Microsoft has recently released version 1.5 of their Dynamics Mobile solution, which is a set of tools, device applications and server tools to enable synchronization of data between mobile devices and Dynamics AX (formerly Axapta) and Dynamics NAV (formerly Navision). It includes tools to develop your own application as well as a ready made application called “Dynamics Mobile Sales”. It uses SQL Compact 3.5 extensively, such a Merge Replication, and boasts features such as:
Complete no-coding customization of the application (based on XML), on a per-role basis.
Ability to queue web services requests when off-line.
Merge replication of lookup data from NAV and AX ERP servers.
Server based deployment and monitoring tools.
Well worth considering if you need to integrate with one of these backend systems.
