Releases the right to pass the ownership of the message identified by the DataflowMessageHeader from this ISourceBlock<TOutput> to the ITargetBlock<TInput>.

- messageHeader
- DataflowMessageHeader
The DataflowMessageHeader of the reserved message.
- target
- ITargetBlock<Tuple<T1,T2>>
The ITargetBlock<TInput> that currently holds the reservation.
Implements
Exceptions
The messageHeader is not valid.
The target is null (Nothing in Visual Basic).
The target did not have the message reserved.
Remarks
The ITargetBlock<TInput> that holds the reservation need not be linked from this ISourceBlock<TOutput> instance. Moreover, this ISourceBlock<TOutput> instance may have never offered the message directly to the ITargetBlock<TInput>. It is required that this message has been previously reserved for the same ITargetBlock<TInput>.
