This just started today: whenever I open an instance of the VS 2017 IDE, I get a yellow bar informing me of a new version of Visual Studio 2019, which pushes down the existing windows thus reducing the visible area of the windows.
I don't have or use VS 2019, and at this moment in time I don't care about its new versions. The first time it happened I clicked the "x" thinking that would be the end of it, and when it did it again I clicked "More info" with the same result. How do I stop this?
Posts like this erroneously point people to the "Tools | Options | Environment | Extensions and Update" which, as the OP notes, is about updates to extensions, not the IDE.
I've developed an extension for Visual Commander: Block Visual Studio 2019 installation prompts in VS 2017.
But these messages all stopped to appear by themselves today on my machine...
