Visual Studio Preview: Report Could Not Be Built

**SOLVED*

I stumbled on a solution to this while working on something else. It probably coincides with what someone posted in reply to me here, but I didn't understand it at the time. 

What needed to be done is in this Stack Overflow link here: https://stackoverflow.com/questions/36272514/the-report-definition-has-an-invalid-target-namespace-rsinvalidreportdefinition

At the time I posted this request for help, I had never edited a report in code view - only design view. Take note of the fact that the person answering in that Stack Overflow link says "The minute you change any fields {in design view} it will revert to the 2016 schema."

Hope this helps someone in the future!
