What is an AggregateException?
AggregateException is used to consolidate multiple failures into a single, throwable exception object. It is used extensively in the Task Parallel Library (TPL) and Parallel LINQ (PLINQ). For more information, see Exception Handling and How to: Handle Exceptions in a PLINQ Query.
What are the tasks to be handled by exception handling?
Exceptions are propagated when you use one of the static or instance Task. Wait methods, and you handle them by enclosing the call in a try / catch statement. If a task is the parent of attached child tasks, or if you are waiting on multiple tasks, multiple exceptions could be thrown.
Does await throw AggregateException?
When you await Task that was terminated by the exception, await mechanism implicitly unwraps propagated AggregateException, leaving you with the underlying exception. However, when you throw it inside the async void method, it cannot be attached to the task, as there is no task.
What is InvalidOperationException in C#?
InvalidOperationException is used in cases when the failure to invoke a method is caused by reasons other than invalid arguments.

How to handle an exception contained in an aggregateexception?
An exception contained by this AggregateException was not handled. Ordinarily, an exception handler that catches an AggregateException exception uses a foreach loop (in C#) or For Each loop (in Visual Basic) to handle each exception in its InnerExceptions collection.
Are there any warranties for the use of aggregateexception?
Microsoft makes no warranties, express or implied, with respect to the information provided here. Represents one or more errors that occur during application execution. The following example catches the AggregateException exception and calls the Handle method to handle each exception it contains.
When to use aggregateexception in parallel in Java?
In a real world scenario more than one exception could happen (in different threads) – the AggregateException is just a “container” for all exceptions occuring while Parallel is running so that you don’t lose any exception… AggregateException is often used for catching exceptions, that might occur when waiting for a Task to complete.
How to initialize an instance of the aggregateexception class?
Initializes a new instance of the AggregateException class with references to the inner exceptions that are the cause of this exception. Initializes a new instance of the AggregateException class with references to the inner exceptions that are the cause of this exception.
