The type initializer for 'IBM.WMQ.Nmqi.BindingsNmqiMQ' threw an exception

When trying to connect to MQ in bindings mode (I have a server set up locally), I get the following exception:

 System.TypeInitializationException: The type initializer for 'IBM.WMQ.Nmqi.BindingsNmqiMQ' threw an exception. ---> System.NullReferenceException: Object reference not set to an instance of an object.
   at IBM.WMQ.Nmqi.NativeManager.InitializeNativeApis(String mode)

   at IBM.WMQ.MQQueueManager..ctor(String queueManagerName, Hashtable properties)
   at Project.MQConnector.CreateConnectAndAddQueueManager(QueueManagerConnectionDetails connDetails)

The error occurs when trying to connect to a queue manager as follows:

Constructor:

Friend queueManagerConnectionProperties As New Hashtable()
queueManagerConnectionProperties.Add(MQC.THREAD_AFFINITY_PROPERTY, True)
If My.Settings.MQConnectAsClient Then
    queueManagerConnectionProperties.Add(MQC.TRANSPORT_PROPERTY, MQC.TRANSPORT_MQSERIES_CLIENT)
Else
    queueManagerConnectionProperties.Add(MQC.TRANSPORT_PROPERTY, MQC.TRANSPORT_MQSERIES_BINDINGS)
End If

queueManagerConnectionProperties.Add(MQC.CONNECT_OPTIONS_PROPERTY, MQC.MQCNO_HANDLE_SHARE_BLOCK Or MQC.MQCNO_RECONNECT_Q_MGR) ' have handle-sharing with call blocking

And in the CreateConnectAndAddQueueManager method (where connDetails is just a store for the port, host, name, etc.):

 Dim specificQMConnProperties As Hashtable = CType(queueManagerConnectionProperties.Clone(), Hashtable)
 specificQMConnProperties.Add(MQC.CHANNEL_PROPERTY, connDetails.Channel)
 specificQMConnProperties.Add(MQC.CONNECTION_NAME_PROPERTY, connectionName)
 Dim qmgr As MQQueueManager = Nothing

 Try
     qmgr = New MQQueueManager(connDetails.Name, specificQMConnProperties)
 Catch ex As MQException
     ' error handling
 End Try

I have the following environment variable:

NMQ_MQ_LIB=mqm.dll

When I connect using a managed connection (NMQ_MQ_LIB=managed; and don't set the MQC.TRANSPORT_PROPERTY), it works fine.

Any thoughts?

Looking at your latest comment. You have some unwanted entries in GAC. You need to do some clean up.

1) Open a command prompt.

2) Run amqiregisterdotnet.cmd /u command to unregister MQ .NET assemblies.

3) Check Windows GAC what MQ .NET assemblies. Make sure there are no MQ .NET entries. If there are some, try unregistering manually using gacutil command.

4) Then run the command amqiregisterdotnet.cmd to register the assemblies again.

Hope this helps.
