I have an application which uses SqlConnection.ClearAllPools to close all connections before dropping a database.

There is a case where a connection is still there. This connection had been created in another application domain.

So I wonder which connections are closed by SqlConnection.ClearAllPools?

  • Only the connections opened by the calling process (or AppDomain)?
  • All the connections opened by this machine?
  • ...?
.net sql-server ado.net connection-pooling
