First, within the Program.Program()
static constructor I have this code:
AppDomain.CurrentDomain.UnhandledException += (s, eargs) =>
LogException((Exception)eargs.ExceptionObject);
Application.ThreadException +=
(s, eargs) => LogException(eargs.Exception);
Then, if I deliberately do (for example) a divide-by-zero, it's caught. However, none of the other exceptions from within the thread loop are caught, like this one - its stack trace is:

When that ReflectPropertyDescriptor
calls my code and I throw a custom exception, the system silently swallows it and I can't log it.
It turns out that the majority of my lost exceptions can be seen in the BindingComplete
event. It'll have to do.
