SmartConnect is one of the easiest ways to build maintainable data integrations with Microsoft Dynamics GP. With this release, SmartConnect is now compatible with Microsoft’s latest version of Dynamics GP 2015. That means that SmartConnect is compatible with Microsoft Dynamics GP 2015, 2013, and 2010. Please note, however, that Dynamics GP 10 is no longer supported with the new version. This is just one more reason to be thinking about upgrading to Dynamics GP 2015.
