I just started getting this error:
Unhandled exception occurred while calling method 'projectService_ProjectMenuItemsRequested' of type 'CKS.Dev.VisualStudio.SharePoint.Deployment.DeploymentSteps.ActivateSelectedFeaturesProjectExtension, CKS.Dev, Version=18.104.22.168, Culture=neutral, PublicKeyToken=487fd6341a5c701f'. Exception: System.NullReferenceException. Message: Object reference not set to an instance of an object.
It happens when opening my project, trying to attach to IIS processes, adn trying to copy assembly to GAC. I assume it would happen on other actions as well.
I can't think of what I may have changed to cause this error. I have attempted to reinstall CKSDev, as well as rebooting my machine, and always get this problem (not intermittently).
I do not get this error when opening a smaller project, so it must be something in this project, but I have no idea.
