I want to set a breakpoint in my C#/Xamarin Studio project that breaks on all exceptions, EXCEPT those that have to do with task cancellation. Is that possible?


You should use separate catch for CancellationException

try
{
    //do your stuff here
}
catch(CancellationException ex)
{
    //behave cancellation
}
catch(Exception ex)
{
    //Here handle other exceptions
    //Also you can put break point here
}

Manage exceptions with the debugger, You should use separate catch for CancellationException try { //do your stuff here } catch(CancellationException ex) { //behave cancellation } catch(Exception ex)  If you do not use a Wait or WaitAll method to wait for the task, then the task just sets its status to Canceled. If you are waiting on a Task that transitions to the Canceled state, a System.Threading.Tasks.TaskCanceledException exception (wrapped in an AggregateException exception) is thrown. Note that this exception indicates successful cancellation instead of a faulty situation.


If you know your entry point exactly, you could write a code like this:

try
{
   ....
}
catch (CancellationException)
{
     throw;
}
catch (Exception ex)
{

     //otherwise handle this exception
}

If not, you could catch at application domain level using the event ApplicationDomain.UnhandledException. More details here: http://developer.xamarin.com/api/event/System.AppDomain.UnhandledException/

Tasks Also, learn how to configure the debugger to always break execution for some exceptions. In a Visual Basic application, the debugger manages all errors as while a second method throws the same exception but doesn't handle it. Caught exception. */ A task-based continuation enables you to handle any exception that is thrown by the antecedent task. A task-based continuation always runs; it does not matter whether the task completed successfully, threw an exception, or was canceled. When a task throws an exception, its task-based continuations are scheduled to run.


I think it is possible. You may add catching all exceptions listening to System.Exception. Add the condition and check the type of exception in order to skip task cancelled exceptions. Exception in the local scope is available as $exception, so the condition will look like !($exception is System.Threading.Tasks.TaskCanceledException)

C H A P T E R 15 - Debugging C++ With dbx, But we can handle exceptions and it's actually standard practice in . If not found​, it's considered an Unhandled Exception or Second Chance Exception Run() or Task. Settings Window available from Debug | Windows | Exceptions Setting​. When enabled, Visual Studio will break only on exceptions in your own code. For example, if you cancel the task group tg1 in the illustration of the parallel work tree, all tasks in the tree (t1, t2, t3, t4, and t5) are affected. If you cancel the nested task group, tg2, only tasks t4 and t5 are affected. When you call the cancel method, all child task groups are also canceled. However, cancellation does not affect any parents of the task group in a parallel work tree.


Automatically pause on any exception | Web, This chapter describes how dbx handles C++ exceptions and debugging C++ templates, including a summary of commands used when completing these tasks and Set breakpoints on all member functions of a class (see Setting Breakpoints in exceptions that interests you, but you do not know the name of the exception  In the Exception Settings window (Debug > Windows > Exception Settings), expand the node for a category of exceptions, such as Common Language Runtime Exceptions. Then select the check box for a specific exception within that category, such as System.AccessViolationException. You can also select an entire category of exceptions.


Debugging with GDB - Stopping and Continuing, In the DevTools, you can automatically pause on any exception (especially useful for uncaught exceptions). Even if you use a continuation to observe an exception in a child task, the exception still must be observed by the parent task. Exceptions that indicate cooperative cancellation. When user code in a task responds to a cancellation request, the correct procedure is to throw an OperationCanceledException passing in the cancellation token on which the request was communicated. Before it attempts to propagate the exception, the task instance compares the token in the exception to the one that


Rider advanced debugging with breakpoints, In any selected frame but the innermost, this makes your program stop as soon This command sets an unconditional breakpoint on all matches, printing a list of all catch exceptions: You can set breakpoints at active exception handlers by using (gdb) b String::after [0] cancel [1] all [2] file:String.cc; line number:867 [3]​  gather, by default, will return when an exception is raised by any of the tasks, or whenever all tasks are done if no exception is raised. As we’ve seen, if return_exceptions is True it will return when all tasks are “done” even if some raised an exception.
