Open visual studio solution file Assignments.sln.

Run Assignment.Demo project or run Assignment.Tests from test tool.

More info on running tests is here Tests in C# and visual studio

Its rather simple

First add reference in your project to the library provided in this repo: Add reference to project

Next initialize Scheduler:

using Assignment1;
...
Scheduler a = new Scheduler(5);
...

After that create some tasks to schedule:

Task task = new Task(() => { Task.Delay(1000).Wait(); Console.WriteLine("omg windonzzz baka windonz"); });

And CancellationTokenSource:

CancellationTokenSource cts1 = new CancellationTokenSource(1);

And after that all you have to do is schedule your task(s):

a.ScheduleTask(ta, Scheduler.Priority.HIGH, cts1);

If you want to allow tasks to stop from scheduling you must add CancellationToken in task that you are willing to run.

CancellationTokenSource canc = new CancellationTokenSource(500);

Task t1 = new Task(() =>
{
    for (int i = 0; i < 10; i++)
    {
        if (canc.Token.IsCancellationRequested)
        {
            break;
        }
        else
        {
            Task.Delay(1000).Wait();
            Console.WriteLine("still not done windonzs");
        }
    }

}, canc.Token
);

And when you are ready to close task simply:

a.AbortTask(t1);

Or remove all tasks that are marked for canceling:

a.AbortAllThatRequireCancelation();

There is one more method that is given in this API and that is:

while (a.GetNumberOfTasks() > 0)
{
    Task.Delay(1000).Wait();
}

GetNumberOfTasks returns how much tasks are left to scheduler and/or are executing. So when that number reaches zero that means that scheduler is empty.

public Scheduler(int maxTasksAllowed) scheduler constructor, used to create new scheduler

public void ScheduleTask(Task task, Priority priority, CancellationTokenSource cts) method used to schedule tasks to scheduler

public int GetNumberOfTasks() method used to get number of tasks on queue waiting to be executed or that are already executing

public void AbortTask(Task task) method used to abort task that is executing

public void AbortAllThatRequireCancelation() method used to abort all tasks that are marked for cancellation

Also, following enum is used to define priorities for scheduler

public enum Priority : UInt16
{
    HIGH = 2,
    NORMAL = 7,
    LOW = 19,
}
