Called by a linked ITargetBlock<TInput> to release a previously reserved DataflowMessageHeader by this ISourceBlock<TOutput>.
virtual void System.Threading.Tasks.Dataflow.ISourceBlock<T>.ReleaseReservation(System::Threading::Tasks::Dataflow::DataflowMessageHeader messageHeader, System::Threading::Tasks::Dataflow::ITargetBlock<T> ^ target) = System::Threading::Tasks::Dataflow::ISourceBlock<T>::ReleaseReservation;
void ISourceBlock<T>.ReleaseReservation (System.Threading.Tasks.Dataflow.DataflowMessageHeader messageHeader, System.Threading.Tasks.Dataflow.ITargetBlock<T> target);
abstract member System.Threading.Tasks.Dataflow.ISourceBlock<T>.ReleaseReservation : System.Threading.Tasks.Dataflow.DataflowMessageHeader * System.Threading.Tasks.Dataflow.ITargetBlock<'T> -> unit
