Hello,
I would like to set up OPC UA redundancy on two C # servers ("Non Transparent" and "Hot").
Cannot find documentation on this topic.
Should we put information in Config.xml?
Do we have to manage the code in the C # Server to create the nodes?
How to do ?
Thank you for your answers.

The C# samples do not have the back-channel communication needed to implement a true redundancy pair.
You could develop a C# server that acquires data from a downstream system. It would then be possible to launch multiple copies of this server that has an identical address space but you would need to add logic to handle load balancing and fail over.
In particular, you would need logic to set the SeviceLevel to indicate which is the primary and which is the standby
