Applies To.NET Framework 4.6.1 .NET Framework 4.6.2 .NET Framework 3.5.1

October 11, 2016 Revised bulletin to announce that security updates 3135994 and 3135995 for the Microsoft .NET Framework 4.5.2 on Windows Server 2012, Windows 8.1 and Windows Server 2012 R2 have been rereleased to the Windows Server Update Services (WSUS) channel exclusively. This re-release does not apply to Windows Update or Microsoft Update Catalog customers. This re-release addresses an offering issue that prevented certain GDR customers within WSUS environments from receiving these updates if they had enabled the "automatically decline updates when a new revision causes them to expire" feature. There are no changes to the file payload. If you have already successfully deployed updates 3135994 and 3135995, you do not have to take any action.May 10, 2016 This security update has been re-released and contains some updated articles. This re-release is intended for LDR (limited distribution release) content customers only. We determined that there were some issues in certain printing scenarios because of a missing dependency. If you use LDR content, we recommend that you apply this updated security update. There are no changes in this re-release for GDR (general distribution release) content customers.
