First steps with Python.NET

[burque505]

I have run into problems with PythonNET recently following the upgrade from C# 8 to C#9 (I think). I've had this error code pop up (actually in other C# projects as well):
 

Code:

Copy      Help

System.PlatformNotSupportedException: BinaryFormatter serialization and deserialization have been removed. See https://aka.ms/binaryformatter for more information.

I believe there were severe security issues with the BinaryFormatter that resulted in it being removed. At the moment, I've simply been deleting references to 'PythonEngine.Shutdown()' from @Gintaras's class, and the error goes away. I still use the following, however:
 

Code:

Copy      Help

PythonEngine.Initialize();
using (Py.GIL()) {
   // do stuff
    
    dynamic scope = Py.CreateScope();
  // do stuff with scope
    Py.GIL().Dispose();
}

@Gintaras may have a better way to do this, of course.
