I have created a package out of my custom activity. I have put the package in the packages directory and installed it into my project which was successfully completed. I can see the list of activities under the custom activity. Now when i am trying to drag and drop one of the activities, i get an error message box saying
“Cannot create an instance of ACTIVITY_NAME”
“Could not load file or assembly Version=18.104.22.168, Culture=neutral , PublicKeyToken = null” or one of its dependencies. The system cannot find the file specified."
