About the technology
Development for ERP Systems
X++ is the primary object-oriented programming language used to customize and extend Microsoft Dynamics 365 for Finance and Operations and its predecessor, Microsoft Dynamics AX. It enables organizations to model complex business processes, manage database queries directly within the code, and handle enterprise-level transactions.
The Microsoft Dynamics Ecosystem
The development environment relies heavily on Visual Studio, where specialists write X++ code, manage metadata, and build packages. The architecture integrates tightly with SQL Server, Azure services, and the Power Platform, requiring experts to understand both ERP logic and cloud infrastructure.
Typical Project Deliverables
Specialists working with this language handle deep customizations of standard ERP modules to fit unique business needs.
- Customization of standard data models and table extensions
- Creation of custom data entities for OData and batch integrations
- Development of complex SSRS reports and business documents
- Implementation of custom event handlers and chain of command extension patterns
Dusseldorf Enterprise Context
Many industrial, logistics, and retail businesses in the Dusseldorf region rely on Microsoft ERP systems to run their global operations. Local companies frequently hire external specialists to bridge the gap between standard software capabilities and German accounting, tax, or supply chain requirements.
Indicators for External Support
Organizations often seek freelance experts during critical phases of their enterprise software lifecycle.
- Migrating legacy Dynamics AX installations to cloud-based Dynamics 365
- Experiencing performance bottlenecks during database operations or batch runs
- Lacking in-house capacity for large-scale functional customizations
- Needing specialized integration with external third-party logistics systems
Qualities of Top Professionals
Strong specialists possess deep knowledge of the Application Object Tree, data dictionary structures, and the MorphX framework. They write clean, performant code that respects ERP best practices, preventing upgrade conflicts and ensuring long-term system stability.
Frequently asked questions
Key details about X++, drawn from the questions we get asked most.
Companies use X++ to customize the business logic and data structures of Microsoft Dynamics 365 for Finance and Operations. It allows developers to create custom forms, tables, and classes that handle complex enterprise resource planning workflows.
While C# is a general-purpose language, X++ is specifically designed for ERP development with built-in SQL-like database queries. Specialists often use both, but business logic inside the Dynamics platform is best written in the native ERP language.
An X++ specialist should be proficient in SQL Server, Azure DevOps, and Visual Studio. Familiarity with the Power Platform, Power BI, and integration technologies like OData or dual-write is also highly valuable.
Yes, most X++ development and configuration can be handled remotely. However, local companies in Dusseldorf often prefer hybrid arrangements during initial system analysis or critical go-live phases to facilitate direct communication with key business users.
Look for experience with the Chain of Command pattern and extension-based customization models in Dynamics 365. A qualified specialist writes code that does not block standard Microsoft updates and understands database indexing for optimal performance.
Yes, migrating legacy Dynamics AX systems to the cloud requires a rewrite of older code into modern extension patterns. Experts in this language are essential for refactoring code and mapping legacy data to the new Dynamics 365 schema.
