Installation

Install the Client Package

The simplest way to get started is to install the top-level client package:

dotnet add package OpcSharp.Client

This pulls in all layers of the stack.

Individual Packages

If you only need specific layers, reference them directly:

OpcSharp.EncodingBinary encoder/decoder for all OPC UA types
OpcSharp.TransportTCP transport, Hello/ACK, chunking
OpcSharp.Transport.HttpHTTPS/WebSocket transport

dotnet add package OpcSharp.Transport
dotnet add package OpcSharp.Transport.Http
dotnet add package OpcSharp.Security
dotnet add package OpcSharp.Protocol
dotnet add package OpcSharp.Services

Target Frameworks

OpcSharp targets multiple frameworks:

  • netstandard2.0 — broadest compatibility (.NET Framework 4.6.1+, .NET Core 2.0+, Mono, Xamarin)
  • net8.0 — LTS release with ECC security policy support and certificate generation
  • net9.0 — current release
  • net10.0 — preview support

Features like ECC security policies and self-signed certificate generation require net8.0 or later.
