Dealing with the AggregateException thrown when calling task.Wait().

Question

I am new to the Task facility and am curious on best practice here. I am dispatching tasks something like:
Task task = Task.Run(
() =>
try
this.MyMethod(paramA, paramB);
catch
taskCancellationTokenSource.Cancel();
throw;
finally
semaphore.Release();
So if needed, the cancellation token can end things quickly and drop me quicker into the final bit of cleanup:
foreach (Task task in tasks)
try
task.Wait();
catch (AggregateException e)
foreach (Exception ie in e.InnerExceptions)
Logger...
throw;
catch (Exception e)
Logger...
throw;
Obviously this brings out only the first nested exception. What is the general way of handling this? How should rethrow in this scenario allowing me to log and track everything that may have occurred?
Thanks!

Hi

Per my understanding, you could catch System.Exception and switch on the types
catch (Exception ex)
if (ex is Exception || ex is AggregateException)
Logger...
return;
throw;
