Best Practice LongRunning Task creation
As you already mentioned, you can use the CancellationToken. Do it this way:
var cancellationTokenSource = new CancellationTokenSource();Task.Factory.StartNew(RemoveFromBlockingCollection , TaskCreationOptions.LongRunning , cancellationTokenSource.Token); And later in your code, you can cancel the task with:
cancellationTokenSource.Cancel();In your long running task you can ask the token, if cancellation was requested:
if (cancellationTokenSource.Token.IsCancellationRequested)
