  • I guess this happens when Network is very busy.

    I need time to move the code out of big project. In the meantime, please talk to MS developer in what case this exception throws?  MSDN does not mention any exception for this API call.

  • Hi,

    I have searched head files, and found it maybe
    E_INVALIDARG( One or more arguments are invalid ) in winerror.h
    Or
    COR_E_ARGUMENT(An argument does not meet the contract of the method) in corerror.h

    Best regards,
    Jesse

  • Like i mentioned in beginning, "when retry with the same input parameter", it is ok. so the exception is confusing.
