Was Dynamics AX Originally a Microsoft Product?

Top of Page

No, Dynamics AX was not originally developed by Microsoft. It was first developed by a Danish company called Damgaard Data and was known as Axapta. Axapta was launched in 1998 as an ERP solution, primarily targeting large and medium-sized businesses.

In 2000, Damgaard merged with Navision Software A/S, another Danish software company known for its ERP solution, Navision (which eventually became Dynamics NAV and then Dynamics 365 Business Central). This merged entity, NavisionDamgaard, was then acquired by Microsoft in 2002. After the acquisition, Axapta became part of Microsoft’s ERP product line and was rebranded as Microsoft Dynamics AX in 2006.

Microsoft continued to develop and enhance Dynamics AX, ultimately evolving it into what is now known as Dynamics 365 Finance and Dynamics 365 Supply Chain Management as part of the Dynamics 365 suite.

Were NAV and Axapta .Net Products?

Top of Page

No, Dynamics NAV and Axapta (Dynamics AX) were not originally built on the .NET framework. They were developed before .NET became widely available.

Dynamics NAV (formerly Navision)

• Language and Environment: Dynamics NAV was originally built using a proprietary language called C/AL (Client/Server Application Language) and ran on the C/SIDE (Client/Server Integrated Development Environment).
• Transition to .NET: When Microsoft acquired Navision, it began integrating .NET features into the product. However, full .NET support only came gradually, with more significant integration in later versions. Eventually, in Dynamics 365 Business Central, which is the cloud-based evolution of NAV, there is extensive .NET interoperability, though the AL language (an evolution of C/AL) is still used.

Dynamics AX (formerly Axapta)

• Language and Environment: Dynamics AX was initially developed in X++, an object-oriented language similar to C++ and Java, specifically designed for ERP tasks in AX.
• Transition to .NET: After Microsoft acquired Axapta, the company worked to align it with the .NET ecosystem. Starting with Dynamics AX 4.0 in 2006, Microsoft introduced .NET interoperability, allowing AX to work with .NET classes and libraries. By the time of Dynamics AX 2012, there was even closer integration with .NET, though X++ remained the core language for customizations. Dynamics 365 Finance and Dynamics 365 Supply Chain Management, as cloud-based successors of AX, are fully built on the .NET framework and run on Azure, using modern technologies and extensive .NET support.

In summary, NAV and Axapta were not originally .NET products, but over time, both were gradually integrated with .NET to varying extents, especially after Microsoft’s acquisition. Today, their cloud-based successors—Dynamics 365 Business Central and Dynamics 365 Finance—are much more integrated into the .NET ecosystem.

What Was the Programming Path from X++ to 365 Online?

Top of Page

The transition of X++ from its origins in Dynamics AX to its modern implementation in Dynamics 365 Finance and Supply Chain Management (the cloud-based successors of AX) involved several stages, evolving from a proprietary ERP-focused language to a more .NET-integrated framework for cloud-based environments. Here’s an overview of the programming path:

1. Origins of X++ in Axapta

• Initial Language: X++ was developed as an object-oriented language for Axapta (later Dynamics AX) to support ERP functions, specifically for large-scale financial and operational tasks.
• Features: It combined the syntax of Java/C++ with SQL-like database querying abilities, making it highly suited for data-heavy ERP applications.
• Environment: It operated within the MorphX development environment, which included tools for form building, report generation, and debugging.

2. Introduction of .NET Interoperability in Dynamics AX 4.0 (2006)

• Microsoft Acquisition Influence: After Microsoft acquired Axapta, the company began aligning AX with its broader product ecosystem, which included the .NET framework.
• Initial .NET Integration: AX 4.0 introduced basic .NET interoperability, enabling X++ code to interact with .NET classes, allowing developers to expand functionality by leveraging .NET libraries while still writing most core code in X++.

3. Enhanced .NET Integration in Dynamics AX 2012

• Greater .NET Support: Dynamics AX 2012 significantly enhanced .NET interoperability. It allowed X++ to call .NET assemblies directly and vice versa, creating smoother integration for developing solutions that required .NET functionality.
• Visual Studio Integration: Although MorphX was still the primary development environment, AX 2012 introduced more Visual Studio integration, which allowed developers to work with .NET classes alongside X++.

4. Transition to Dynamics 365 and Cloud Platform

• Shift to Azure and Cloud-First Model: With the launch of Dynamics 365 Finance and Dynamics 365 Supply Chain Management, AX evolved into a fully cloud-based model, hosted on Microsoft Azure.
• Enhanced Visual Studio Integration: Visual Studio became the primary development environment, and MorphX was retired. This shift encouraged developers to use Visual Studio’s advanced tools and streamlined development process.
• Compiler and Runtime Changes: X++ was re-engineered to run in the .NET Common Language Runtime (CLR), allowing it to leverage more features of .NET, including memory management, garbage collection, and enhanced performance.

5. Modern X++ in Dynamics 365 (Online)

• Core Language Remains X++: Although X++ is still the primary language for customization, the modern version is compiled in the .NET CLR, bringing it closer to .NET standards.
• Cloud-Centric Development: Customizations and extensions are now designed as packages in Visual Studio and managed through Azure DevOps for continuous integration and deployment (CI/CD) in the cloud.
• Extension-Only Model: Dynamics 365 uses an “extensions-only” model, meaning customizations are done through extensions rather than direct modifications to the core code. This prevents disruption to the core system during updates and makes cloud deployment smoother.
• API and Data Entities: Dynamics 365 introduced standardized APIs and data entities, which developers use for data exchange and system integration, aligning more closely with .NET and Azure data frameworks.

