Creating buttons on a tab in .NET 8.0.

[rhavrys]

Can anyone suggest how to load an icon onto a button in .NET 8.0 if PresentationCore is missing?

I would assume that the code is virtually unchanged from the previous .NET Framework. What do you need PresentationCore for?

[rhavrys]

PushButton pushButton = CreatePushButton(panel0, typeof(CmdAbout), "About");
pushButton.LargeImage = Converter(Properties.Resources.about_32_32);
pushButton.Image = Converter(Properties.Resources.about_16_16);

For example, LargeImage & Image its presentation core. When I try to set an icon for my buttons, I get an error that PresentationCore is missing. Unfortunately, I couldn't find any answers online on how to do this.

Can WPF also be used to create UIs in .NET 8? I heard there were some changes to it as well.

Image and LargeImage are Revit API properties on the RibbonButton class:

They are of type ImageSource:

You can certainly convert to that in .NET Core as well:

Yes, of course, squared.
