In .NET, in order to take advantage of the functionality provided by OPC Data Client, you need to reference its NuGet packages or assemblies in your own project.
The OPC Data Client NuGet packages depend on other NuGet packages, and they may have further dependencies too, recursively. Each package is licensed to you by its owner. Software Toolbox, Inc. is not responsible for, nor does it grant any licenses to, third-party packages.
The following chapters describe how this is done.
You may also want to review:
Earlier versions of OPC Data Client allowed you to reference the product assemblies directly. With some exceptions (such as for PowerShell or C++/CLI development), this model is no longer supported. If you are upgrading from such earlier OPC Data Client version, remove all individual assembly references to OPC Data Client assemblies, and then reference the NuGet packages instead, as described here and in the related documentation chapters.
