8633: Development II in Microsoft Dynamics™ AX 4.0 (2 Days)
Introduction
This 2-day course introduces the student to development in Microsoft Dynamics AX using X++. This course starts with learning the basics of X++ and its relationship to object-oriented programming in addition to the tools that are required to develop in Microsoft Dynamics AX. The student then learns more about specific control structures, accessing the database using X++, and handling exceptions in Microsoft Dynamics AX. This course is meant to be an introductory course to development in Microsoft Dynamics AX using X++.
Audience
This course is intended for individuals who will be developing within Microsoft Dynamics AX using X++. This audience typically includes technical consultants who will be working with Microsoft Dynamics AX to develop customizations and modifications to meet clients' needs. This course will be most beneficial for someone who is new to the concepts of object-oriented programming and programming using X++. Additionally, consultants who are responsible for training or supporting the customer will benefit from this course.
