Question

Consider this example

var task =Task.Factory.StartNew(()=>Console.WriteLine("test"));

task.ContinueWith(antecendent =>
        {
            ExceptionProcessor.HandleError(task.Exception.Flatten());
        }, TaskContinuationOptions.OnlyOnFaulted);

In this example resharper predicts that there is a possible null pointer exception in task.Exception.Flatten() as it assumes task.Exception could be null .

But for all realistic scenarios it is not going to be null as the parameter TaskContinuationOptions.OnlyOnFaulted ensures the method gets called only when an exception occurs.

So How do I tell Resharper to ignore all similar warnings ?
