Next, the code creates a Task object for the method represented by the countDelegate variable.
The Task constructor takes as parameters the delegate and the value 5 that it should pass to the
delegate’s method.
The code then calls the Task’s Start method to start the task running on a new thread.
The program then performs its own count on the UI thread. When it finishes it displays a message
in the Label and re-enables the program’s Button.
Having finished its work, the code uses the await keyword to wait for the Task to finish and saves
the result returned in the variable result.
The code finishes by displaying the result it received from the asynchronous thread.
The following code shows the new version of the Count method.
// Count pausing 1 second between numbers.
// Return the final value displayed.
private int Count(object maxObj)
{
int max = (int)maxObj;
for (int i = 1; i
