Tim Wappat has given us something precious. I am late to the party, though.
I didn’t realise that Microsoft Dynamics GP 2018 R2 shipped with a VS Tools version that’s incompatible with anything above Visual Studio 2015.
This realisation hit me when I tried to install and configure GP 2018 R2 on my virtual machine for an upgrade project.
Obviously, the first place to search for a resolution was our GP forum. This post by Richard Wheeler pointed me to the right direction. Tim’s Visual Studio extension saved me from going insane.
Thank you so much, Tim!
