    The following target has been ported from TerraFX.Interop.Windows.
    See: https://github.com/terrafx/terrafx.interop.windows.
    Using [module: SkipLocalsInit] suppresses the .init flag for local variables for the entire module.
    This doesn't affect the correctness of methods in this assembly, as none of them are relying on the
    JIT ensuring that all local memory is zeroed out to work. Doing this can provide some minor
    performance benefits, depending on the workload.
