Hi Sivalingam,
Based on the description in the thread you linked to, this problem only appeared once and you had not been able to reproduce it again. Is that correct?
Basically it seem that MEF encountered an error while trying to access its own CompositionContainer. I'm not aware of what can throw this kind of exception but in the mean time (until you are able to reproduce the error again) please check if there is any using block where you are using MEF's CompositionContainer or any part where you are invoking its Dispose method. MEF' CompositionContainer class implements IDisposable, so doing any of the above will dispose the container and possibly throw this exception.
Thanks,
