Power BI Desktop stores the M code for queries created via the Power Query Editor graphical interface or the Advanced Editor within M documents for repeatable execution. Similar to other languages and project types, code editing tools are available to support the development, documentation, and version control of M queries. Dataset designers can use Visual Studio or Visual Studio Code to author and manage the M queries for Power BI and other Microsoft projects. These tools include common development features, such as IntelliSense, syntax highlighting, and integrated source control.
