@seghierkhaled Thanks for reply,
And when i removed SuperHelper plugin then extrabuttons bottom and melanoplus work for me fine in Rhino8,
PersistentDataEditor and [QuickConnection]
are opensource in github
I change Sdk nuget.org packeges grasshopper v8.1 to Rhino8 in Visualstudio and rebuild it
But doesn’t work stil!
Do you have any suggestions? Or help because this plugin is very useful and the author won’t answer to fix it! Maybe there is a bug in the Rhino8 sdk?

In food4rhino the plugin already support Rhino8
C:\Users\user\AppData\Roaming\McNeel\Rhinoceros\packages\8.0 >> PersistentDataEditor

Yes! PersistentDataEditor But it doesn’t run as well as Rhino7 for components
And quick-connection doesn’t loaded

Create a shortcut of Rhino8 and call it for example Rhino 8 net

Right click and open properties window
add space + /netfx in the Target like this:

“C:\Program Files\Rhino 8\System\Rhino.exe” /netfx

You can then use all non supported plugins, if you can’t use a plugin you need to ask the developer

Both projects are only built to support net framework 4.8:

If you want to support both net48 and net7.0, you should look at how to set up multiple target frameworks:
