porting C++ CLR .NET framework Winform to .NET 8

we have a tool that was written in C++ CLR where its forms where also written as a Winform in C++ CLR, we plan to upgrade it to .NET 8 but it seems there is a pretty huge shift between .net framework and .NET 8 and/or future versions like 9.
So I am assuming that the way to do this will be pretty tedious. so here are my questions

  1. in the unified .NET version (5 or higher), I assume the only way to create winforms is thru C# and there is no longer support for C++ CLR winforms?
  2. does that mean that I need to recareate the forms, dialogs and controls form my C++ CLR projects in C# and they cannot be reused?

Is there any other way or is it the only way and I cant use my forms, dialogs and user control anymore?

.NET
.NET
Microsoft Technologies based on the .NET software framework.

    Hi, @cebuhax0r

    Please refer to my answer from similar thread: .net8 windows form design view problem

    The out-of-process designer is not compatible with C++ CLR and .NET 6 or later , you need to add the control code manually.
    Also , you need to modify the dependencies as I mentioned in the link.
