Hi,
I'm getting this exception randomly in one webservice, it used to happen in the first call only, and in the second calls and so on it works fine ... and after a while without use the webservice it happens again. It seems to be that when the AppDomain is not loaded, the first time fails... and subsequent calls are ok; when IIS shutdown the AppDomain... the next call will fail again.
