Microsoft.SqlServer.Management.XEvent 命名空间

The common object model for creating and using SQL Server Extended Events in client and server components of SQL Server. The Extended Events infrastructure supports the correlation of data from SQL Server events. Under certain circumstances, the infrastructure can also be used to correlated data from the operating system and database applications.
