Thank you. Our setup was quite similar, in fact.

I have further tried to reproduce the issue, but without success. I think it may actually be not *directly* related to the .NET Framework version or the target CPU, but rather to things like timing/threads, which are not deterministic and can be different on our computers, even if the software versions are identical.

At this point, unfortunately, I am unable to provide further help, until reproduced on our side.

Do you actually necessarily need to do that? That is, do you really need to build for x64?

Best regards

QuickOPC 2016.2 has not been exhaustively tested under .NET Framework 4.6.2, but in general we expect it work.

I have attempted to reproduce the problem, but was so far unsuccessful.
I have tested on Windows 10 Enterprise 2015 LTSB (x64, English). Same version and build of QuickOPC as in your test.

Questions:

1. Which operating system have you used?
2. Besides .NET Framework 4.6.2, were there other versions of the framework installed at the same time?

Thank you

Building with .Net 4.6.2 and x64 causes InvalidOperationException was created by Erik
Hello,

Using .Net4.6.2 and setting release to x64 causes the following crash:

An unhandled exception of type 'System.InvalidOperationException' occurred in OpcLabs.EasyOpcUA.dll

Additional information: Precondition failed: SdkCertificateValidationEventHandler == null


Additional info:
  • Tested with both "QuickOPC 5.40 Build 461.1" and "QuickOPC 2016.2 (5.41.524.1) Full".
  • Using .Net 4.6.2 and setting release to mixed works without problems.
  • Using .Net 4.5.2 and setting release to x64 works without problems.

Program used:
using System;
using OpcLabs.EasyOpc.UA;
 
namespace ConsoleApplication1
{
    internal class Program
    {
        private static void Main(string[] args)
        {
            var uaClient = new EasyUAClient();
            var endpoint = new UAEndpointDescriptor(IPAdress);
            var node = new UANodeDescriptor(NodeAddress);
            UAAttributeData result = uaClient.Read(endpoint, node);
            Console.WriteLine(result.Value);
 
            Console.ReadKey();
        }
    }
}

Is .net4.6.2 not yet fully supported or did I run into an unfortunate bug?

Best regards,

Erik
