Rhino crashes when CreateRhinoDockBar is called

I’m currently trying to run our plugin in Rhino 8 WIP. This works fine when I set the .NET runtime to be the .NET Framework, but just crashes the whole application when the runtime is NETCore.

I can reproduce this with a simple plugin (C#, .NET Framework 4.8) that creates a dock bar in OnLoad:

var mRhinoUiDockBar = new RMA.UI.MRhinoUiDockBar(
    Guid.NewGuid(), "DockBar", new Panel());
    this, mRhinoUiDockBar, false, 
    new System.Drawing.Point(0, 0));

Is the crash expected here? Could this be fixed or improved to throw a meaningful error that can be handled?

Then I have another question, is it possible to set SetDotNetRuntime from RhinoCommon?
I’m checking the current runtime via System.Runtime.InteropServices.RuntimeInformation.FrameworkDescription and try to set the runtime via RunScript in case it is the wrong one, but I guess I’m doing something wrong here:

Rhino.RhinoApp.RunScript(“_-SetDotNetRuntime Runtime=NETFramework”, true)

The command is not correctly executed, it just prints “Command: _-SetDotNetRuntime” in the command line but doesn’t change it.

Thank you in advance and best regards
