Quality and reliability improvements

SQL1

Addresses an issue that caused breaks in mitigated compatibility that were seen in some System.Data.SqlClient usage scenarios.

WCF2

Addresses an issue that caused a race condition with Internet Information Services (IIS)-hosted net.tcp WCF services. When the port sharing service was restarted, the issue caused the service to be unavailable.

WinForms4

Addresses an issue in which an application may have problems after the application user interface is rendered.


1 SQL Server (SQL)
