Load activity in Windows Workflow Foundation (WWF) from a Nuget package

I have a Windows Workflow Foundation (WWF) project. I want to import an activity package from a Nuget package and load it into the activity panel. I am currently loading an activity in the activity panel through DLL. Also, I'm able to export Nuget package in Bin & able to load activity through DLL. But I want to expose the Nuget package in memory to load in the activity panel. We also want to manage installed or uninstalled package through the Nuget package.
