Today, we are releasing the February 2018 Security and Quality Rollup.

Security


No new security fixes. See .NET Framework January 2018 Security and Quality Rollup for the latest security updates.

Quality and Reliability


This release contains the following quality and reliability improvements. It includes the same quality improvements that were part of the January 2018 Preview of Quality Rollup.

ASP.NET

  • Behavior change of HttpCookieCollection.Set, in .NET Framework 4.5.2 and later. If the app uses Set-Cookie header and also use Cookies.Set to add new cookie, the cookie set via Set-Cookie will not be in the response. [513614]
Identity

  • UserPrincipal.GetAuthorizationGroups does not use Kerberos transition when it should, and LDAP operation fails if a group has an SID in its sidHistory, for .NET Framework 4.6.2. [484146]
SQL

  • SqlConnection can hang in Close/Dispose after getting network exception during SqlBulkCopy writes, for .NET Framework 4.6 and later. [523503]
WCF

  • Deadlock between SharedTcpTransportManager.OnClose and OnReceiveComplete causing hang. [454558]

Note: Additional information on these improvements is not available. The VSTS bug number provided with each improvement is a unique ID that you can give Microsoft Customer Support, include in StackOverflow commentsor use in web searches.
