Hello,
so far I was not able to reproduce the problem.

I suspect, however, some kind of mixup in assembly/package references. Can you please check that you do not have some additional UA-related assemblies or NuGet packages referenced?

If you do not find anything suspicious, can you send me your .csproj file? Either post it here, or, if it is confidential, email to support09 (at) opclabs.com?

Many thanks

1. It continues to run however none of the nodes are acquired.

2. I've ran examples from the user guide completely fine in a different solution.

3. Yes I believe so, OPCLabs QuickOPC 2023.1

4. I never ran the program on the old version as it had many errors

5. Windows Forms App

Hello.

Can you please provide some additional information?

1. Is your program able to continue normally after the exception is thrown (i.e. it is handled somehow), or is the exception unhandled?

2. Have you tried to open projects (for OPC UA) from the example solutions, and run them (if not, please do so) - do they also have the same problem?

3. Have you been using a previous version of QuickOPC on the same computer before?

4. If so, is it so that the same program has worked with earlier version but now it does not? Or is this a new program, only tested with this new QuickOPC version?

5. What type of project is your program? (e.g. console app, Windows Forms app, Web app, Web service, Windows service, ...)

Thank you

Hello,
I'm modifying a program that uses QuickOPC. Every time I run the code, a System.MissingMethodException is thrown(pasted below). The code is supposed to subscribe to multiple Nodes. I'm currently running on a evaluation license for QuickOPC Ultimate.
