So we're trying to make sure that our application scale perfectly on 4K monitors. We successfully did that, but now the app will not run on windows 7,8,8.1. It can only run on windows 10,11.

So by uncommenting the code below, the app will not run on older windows. Is there anyway around it, where we can keep the dpiAware true for windows 10,11 and false for older versions so users with older version of windows can still run the app?

Note: i'm using .NET 4.7.2 Thanks

  • Hmm, this manifest shouldn't work at all for ClickOnce-deployed apps. Consider [using pinvoke](https://stackoverflow.com/a/43537991/17034). – Hans Passant Dec 21 '21 at 00:53
