    feature introduced in MQ v8.0.0.4 fails with a "type
    initializer" exception.
    
    MQ trace of the failure shows the following:
    System.TypeInitializationException: The type initializer for
    'IBM.WMQ.Nmqi.UnmanagedNmqiMQ' threw an exception. --->
    System.NullReferenceException: Object reference not set to an
    instance of an object.

Local fix

  • Install higher version of MQ client along with Redistributable
    client.
    

Problem summary

  • ****************************************************************
    USERS AFFECTED:
    Users of the IBM MQ .NET v8 Redistributable client
    
    
    Platforms affected:
    Windows
    
    ****************************************************************
    PROBLEM DESCRIPTION:
    The logic to locate the MQ .NET runtime library (amqmdnet.dll)
    when running a .NET application has changed with
    resdistributable clients. A coding error within this change
    meant that the MQ .NET client was unable to locate runtime
    library when the environment was not associated with a full MQ
    installation.
    

Problem conclusion

  • The MQ .NET redistributable client has been updated to correctly
    locate the runtime library from the client directory if a full
    MQ installation is not present.
