Hey, thanks for the response. Yes, I saw that tool under content. When I double clicked it I could add existing files to the content, but building always failed. I found a youtube video (https://www.youtube.com/watch?v=rjXZdJLWqL8 18:29) where the programmer went through this process, but I didn't have a bin folder.
The issue, I think, was I tried to add the 2017 templates from this github page: https://github.com/MonoGame/MonoGame/issues/6695 but I don't think the Pipeline could actually see the content I was trying to add.
I'm going to do a fresh install as they do in the youtube video. Thanks again for commenting, I may yet be back.
