How can I make CTP in .Net 6.0 project by using Excel-DNA 1.6.0?

You need to fiddle with the clas declaration, to add an explicit interface. See this discussion https://groups.google.com/g/exceldna/c/onRDZLJwoBY/m/ddsjBDbsBAAJ

thanks a lot!

In Net framework 4.8 project, i can use wpf usercontrol onto CTP. Is there any solution to use WPF controls on CTP?
Seems no library support both winform and WPF, except for Net framework, right?

WPF works the same under .NET 6 as under .NET Framework. You need a host control from WinForms to put the WPF into a CTP.

I know ElementHost in WinForm. However, I cannot create a WPF UserControl in WinForm Library project as in Net Framework project.
If I create a WPFLibrary project, I don't know where to find WinForm usercontrol for CTP. Which kind of Library project I should to use? What kind of references I should to add?
Thanks a lot!

After putting <UseWpf>true</UseWpf> in csproj file, I can add WPF usercontrol to project of WInform Library.
