I would like to ask why this two approaches are different and returns two different set of values:

The first one which is correct in my opinion return values from 0 to 8 and works on different threads (LINQPad code):

void Main() {     var newTasks = Enumerable.Range(0, 9).Select(x => Task.Run(() => DoSomething(x)));      Task.WhenAll(newTasks); }      public int DoSomething(int value) {     return value; } 

Second, which is not correct in my opinion which returns random values a specially 9 but also works on different threads.

void Main() {     var tasks = new List<Task<int>>();          for (var index = 0; index < 9; index++)     {         var task = Task.Run(() => DoSomething(index));                  tasks.Add(task);     }          Task.WaitAll(tasks.ToArray()); }      public int DoSomething(int value) {     return value; } 

Is it possible to modify the second one and get the result similar to first example?

Thanks for your answers.