6. Current Capabilities in the Dynamics 365 Ecosystem

• Power Platform Integration: Dynamics 365 Finance and Supply Chain Management integrate closely with the Microsoft Power Platform, enabling developers to use Power Apps, Power Automate, and Power BI for low-code/no-code solutions.
• Modern DevOps and Lifecycle Services (LCS): Dynamics 365 supports modern DevOps practices via Azure DevOps, along with lifecycle management tools in Microsoft’s Lifecycle Services (LCS) for managing development, deployment, and monitoring in a cloud environment.

Summary of the Transition Path

• Legacy: X++ originated as a proprietary ERP language in Axapta, operating in MorphX.
• Early .NET Interoperability: With Dynamics AX 4.0 and AX 2012, X++ gained some .NET interoperability and Visual Studio integration.
• Cloud and .NET Alignment: Dynamics 365 Finance and Supply Chain Management brought full cloud deployment, integration with .NET CLR, and Visual Studio as the primary development tool.
• Modern Cloud-First Development: Today, X++ in Dynamics 365 focuses on extensions, CI/CD in Azure, and robust .NET and Power Platform integration for a seamless cloud ERP experience.

This journey represents the evolution of X++ from a standalone ERP language to one embedded in Microsoft’s cloud-first and .NET-driven architecture, enabling modern, scalable solutions for large enterprises.

Working with a Microsoft partner can help manage the complexities of the migration, ensuring data integrity, process realignment, and minimal disruption to your business.

Why not Make Dynamics Totally Modular and Drop AX/NAV Borders?

Top of Page

Microsoft chose to keep Dynamics 365 Finance (formerly AX) and Dynamics 365 Business Central (formerly NAV) as distinct products rather than fully modularizing and merging them, largely due to their different target audiences, functional scopes, and underlying architectures. Here are some reasons why Microsoft maintained these distinctions:

1. Different Target Markets and Complexity Levels

• Dynamics 365 Business Central is designed for small to medium-sized businesses (SMBs), prioritizing ease of use, simpler setup, and affordability. It covers essential ERP needs in a streamlined way, making it more accessible and cost-effective for smaller businesses.
• Dynamics 365 Finance and Supply Chain Management targets larger enterprises with more complex, often global, operational requirements. It includes advanced features and modules tailored for large-scale financials, manufacturing, and supply chain needs, which smaller businesses may find overwhelming and unnecessary.

By keeping these products distinct, Microsoft can better cater to the needs and budgets of both SMBs and large enterprises without forcing smaller businesses to pay for or manage functionality they don’t need.

2. Varying Functional Depth

• Finance and Supply Chain Management offers a higher degree of depth in areas like global financial management, multi-company operations, advanced manufacturing, and supply chain logistics that are not needed by most SMBs.
• Business Central, while modular, provides a more generalist approach with streamlined functionality that is adequate for smaller organizations without the same level of complexity.

Creating a single modular system that accommodates these varying functional depths could risk either under-serving large enterprises or over-complicating the experience for SMBs.

3. Distinct Development Histories and Architectures

• Dynamics AX and Dynamics NAV were developed independently by different companies with different programming languages, architectures, and development ecosystems. AX used X++ and a different data model, while NAV used C/AL (later AL) and the C/SIDE environment. These architectural differences made it challenging to merge them seamlessly.
• When Microsoft transitioned to the Dynamics 365 suite, they modernized and adapted each product for the cloud but retained these architectural foundations. Fully merging AX and NAV would have required rewriting large parts of both systems, which would be costly, time-consuming, and disruptive to existing customers.

4. Modularity Challenges in ERP Systems

• While modularity is valuable, achieving it in ERP systems is challenging because many modules (like finance, inventory, and HR) are interdependent. A fully modular ERP with swappable modules at every level could create integration, data consistency, and performance issues, especially in complex business environments.
• Instead, Microsoft has implemented modularity in more specific areas, allowing customers to add applications like Dynamics 365 Sales, Marketing, and Customer Service across both platforms. For ERP-specific functionality, though, some foundational modules need to be tightly integrated.

5. Product and Platform Flexibility

• By keeping Business Central and Finance as distinct offerings, Microsoft allows customers to scale with flexibility. SMBs can start with Business Central and then, if they outgrow its capabilities, migrate to Finance.
• Meanwhile, the modular Dynamics 365 ecosystem still enables businesses to pick and choose applications outside of ERP. For example, both Business Central and Finance can integrate seamlessly with other Dynamics 365 apps, Microsoft 365, and Power Platform solutions.

6. Licensing and Pricing Structure

• Microsoft’s pricing model is designed to suit different business sizes and complexities. Business Central has a simpler, more affordable licensing structure that fits SMB budgets. Finance, on the other hand, has a more complex pricing model, suitable for enterprises with more specific needs.
• By keeping them separate, Microsoft avoids creating a one-size-fits-all product that may be too expensive for SMBs or too limited for large enterprises.

7. Minimizing Disruption for Existing Users

• Both AX and NAV had large, dedicated user bases with extensive customizations tailored to each platform. Forcing a migration to a single modular platform would have disrupted these businesses significantly, as their existing processes, customizations, and data structures would have required extensive rework.
• By evolving both systems within the Dynamics 365 ecosystem, Microsoft allowed users to upgrade without a complete overhaul.

Conclusion

The decision to keep Dynamics 365 Business Central and Dynamics 365 Finance as distinct offerings allows Microsoft to serve a broader range of businesses with tailored solutions that match their scale and complexity. By maintaining this dual-path approach, Microsoft strikes a balance between modularity and specialization, enabling businesses to choose an ERP solution that fits their unique needs while still benefiting from the broader Dynamics 365 ecosystem.
