Update adds the "CLR strict security" feature to SQL Server

Applies to: SQL Server 2016 Enterprise CoreSQL Server 2016 EnterpriseSQL Server 2016 Developer


This update adds the CLR strict security feature to Microsoft SQL Server.

However, the feature is turned off for backward compatibility in SQL Server. Because of database level compatibility, the feature cannot be enabled by using the sp_configure 'clr strict security', 1 command.

To enable CLR strict security, add trace flag 6545 to the server Database Engine Service Startup Options. Remember that this trace flag can be used only together with SQL Server startup options. It cannot be set by using the DBCC TRACEON command.
