Course Overview

The Development II in Microsoft Dynamics AX 2012 course by Microsoft is a specialized two-day instructor-led training designed for experienced systems consultants and application developers working at Microsoft Dynamics partners. This course prepares learners for the MB6-869 certification exam, focusing on advanced X++ programming, object-oriented development, and database integration within the Dynamics AX 2012 environment. Target roles include Dynamics AX developers, technical consultants, and customization architects responsible for implementing and extending enterprise resource planning solutions. With X++ programming recognized as a scarce and high-demand skillset, this training addresses a critical industry need—over 400 consulting and implementation firms globally continue to support Dynamics AX 2012 environments, creating sustained demand for certified professionals.

Students engage with core Microsoft development tools including MorphX, Application Object Tree (AOT), Visual Studio 2010 with Application Explorer, and the Reverse Engineering tool within the Dynamics AX 2012 lab environment. The hands-on labs emphasize real-world development tasks such as building data manipulation classes, creating secure APIs using Code Access Security, and implementing exception handling with Try, Catch, and Retry statements. A key project involves developing a full CRUD (Create, Read, Update, Delete) module that interacts with the CustTable via X++ select statements and kernel-based queries, simulating actual client requirements for customer data management. These exercises are conducted directly in the Dynamics AX 2012 client interface, ensuring alignment with live implementation scenarios.
