Changed

Remove configurable retry logic safety switch

The App Context switch "Switch.Microsoft.Data.SqlClient.EnableRetryLogic" will no longer be required to use the configurable retry logic feature. The feature is now supported in production. The default behavior of the feature will continue to be a non-retry policy, which will need to be overridden by client applications to enable retries.

SqlLocalDb shared instance support

SqlLocalDb shared instances are now supported when using Managed SNI.

  • Possible scenarios:
    • (localdb)\. (connects to default instance of SqlLocalDb)
    • (localdb)\<named instance>
    • (localdb)\.\<shared instance name> (*newly added support)
