Hi again @szpeter. After further investigation I narrowed the issue down do the MSVC Toolset Version. In summary, v14.26 still works but v14.27 doesn’t and we are going to investigate this internally. So the SDK version can be the latest Windows 10 version you have, but you need to make sure that the MSVC Toolset Version is set to v14.26. You can do this in the Properties of your Project, like in the following image:
Since this was a very recent update from Microsoft, I didn’t notice it until today when I tried to build something after the update.
Hopefully you can keep working with a solution based project on Windows and thanks for the report.
