Can't Serialize SEHException?

[Ken Durden]

I'm getting the following exception coming out of a block of unmanaged
C++ code.

Thread executed for 1.03 sec and died with the following exception:
External component has thrown an exception.

A.) I believe this to be a crash-type situation in the unmanaged code,
an access violation for example. Is this correct?

B.) When I try to serialize an object containing the Exception which
caused the failure (the SEHException above), I get the following
error. This seems to indicate that SEHException isn't serializable
because it can't call get_Source on it? Is there anything I can do to
get this exception across intact?

Thanks,
