I spoke too soon. This isn't the cause of my bug. I think my exception must
be on the main thread somewhere. I'll look into that.
However, I did write a test program and found that the Mono 2.0 profile does
not behave like MS .NET 2.0 with regard to unhandled exceptions. They (MS)
introduced a breaking change with 2.0 that causes unhandled exceptions on
any thread to terminate the app in most cases. You turn off that change with
the <legacyUnhandledExceptionPolicy> element. I hate this change, but they
do have some good reasons as covered at
http://msdn2.microsoft.com/en-us/library/ms228965.aspx and in this article:
Mono didn't introduce the breaking change in the 2.0 profile. Unhandled
exceptions can be taken care of by an UnhandledExceptionHandler without use
of the <legacyUnhandledExceptionPolicy> element.
Is this by design? Or is it a compatibility bug?
