We are retiring the Microsoft Dynamics AX Developer Center on MSDN at the end of September 2017. (The Developer Center contains links to whitepapers and other downloads that you can also find on the Microsoft Download Center.) We will redirect all of the current pages on the Developer Center to appropriate pages in the MSDN Library or on the Microsoft Download Center. You can still find the Dynamics AX product documentation in the MSDN and TechNet libraries.
