Minimal example of a StackOverflowException in an OPC UA Server

This example application reproduces a StackOverflowException in an OPC UA Server that is given many asynchronous requests from the same client session.

Running only the server

dotnet run -c Debug -p OpcUaStackOverflowExample.csproj -- server-only

Expected output:

Server started
Stack overflow.

Running only the client

dotnet run -c Debug -p OpcUaStackOverflowExample.csproj -- client-only

Expected output:

Client connected
Received root folders
Unhandled exception. Opc.Ua.ServiceResultException: BadSecureChannelClosed
   at Opc.Ua.Bindings.ChannelAsyncOperation`1.End(Int32 timeout, Boolean throwOnError)
   at Opc.Ua.Bindings.UaSCUaBinaryClientChannel.EndSendRequest(IAsyncResult result)

   at OpcUaStackOverflowExample.Program.<Main>(String[] args)

Run both client and server

dotnet run -c Debug -p OpcUaStackOverflowExample.csproj

Expected output:

Server started
Client connected
Received root folders
Stack overflow.

Running in release mode

To run in release mode change Debug from the previous commands into Release.
