I am currently in the very early stages of implementing opc features into our system and I do need to play around a bit to get familiar. From what I've gained so far I feel QuickOpc will certainly satisfy our ultimate needs, but I do want to see things from the server perspective as well.

The trial version (what you are using now) is identical to what you get when you buy it, except that the trial version only provides "good quality" data for the first 30 minutes the client application process is run (it can be re-started to get another 30 minutes, and so on).

As we have developed it just for test and demonstration, there are no configuration features.
For OPC "Classic" servers as this one, it is the Microsoft COM/DCOM infrastructure that takes care of starting and sometimes also stopping the server(s). The actual way it works depends on how the server is developed and how COM/DCOM is configured. In the case of our server and how it is normally installed, COM starts it with the first OPCServer object being created inside it by any client, and it stops itself automatically several after no live OPC objects exist inside it (i.e. is not used by any OPC client).

For OPC Unified Architecture (that's in the example projects that start with "UA"), we do not install a sample server, but instead provide a publicly accessible OPC-UA server on the Web, and again, all examples refer to it. The server's URL can be seen in the code of those examples.

If I may, another question is where does the datagenerating opc server reside, since obviously there must be one to answer the query of ConsoleApplication1?

thank you for your interest in our products.
I think that the behavior you described has nothing to do with our product. It has to do with Visual Studio. The solution contains some projects that are Web pages, and Visual Studio starts an internal Web server for them. VS treats the solution as a whole, and thinks that somehow these Web sites may be needed e.g. when you debug "ConsoleApplication1".
If that bothers you, simply unload (or remove... but that's maybe too much) the Web projects from the solution.

Is it possible to shed some light here?
Best regards,
