AL, X++ and .NET Development
Dynamics 365 Custom Development Services
Business Central AL development, X++ development for Finance and Operations, and .NET plugin and PCF development for Dynamics 365 Customer Engagement. Every extension is upgrade-safe and tested against each Microsoft release wave, so your customizations survive every spring and fall update without a rebuild.
Dynamics 365 development services from a Microsoft Solutions Partner for organizations in the USA, the UK, the Nordics, and the Middle East.
When Custom Development Is the Answer
Configure First
Most Dynamics 365 requirements can be met without writing a single line of code. A partner who defaults to custom development for every requirement is either unfamiliar with the platform or not putting your budget first.
- 01No code
Configuration First
Standard Dynamics 365 customization through configuration covers most business requirements. Workflows, business rules, views, forms, and dashboards are configured without touching code. If configuration meets your requirement, that is the recommendation.
Not enough? Next step - 02Pre-built
AppSource Extensions Second
Microsoft AppSource has thousands of pre-built extensions for Business Central and Dynamics 365. If a validated marketplace app meets your requirement, buying it costs less and adds no custom code risk.
Not enough? Next step - 03Custom code
Custom Development When Necessary
Custom code is reserved for requirements that configuration or an existing app genuinely cannot meet. When it is the right answer, Dynamics 360 delivers it through extension based development on official APIs, with no direct object modification.

The Right Language for Each Product
AL, X++ and .NET
AL, X++ and .NET each map to one Dynamics 365 product and one architecture. Using the wrong one creates upgrade risk and maintenance cost.

}Business Central Development Services (AL)
AL is the extension language for Business Central. Our AL development services deliver per-tenant extensions that run on top of the standard platform without modifying base objects, versioned in Azure DevOps and released through CI/CD pipelines.

What Upgrade-Safe Actually Means
Upgrade-Safe
"Upgrade-safe" is the most overused phrase in Dynamics 365 extension development. Every partner claims it. Here is what it means in practice.
Your extensionsMicrosoft platform
Wave 1, 2026AprilTested
Wave 2, 2026OctoberTested
Wave 1, 2027AprilTested
Wave 2, 2027OctoberTested
Extension Only, No Object Modification
Standard objects, tables and code are never changed. Every customization is a separate extension layer, so when Microsoft pushes an update, your extensions sit above it untouched.
Tested Against Each Release Wave
Microsoft ships two major updates to Business Central and Finance and Operations every year. Release wave testing for Business Central and Finance and Operations checks every extension against the current release and the next one before it reaches your environment.
Versioned and Documented
Every extension is version controlled, documented and deployed through application lifecycle management in Azure DevOps. Upgrade safe extensions need clean codebases, not just clean architecture, so any developer can pick them up.
No Dependency on Unsupported APIs
Only Microsoft's official, supported APIs. No undocumented calls, no direct database access, no workarounds that break on the next update.
How We Deliver Custom Development
Delivery Process
Six stages, with a gate at design sign-off, code review and release testing.
- 01
Requirements and Technical Design
We confirm whether configuration, a pre-built app or custom code fits best, and complete the technical design before development begins.
- 02Gate: your sign-off
Extension Architecture
Designed around your environment, release schedule and integration dependencies. You sign off before development starts.
- 03Gate: code review
Development and Code Review
Sprint-by-sprint development with a code review every sprint, against official APIs and Microsoft AL or X++ guidelines, version controlled in Azure DevOps.
- 04Gate: release test
Release Wave Testing
Every extension is tested on the current release and validated for the next before production deployment.
- 05
Deployment and Handoff
Deployed through test and production with full documentation, and ready to hand to your internal team or another partner.
- 06
Post-Deployment Support
A Hypercare period after every deployment. Post-release issues are resolved before the engagement closes.

DenmarkDynamics 365 Custom Development FAQs
Common Questions
Straight answers before you book a call.
Yes, when it is developed correctly. Extension-only AL and X++ code on official Microsoft APIs, with no object modification, survives every platform release. Dynamics 360 tests every extension against the current release and the next update before it reaches your environment.
AL is the extension language for Business Central. X++ is the development language for Finance and Operations. They serve different products, follow different patterns and need different skills. Dynamics 360 has a certified Business Central AL developer team and X++ developers.
Yes. Microsoft's standard Business Central agents cover common jobs. Dynamics 360 develops custom agents and Copilot extensions for the processes they do not cover, such as supplier confirmations and purchase order handling, with human approval on every critical action.
It depends on the product, the number and complexity of extensions, integrations and testing scope. Dynamics 360 gives you an estimate after the requirements and technical design stage, before development begins.
You do. Extensions, source code in Azure DevOps and documentation are handed over at the end of the engagement, so your team or another partner can maintain them.
Yes. Every takeover starts with a code audit of architecture, API usage, upgrade risk and documentation before any new development begins.
Yes. Dynamics 360 delivers AppSource app development: multi-tenant AL and X++ extensions designed for Microsoft's technical validation, for ISVs targeting the Business Central and Finance and Operations marketplaces.

Yes. Server-side plugins, custom workflow activities, PCF controls and .NET integrations across Dynamics 365 Customer Engagement, including Sales, Customer Service and Field Service.
C/AL was the development language of Dynamics NAV and older Business Central versions. Moving to the latest cloud version means rewriting C/AL customizations as AL extensions. Dynamics 360 assesses, rewrites and validates the code as part of the NAV to Business Central migration.
