C# TPL how to know that all tasks are done?

Question

I have the Loop which generates tasks.

Code:

Task task = null;
foreach (Entity a in AAAA)
{
  // create the task 
  task = new Task(() => {
    myMeth         


        

Answer 1

I f you replace this with a

 Parallel.ForEach(...,  () => myMethod(a), ...)

Then you get an automatic Wait on all tasks at the end of the ForEach.

And maybe run the ForEach from a separate Task.
