Fixed in mono master a7a0f54d3af48c076939d9a99867c9dd6eb0e626, maccore master bumped in 7a8aa6cdc42bfca3e94fa45260eb475eae06009e.
Comment 3 Rolf Bjarne Kvinge [MSFT] 2015-12-01 19:26:24 UTC
@Zoltan, it's fixed for uint32, but not for int8 and int16.

Code (replace AppDelegate.cs with this in the test project): https://gist.github.com/rolfbjarne/a439c2853a9b8f7907df
