While researching material for Arrays for a part session for Cologne 2018, I have found that the setting I have been changing - "Use Zero Based Arrays" - does not get changed after changing it on screen, and doing Build and Re-build actions. It seems to require that I close and reload the solution before the new setting takes effect.
I therefore would assume that this could also be the case for all properties ???
Currently I am working around this okay, but I have found some possibly MAJOR concerns with Arrays and 0/1 base ... I will explain these issues in another post.
