Priority Task Queue

C# TPL Priority Queue

The Need

I needed a way to post work items into a queue and have them processed one at a time, yet have the ability to post high priority items and get them done first.

The Solution

I've use a simple implementation of PriorityQueue to store the work items.
I've use TPL Task to handle the execution and continouation and thus eliminating the need for hard-to-test multi-threading code.

The Use

  int handledItems = 0;
  
  var subject = new PriorityTaskQueue<string>(
    item => handledItems++);

  for (int i = 0; i < 10; i++) {
    subject.Post("A" + i, 0);
  }

Limitations

PriorityTaskQueue is currently designed to process one item at a time.
