Currently, the solution you are referring only contains examples that have to do with Reactive programming model, and that requires an extra download from Microsoft. I suspect that the missing download is the reason for the problem. If you are specifically interested in the reactive programming, let me know and I will resolve it with you.

But for most purposes, you should work with the examples contained in the QuickOpcCsharpExamples solution instead.

Compilation error UA code in QuickOpcCSharpExample4 was created by a_v_c
Hi all. I downloaded the evaluation tool to check if it is fine for the client I am develepping. I have just generated an example called "QuickOpcCSharpExamples4", and in class _UAItemChangedObservable.Subscribe.Main.cs I am having a compilation error in line number 25:
using (ramp.Subscribe((e => Console.WriteLine(...

Translating the error to English, it says something like this:
"Lambda expression cannot be converted in type 'System.IObserver<OpcLabs.EasyOpc.UA.Generic.EasyUAMonitoredItemChangedEventArgs<float>> because it is not a delegate"

Any help would be appreciated.

Regards
