.NET Based OPC UA Client/Server SDK
Software Requirements

The OPC UA .NET SDK is built with Microsoft .NET Framework 3.5 SP1, .NET Framework 4.0 SP1, .NET Framework 4.5 and .NET Core 2.0.

During installation on windows systems, you can choose between the following four varieties of the SDK

  • Microsoft .NET Framework 3.5 SP1
  • Microsoft .NET Framework 4.0 SP1
  • Microsoft .NET Framework 4.5
  • Microsoft .NET Core 2.0

Depending on what you choose, the setup will install Visual Studio 2017 project files and pre-built applications matching you choice. The Visual Studio projects for .NET Core are built for .NET Core 2.1. .NET Core 2.0 is end of life, so we do strongly recommend to use .NET Core 2.1 instead of .NET Core 2.0 as target framework.

However, independent of your choice, Nuget packages including all supported versions can be found in [Installation Directory]/packages. It is possible to install another version of .NET Framework, change the settings in the Visual Studio Project and build against this .NET Framework.
