@cheenamalhotra will this fix also be backported? |
We are going to backport the fix to M.D.S v1.1 and System.Data.SqlClient in .NET Core, while for .NET Framework, @saurabh500 can confirm if this could be considered? |
The original issue was found in .net framework. It seems to me this needs backporting to .net framework too. Edit: Sorry, 1.1.* is targeting .net framework. |

Fixes #237 by dooming the connection when transaction ends externally (re-created PR #495) .
As of now, this fix is promising and does not send connection back to connection pool, hence avoiding enlistment in aborted transaction.
Alternatively, if we want to send connection back to pool, it needs to be in same state as any other connection in pool with no aborted transaction reference, but that doesn't seem likely to be achieved without complex changes in the driver that would also be a risky attempt. Investigations are in progress that will bring back same performance, but in order to address the issue on priority, I would propose this fix in the driver for end user application consistency.
