Hello,

i am using c# asp.net .Net Framework 3.5 with visual studio 2010.
the problem occured when i running my website through the IIS ( not in debug mode ),
and also when i running the website in debug mode.
i think the problem is relevant to the OPC-UA Version that i am using - how can i make sure that my website is using the OPC-UA dll's that in my Bin folder, and not using them from the install directory of the OPC-UA ?

thank you,
Adi Damty

Hello. I am trying to reproduce it. Can you please answer this:
  1. What programming language are you using?
  2. What development environment and version are you using?
  3. Are you running your app from within the development environment (Visual Studio), or do you host it directly in production-grade IIS?
  4. Are you running it with a debugger, or without?

Thank you
