Microsoft Dynamics 365 for Finance and Operations, previously known as Dynamics AX, is Microsoft's business application for enterprises. The new version contains a multitude of news and has a complete new architecture. In addition to the brand-new user interface and new and updated functionality, it also entails a transition to BI functionality based on Power BI, a whole new integration framework based on Data Entities and a very large amount of news for developers. It also is much more coupled to Lifecycle Services (LCS) as well as the brand new cloud-based licensing model. Based on experience from early customer implementation projects, the book gives insight in the do's and don'ts in the new release. A large part of the book is about the transition needed for developers to adapt to new ways of working with development. The target audience for this book is primarily Dynamics professionals, Application consultants and developers.
