Dynamics NAV 2013 introduces several development changes. There are changes regarding the development environment, with new features and object properties, and changes in the standard C/AL code, which has been redesigned in some areas.
Development Environment is the former Dynamics NAV classic client. In previous versions, the classic client was used both as an application client for end users and for development purposes. With Dynamics NAV 2013, the classic client is no longer available as an application client but has remained as the development environment. That is why it has been renamed to Microsoft Dynamics NAV Development Environment.
The development environment in Dynamics NAV 2013 introduces several improvements, including:
New object types
Enhancements on the development of object types that existed on previous versions
New features
New object properties
Better .NET interoperability
