OPC UA .NET Standard — meta-package

OPCFoundation.NetStandard.Opc.Ua is a convenience meta-package that brings in the standard OPC UA .NET Standard stack components in one reference. It does not contain any types of its own; install it when you want the curated default set of packages an OPC UA application typically needs.

What you get

The meta-package depends on:

  • OPCFoundation.NetStandard.Opc.Ua.Types
  • OPCFoundation.NetStandard.Opc.Ua.Core.Types
  • OPCFoundation.NetStandard.Opc.Ua.Core
  • OPCFoundation.NetStandard.Opc.Ua.Security.Certificates
  • OPCFoundation.NetStandard.Opc.Ua.Configuration
  • OPCFoundation.NetStandard.Opc.Ua.Client
  • OPCFoundation.NetStandard.Opc.Ua.Server
  • OPCFoundation.NetStandard.Opc.Ua.Gds.Common
  • OPCFoundation.NetStandard.Opc.Ua.Gds.Client.Common
  • OPCFoundation.NetStandard.Opc.Ua.Gds.Server.Common
  • OPCFoundation.NetStandard.Opc.Ua.SourceGeneration

Pick individual packages instead of the meta-package when you want a tighter dependency surface (e.g. client-only or server-only applications).

Getting started

using Opc.Ua;
using Opc.Ua.Client;
using Opc.Ua.Configuration;

// Open a session to an opc.tcp server.
var application = new ApplicationInstance(telemetry)
{
    ApplicationName = "MyClient",
    ApplicationType = ApplicationType.Client,
};
await application.LoadApplicationConfigurationAsync(silent: false).ConfigureAwait(false);
await application.CheckApplicationInstanceCertificatesAsync(true).ConfigureAwait(false);
