Thank you for update. I am glad it works now.

I think the cause was what I suspected - it was the "boxing" feature. It is nice in that it greatly simplifies the installation and reduces dependencies. But under the hoods, it needs to do a tricky stuff to hook into Windows APIs, and that might be considered harmful by some security software. In anticipation of that, we have the documentation/knowledge base articles you have referred to correctly.

Best regards

First of all, thank you for the reply!

Secondly, I wasn't able to reproduce the error in a sandbox with the code I provided in my post originally. So I updated my post with code that does reproduce the error.

For future readers:

I went here and saw that I needed install (3) things: Microsoft Visual C++ 2015 Redistributable, OPC Core Components 3.00 Redistributable, and OPC UA Certificate Generator utility. I installed all 3:


I added the <appSettings /> from here (it didn't work until I did this).

After doing all that the error went away. I haven't tested it end-2-end with a real server, so I don't know if it's completely working, or not.

I haven't met this problem specifically, but from the symptoms of it, this may help:

Using OPC causes BitDefender to kill executable was created by WordsLikeJared
Here's some example code:
var client = new EasyDAClient();
 
client.SubscribeItem("", "OPCLabs.KitServer.2", "Demo.Ramp", 10);

Suppose this code is being ran by A.exe. When A.exe is ran and
client.SubscribeItem
is called, BitDefender will kill the A.exe process. BitDefender says it detected a threat. I've gotten IT at my work to allow A.exe to keep running. However my concern is that when we have A.exe running inside our customers' environments their anti-virus and related software may interfere with A.exe running.

Any idea what is causing this or how to prevent this from happening?
