Like many I’m used to just downloading my developer resources from MSDN subscriber downloads or MS Dynamics Customer source etc.
Cleaning up my machines I lost the SDK for Visual Studio add-in creation in Dynamics GP. After trying to web search for it I didn’t find anything but the links to the GP2013 versions.
Looking at the installation media, found it under:
GP2015 R2 MDGP2015_R2_DVD_ENUS\Tools\SDK\VS Tools
Hopefully this post will help someone else to remind them more quickly to check the media for this and other components like eConnect.
The media for GP can be downloaded from MSDN or other locations on the internet.
See this customer source page, you will need to log into your account to access it:
