Using the sample packages (NuGet)
The sample packages do not contain any executable code (assemblies) by themselves. They just extend your project by adding references to Connectivity Software packages, and include the source code of the examples. By adding the sample package to your project, you get access to the source code of all the examples contained in the package. You can then view the examples, write a code that calls them, or copy-paste code snippets from the examples into your code.
In order to run the code from console-based example packages, you need to call it from your project. The examples are organized in folders by the communication protocol and type of application, 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 client examples, call method: DocExamples.AlarmsAndEvents.AEExamplesMenu.Main1
For OPC Data Access client examples, call method: DocExamples.DataAccess.DAExamplesMenu.Main1
For OPC XML-DA client examples, call method: DocExamples.DataAccess.Xml.XmlExamplesMenu.Main1
For OPC UA client examples, call method: UADocExamples.UAExamplesMenu.Main1
For OPC UA PubSub subscriber examples, call method: UADocExamples.PubSub.PubSubExamplesMenu.Main1
For OPC UA server examples, call method: UAServerDocExamples.UAServerExamplesMenu.Main1
For Sparkplug host application examples, call method: SparkplugDocExamples.Consumer.ConsumerExamplesMenu.Main1
For Sparkplug edge node examples, call method: SparkplugDocExamples.EdgeNode.EdgeNodeExamplesMenu.Main1
Alternatively, you can call just a single selected example, e.g. for reading
an OPC UA node, call the UADocExamples._EasyUAClient.Read.Main1 method.
