Unable to load plug-in ID Already in Use for DEBUG

Hello everyone. I’ve read all the other discussions about this problem but didn’t manage to solve the problem.
I’m trying to go Debugging using Visual Studio 2022 for a plug-in in Rhino 6.
The problem is that i receive the message on Title of the Topic only if i Run the Debug.
So if I open Rhino normally, delete the plug-in .dll, I can use it and works like a charm. But in this way I can’t debug it. I’ve tried unistalling via CMD and removing all the folders, but nothing again, I still receive the message that the Plug In is already in use.

Can anyone help me to find a solution please?
PS. I could debug this plug-in before, so it can work…

Hi @Samuele_Angeletti,

Are you writing C++ or C#?

For C++, Visual Studio 2017 was required for V6.

For C#, .NET Framework 4.5 was required.

When you get this error, check to see if the plug-in really is loaded using the PlugInManager…

Hello Dale,
thanks for you answer. I’m working on C# and yes the plug-in was correctly installed. Actually that was the problem!
I needed to remove the plug-in from the instance of Rhino 6 and add this line of code:

public override PlugInLoadTime LoadTime => PlugInLoadTime.AtStartup;

In the class that inherits from PlugIn.
Now when i debug the plug-in gets installed byitself correctly.
Anyway this is really strange because in another Computer I can start the debug without this line of code and without removing the Plug-In from Rhino 6…

Anyway I hope that this line of code can help other people to reach a fast solution.
Thanks!
