QuickOPC is a suite of OPC Client/Subscriber Development Components for COM and .NET. These components are for OPC "Classic" (COM/DCOM-based), OPC XML-DA, and OPC Unified Architecture (including OPC UA PubSub) specifications.
QuickOPC is a commercially licensed product. Without a license key, it runs in a trial mode. The trial provides valid data to client or subscriber applications for 30 minutes; after that period, the component (your app) needs to be re-started, and so on. You must also comply with licensing terms for 3rd-party material redistributed with QuickOPC. For details, see the documentation.
Remember that NuGet is primarily a tool for resolving build-time dependencies. The amount of functionality that you get through QuickOPC NuGet packages is smaller than what QuickOPC can actually do for you. If you want a full coverage of the features, you would be better off downloading the Setup program from OPC Labs Web site. Further below you will find a list of differences between the two distribution forms.
QuickOPC requires .NET Framework 4.7.2, .NET Core 3.1 or .NET 6.0 as a minimum. Under .NET Core and .NET 6.0+, it is supported on Linux, macOS and Microsoft Windows.
PLEASE DO NOT USE PRE-RELEASE PACKAGES UNLESS INSTRUCTED TO DO SO.

How to start
If you do not mind reading the documentation: Getting Started. Or, the whole User's Guide.
Otherwise, just instantiate one of the following objects (depending on the OPC specification), and explore its methods:
OpcLabs.EasyOpc.DataAccess.EasyDAClient(for OPC DA, OPC XML-DA)
OpcLabs.EasyOpc.AlarmsAndEvents.EasyAEClient(for OPC A&E)
OpcLabs.EasyOpc.UA.EasyUAClient(for OPC Unified Architecture)
OpcLabs.EasyOpc.UA.PubSub.EasyUASubscriber(for OPC UA PubSub)
using OpcLabs.EasyOpc.UA; ... var client = new EasyUAClient(); object value = client.ReadValue( "opc.tcp://opcua.demo-this.com:51210/UA/SampleServer", "nsu=http://test.org/UA/Data/ ;i=10853");
Using the example packages
In order to run the code from console-based example packages, you need to call it from your project. The examples are organized by the OPC specification, and each example is a static method that you can directly invoke. For easier exploration, there are also methods that provide the user with a menu of methods to choose from.
For OPC Alarms&Events examples, call method:
For OPC Data Access examples, call method:
For OPC XML-DA examples, call method:
For OPC Unified Architecture examples, call method:
For OPC UA PubSub examples, call method:
Alternatively, you can call just a single selected example, e.g. for reading
an OPC UA node, call the
