I am curently running VS2022 Version 17.14.23. Targetting Net8
Although I have purchased previous versions of I have downloaded and installed 2025.v2(740). Doing so knocked out the earlier versions. I can put up with that as I am moving all projects up to Net8. However despite spending hours I cannot get the components to appear in the toolbox, nor in any way drag them onto a form. They do appear grayed out; but even then I think the version is incorrect.
The instalation path base is: C:\Program Files (x86)\MESCIUS\ComponentOne\WinForms\bin
Any assistance appreciated.
Regards

Hello Michael,
This is a breaking change introduced by Microsoft. Starting with .NET 6/8, third-party controls are available only via NuGet packages. Please refer to the following documentation for more details:
https://developer.mescius.com/componentone/docs/win/online-studio/addingnuget
So, if you want to use FlexGrid in your project, you need to add C1.Win.FlexGrid NuGet package from nuget.org to your project.Regards,

Hi,
Thanks for the assist. I just don’t kow anymore if I need the hassle. I’m trying to retire and stuck with a few clients who I don’t wqant to abandon. So I have to decide if I am going to go through the whole nightmare of updating the myriad of components on my development machies or just go and find a good Irish pub.
Regards
Mick
