Note (1): This functionality is not directly available on the development platform, but can be achieved by combining with VBA code (through COM platform).

Note (2): On Windows only.

Note (3):

In runtime, all user interface features (such as controls, dialogs, and live binding; Windows Forms and WPF) and nonvisual components are supported both under .NET Framework and .NET 6+. However, "designing" them (this includes tasks like dragging from the Toolbox, or configuring in Properties window) in Visual Studio is only possible in .NET Framework projects. In order to achieve visual design for .NET 6+ projects, the developer can make two project files over the same set of source files, one targeting .NET Framework and one targeting .NET 6+, and use the project that targets .NET Framework for visual design tasks.

 

OPC Studio attempts to hide the differences caused by different implementations on various platforms and runtimes from the developer who uses it. It is not, however, always fully possible.

Throughout the documentation, we also try to pinpoint specific areas which are not available under some development platform or may work differently. There may be other, subtle differences under each platform as well. For example, the types of inner exceptions generated by the component may differ under various .NET 6+ runtimes versus the code running on .NET Framework, unless the type of exception is documented. The error messages and other details of exceptions may differ as well.

The features discussed here, or some of them, may not be available in all editions of the product. Check the Product Editions page for differences between the editions. The trial license has all features enabled (and is limited in period for which it provides valid data), but licenses for specific commercial editions may have functionality limitations.

'Support' means that a member of OPC Studio product family is designed to work and tested on the environment, and vendor's technical support may be contacted for assistance with that OPC Studio product family member on the environment. Support may be not available for operating systems, .NET runtimes and other dependencies that are past their active lifecycle at the time of support request, even if they were supported at the time of product release.
