.NET Based OPC UA Client Server and PubSub SDK/Toolkit

Write your own OPC UA Server in C#/.Net

The UA SDK consist of three assemblies that support you in writing .NET OPC UA Servers and Clients including with PubSub functionality. The UA SDK actually consists of three Libraries, the C# Base Library, C# Server Library and C# Client Library. The Base Library contains the native UA Stack and supports the UA Binary protocol and web service binding.

The .NET based Client Server and PubSub SDK is an extension (Add-On) Package that comes together with the .NET based OPC UA Client Server SDK. See the Client Server SDK product page for more information.

The SDK supports .NET Framework 4.8 and Standard 2.1 (Core3.1), .NET6, .NET8 and comes with examples as Visual Studio 2022 project files including simple to use NuGet packages.

The pre-built SDK binaries are pure .NET assemblies which means they can be used on any processor architecture supported by the .NET Framework. The SDK assemblies for .NET Standard 2.1 (Core 3.1), .NET6/8 can run on Windows and Linux.

Free UaModeler for  implementing CompanionModels and code generation included !
