing with separate sign-in prompts when connecting to Business Central. The experience could differ between Windows, macOS and Linux, and between local and browser-hosted environments.
None of that is hard for an experienced AL developer. But for a contractor or a developer coming from another platform, it's friction that delays the first useful contribution.
What Microsoft delivered in Business Central 29.0
According to Microsoft, the AL extension for Visual Studio Code now:
- Acquires the required .NET runtime automatically
- Uses Visual Studio Code authentication by default, which reduces separate sign-in prompts
- Works more consistently across Windows, macOS and Linux, and across local and browser-hosted environments
Microsoft also notes that the AL extension is smaller, because it no longer bundles a separate runtime copy for each supported operating system.
Where the value shows up
| Business area | Impact for a scale-up |
|---|---|
| Onboarding | New developers and contractors start contributing sooner |
| Contractor cost | Fewer paid hours spent on environment set-up |
| Flexibility | Developers can use the operating system they prefer |
| Remote work | Browser-hosted environments work more smoothly |
| Support burden | Fewer "my environment doesn't work" requests |
For a scale-up, speed of execution is everything. Shaving set-up time sounds minor, but it compounds across every new hire and every short contract.
A worked scenario
Consider an online homeware brand that has grown from £5 million to £30 million in revenue in four years (an illustrative example). It runs Business Central with a custom extension that connects to two marketplaces and its 3PL.
For peak season, it hires a contractor to build a new returns-processing feature. The contractor works on a Mac and has used Business Central before but not recently.
Before 29.0, the first morning would have gone on installing runtimes, configuring the extension and sorting out sign-in. With Business Central 29.0, the contractor installs the AL extension, which fetches what it needs and signs in through VS Code. By lunchtime they've downloaded symbols and started work on the returns logic.
Adoption considerations
- Update your onboarding guide. Remove steps that are no longer needed and keep the guide short.
- Standardize on supported versions. Make sure everyone uses the AL extension that matches your Business Central version.
- Review access controls. Easier sign-in is good, but make sure contractors only get access to the environments they need.
- Use sandboxes for new starters. Let new developers practise against a sandbox before touching shared environments.
- Consider browser-hosted development. For short contracts, a hosted environment can remove local set-up almost entirely.
The bottom line
Scale-ups need their systems to keep pace with their growth, and that includes the people who extend them. Simpler AL development set-up in Business Central 29.0 removes a familiar source of delay for new developers and contractors. It's a modest change that pays off every time the team grows.
If your business is building its own Business Central extensions, it's worth reviewing your development set-up and onboarding with an experienced adviser.
