New Microsoft Dynamics Snap sample applications provide functioning end-to-end capabilities in source code form. By using the techniques employed by the new samples, partners and customers can build solutions that access the data and processes in Microsoft Dynamics AX from the productivity and collaboration tools of the 2007 Microsoft Office system. Two snap applications are now available with Microsoft Dynamics AX 2009: "Business Data Lookup" and "Expense Entry."
