Oh, you are absolutely right, I was able to reproduce the issue. Thank you for reporting it.

Can you please download a new build of 2018.2 preview version - from the same URL (it should report itself as 5.52.0.4 or later on the 1st page of the installation wizard), rebuild, and retest?

Best regards

I suppose you have re-built your program after installation of new QuickOPC, right?

If so, I cannot tell more without actually going deeper into analyzing the hang. Can you please follow the steps described here?: kb.opclabs.com/Troubleshooting_program_hangs

Thank you

Hi,

unfortunately I have the same thing with this alpha version.

I did the test with different assembly versions, results :

QuickOpc 5.40 : OK
QuickOpc 5.50 : OK
QuickOpc 5.51 : KO
QuickOpc 5.52 (alpha) : KO

Regards.

The 2018.1 version is likely to be released in March 2018.

I will send you a link to an alpha version to the email you used to register with these forums.

Best regards

This should not be happening, but we have seen it recently in other situation too. If it is the same thing, we have a fix already, but it will only be available to the public in the upcoming version (2018.1).

If you are interested, I can send you an alpha version for private testing. Let me know.

Hello,

this is just a test case
private void Client_DataChangeNotification([JetBrains.Annotations.NotNull] object sender, [JetBrains.Annotations.NotNull] OpcLabs.EasyOpc.UA.OperationModel.EasyUADataChangeNotificationEventArgs e)
        {
            Console.WriteLine("Nouvelle valeur {0} : {1}", e.Arguments.NodeDescriptor.NodeId, e.AttributeData.Value);
        }
