Also missing: pinning spans. So this also doesn't work
private static unsafe void SpanInFixedContext(ReadOnlySpan<byte> s) {
fixed (byte* dest = s) {
//do something
}
}Previously, we would be able to add System.Memory.dll manually, but doing so now will cause conflicts since mscorlib already includes it (even if partially).
