* FreeBSD is listed on CoreCLR GitHub repo (https://github.com/dotnet/coreclr).
See current build status here: http://dotnet-ci.cloudapp.net/job/dotnet_coreclr/job/master/...
* Also, see doc here (last updated in feb though): https://github.com/dotnet/coreclr/blob/master/Documentation/...
* Laslty, FreeBSD arrived on azure last week, so it would be quite surprising if support was dropped.
