Welcome to this course on X++ Technical Fundamentals for Dynamics 365 Finance & Operations (D365 FO).

X++ is the core programming language used to build, customize, and extend business logic in Microsoft Dynamics 365 Finance & Operations. If you are planning to work as a D365 FO technical consultant, developer, or techno-functional professional, a strong understanding of X++ is not optional—it is essential.

Many learners find X++ confusing at the beginning. This is not because the language itself is difficult, but because most explanations jump directly into advanced topics without clearly explaining the fundamentals. Concepts like tables, select statements, extensions, Chain of Command, and transactions often feel overwhelming when the basics are not solid. This course is designed to bridge that gap.

In this course, we will start from the absolute fundamentals of X++, assuming no prior experience with the language. You will gradually build your understanding of X++ syntax, data types, control flow, classes, and methods before moving into how X++ interacts with the D365 FO framework. Each concept is explained with practical examples so that you not only understand what to write, but also why it is written that way.

You will learn how X++ works with:

• Tables and database operations

• Business logic implementation

• Forms and UI interaction

• Extensions and best practices followed in real projects

The course focuses on real-world usage, not just theoretical knowledge. The examples and explanations are aligned with what you will actually encounter in D365 FO projects, support tickets, and interviews. By the end of this course, you should be comfortable reading existing X++ code, debugging issues, and writing clean, maintainable code that follows Microsoft’s extension-based architecture.

This course is especially helpful for:

• Beginners who want a structured and simple entry into X++

• Functional consultants looking to become techno-functional

• Junior developers who want to strengthen their fundamentals

• Professionals preparing for D365 FO technical roles or interviews

My goal with this course is to make X++ simple, logical, and practical, so that you gain confidence step by step. Once your fundamentals are strong, advanced concepts and real project work become much easier to handle.

Let’s get started and build a strong foundation in X++ together.
