I am searching for free/opensource .NET SDK that will enable me to write the client that will subscribe to AE server and retrieve evens of interest.

Only free I found is Softing OPC-Classic-SDK found on Guthub.

Are there any other OPC Classic SDK available that are free of charge? There are a lot of them, but very expensive for my use case.

Unfortunately, I am not able to use the new OPC UA specification.

The OPC-F has an implementation that is available to members.

It is free if your company is already a member for other reasons.

Unfortunately, we don't have membership.

Is there any other solution that may fit?
