Timeout manager
The timeout manager has been removed from NServiceBus 8, so the EnableTimeoutManager backwards compatibility API has been removed from the transport. The timeout migration tool should be used to migrate any remaining timeout messages.
Certificate connection string options removed
The certPath and certPassphrase connection string options have been removed. The SetClientCertificate API should be used instead.
requestedHeartbeat connection string option removed
The requestedHeartbeat connection string option has been removed. The SetHeartbeatInterval API should be used instead.
retryDelay connection string option removed
The retryDelay connection string option has been removed. The SetNetworkRecoveryInterval API should be used instead.
Transport no longer claims to support TransportTransactionMode.None
The transport does not have any functional difference between TransportTransactionMode. and TransportTransactionMode. modes, but there has been no way to indicate this before NServiceBus 8. Now that NServiceBus 8 has enabled this, the transport now only supports TransportTransactionMode..
IRoutingTopology SetupSubscription and TeardownSubscription changes
The type parameter of the SetupSubscription and TeardownSubscription methods of the IRoutingTopology interface has changed from System. to NServiceBus.. Custom routing topology implementations will need to be updated.
