We recently released the January 2018 Preview of Quality Rollup.

Quality and Reliability

This release contains the following quality and reliability improvements.

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.
