The OPCLabs stuff is shown as "not available in this source"

This was a fresh install of the latest Visual Studio 2022 download, as well as your package.

Hello,

if you expand the project References, and also do "Manage NuGet packages", does it show any errors associciated with the packages? If things are OK, it should like like on the picture below (the build number at the end may differ).



And, if you do Rebuild, can you place here a copy of the possible errors from the Output tool window?

Regards

Just installed .net framework 4.80, still does not work.

Yes, I have .net framework 4.7.2 installed in Visual Studio

Hello.

Do you have .NET Framework 4.7.2 (or 4.8 /4.8.1) Targeting Pack installed (in Visual Studio Installer)?
QuickOPC VS Designer support is currently only for projects targeting .NET Framework (4.7.2+).

Regards

Trying to create a simple VB program to read and write OPC tags from a Kepware server.I have installed the latest Visual Studio, Version 17.9.3 from scratch, .NET 8.0. I downloaded and installed OPC Studio 2024.1.The compiled demos work OK, ran the easyOPCNetDemo and was able to connect to OPC server and read values. However, none of the examples will load and run correctly in Visual Studio. Attached files show errors when trying to load the C:\Program Files (x86)\OPC Labs OPC Studio 2024.1\Examples-NET\VBNET\VisualStudio\QuickOpcVBNetExamples.sln example. If I try and follow the help directions to create a VB forms based app the OPC tools do not show up in the toolbox.
