Click the Publish Extension
option in the Extension Builder Toolbar. This will create a package
containing your project files that others can copy into their install and use but not
modify.
The published extension will be saved to this directory on your machine:
[%ProgramData%]\Discovery\AddIns\Scripted[MyExtension.dstool].
To share your project, send the .dstool file to another
Discovery user and ask them to put it in the same directory on
their machine.
Instruct them to restart Discovery, and the new extension will
appear in the tab for your tool within Discovery.
