.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 Framework 4.6.1.

During installation, you can choose between the following three varieties of the SDK

  • Microsoft .NET Framework 3.5 SP1 and Microsoft Visual Studio 2008 SP1
  • Microsoft .NET Framework 4.0 SP1 and Microsoft Visual Studio 2010 SP1
  • Microsoft .NET Framework 4.5 and Microsoft Visual Studio 2012 Update 2
  • Microsoft .NET Framework 4.6.1 and Microsoft Visual Studio 2015 Update 1

Depending on what you choose, the setup will install Visual Studio project files and pre-built applications matching you choice. This means if you choose the combination .NET Framework 3.5 SP1 and Visual Studio 2008 SP1, the project files for this version of Visual Studio will be installed to [Installation Directory]/examples, and example applications built with .NET Framework 3.5 and the matching assemblies to [Installation Directory]/bin.

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