Parameters
- trackingContext
Type: Microsoft.ServiceBus.Tracing. . :: . .TrackingContext
The context information associated by a transaction tracking this operation.
- lockTokens
Type: System.Collections.Generic. . :: . .IEnumerable< (Of < ( <'Guid> ) > ) >
The collection of lock tokens bound to the locked message instances.
- timeout
Type: System. . :: . .TimeSpan
The time span interval the operation waits before it times out.
- callback
Type: System. . :: . .AsyncCallback
An AsyncCallback delegate that references the method to invoke when the operation is complete.
- state
Type: System. . :: . .Object
A user-defined object that contains state information about the asynchronous operation.
Return Value
Type: System. . :: . .IAsyncResult
An IAsyncResult that references the asynchronous operation to suspend processing of messages.
Remarks
Defer is called by the user when the consumer is not ready to process the message to defer the process into the future. After a message is Defered, the message can be received again with a call to Receive (messageReceipt).
