This is the community version of Visual Studio 2015.
I am using Setup Project (MSI) to create an installer for my VSTO add-in. I have done this many times in previous versions of VS and have never seen this behavior. VS2015 detects a huge number of dependencies that are not included in the add-in project links. Restoring projects and using the Refresh Dependencies team did not show any benefit. Has anyone else experienced this problem or know a solution?
Here is a snapshot of the Links section of my add-in project and the Detected dependencies list, which shows the installation project:
