.NET Framework 4.7 entered wide release yesterday (see https://blogs.msdn.microsoft.com/dotnet/2017/05/02/announcing-the-net-framework-4-7-general-availability/).
Don't put it on your Exchange Servers. Don't put it on your Lync Servers (Skype for Business). I've not seen a specific announcement about them, but I would also avoid putting it on SharePoint Servers and SQL Servers until a support statement is out. Ensure you don't just "approve all" with this update. :) Regards, Michael B.
