I have a Visual Studio 2019 solution comprising of 4 projects. For 3 of the 4 projects, warnings are reported in Visual Studio's Error List window as normal. But for 1 of the 4 projects, all compiler warnings appear to be suppressed and for this 1 project no warnings are being reported in the Error List window at all.
If I introduce an error, that is reported in the Error List window as expected, but not warnings. I have added code that I am certain should cause a warning but still no warning is reported for the affected project.
What could cause all warnings for 1 project to be suppressed? How can I get warnings turned on again for this project?
