i'm novice @ opc , i'm making opc client on c#, , testing @ matrikon opc server. , have question, how shutdown connection server when program made it's business ? cause notice when i'm finishing program it's still anyway marked active client in matrikon opc server. tried delete subscribe tags , delete created group, it's doesn't work.
the best use sample code , .net api opc foundation:
https://opcfoundation.org/developer-tools/developer-kits-classic
the api free registered users (for source code , other need member).
the opc .net api uses disposable pattern, connections/subscriptions etc. clean correctly.
