I've changed my workspace_publish branch to main and I see no change -- no folder.  I'm stuck about 10% of the way into this blog entry.  The first two were top notch, this one has me stumped.
 
Edit -- Got it.  I needed to publish something.  I needed to make a file and change it after creating the DevOps in order for the Publish command to create a set of output files for the repository.  I had a ton of stuff in the workspace prior to setting up DevOps, but nothing that I changed.  I added one empty file and everything got captured in the TemplateForWorkspace.json and TemplateParametersForWorkspace.json.
 
At this point things are becoming less intuitive.  Up until this point I could figure out what each step was doing and why.  This part is a little less apparent.
