Description Goncalo Oliveira 2012-09-27 12:36:36 UTC
I'm getting occasional random exceptions when debugging with VS.
It does not occur always with the same scenario, it's completely random, but it does occur very frequently.
Might be worth saying that this is happening since 4.2.5 and 4.2.6 update.

There's no information in the exception details except for
Unhandled exception: System.AggregateException.

The output says nothing
