Hi
We have some existing .NET applications and would like to be able to read and write WinCC OA Datapoints and also connect for change notifications.
What is the recommended way for doing this?

Re: .NET applications
Hi Mark,
ask your key account manager, as far as i know a native WinCC OA .NET API is under construction ...
Some time ago i connected C# to WinCC OA by Webservices (REST,JSON), the webservices are implemented in WinCC OA Ctrl... but i didn't continue with that...

Maybe Apache Thrift would be a better approach for that.
https://thrift.apache.org/
It depends what you need, if you need a .Net client without installing OA, then Webservices are an option. If you need max. performance then a native API will be better...
For example I implemented a native API for Java to connect to OA values for database logging...
