.NET Based OPC UA Client SDK

The .NET based OPC UA SDK supports you in writing .NET OPC UA Clients. The Client SDK is also available as bundle with the Server SDK.

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. When buying the Client SDK, you will receive a license for the Base Library and the Client Library.

The SDK supports .NET Framework 4.8 and Standard 2.1 (Core3.1) and comes with examples as Visual Studio 2019 project files including simple to use NuGet packages. Since SDK v3.2 we support also the new .NET 6.

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) and .NET 6 can run on Windows and Linux.
