How do I enable a Checked context from .csproj file?

[CharlesTaylor7]

Is there a way to set a default checked context for my whole assembly from the .csproj file?
More generally, what's the best way to customize compiler options if I'm using VSCode and not Visual Studio?

The documentation on this page only goes over what to do in Visual Studio:
