@filmor If I understand this correctly, one wouldn't even need the dynamic.py script anymore for DynamicObject access to work, correct? That seems great :)
To test this in our setup, can you point me to a wheel that I can install, or provide documentation how to build it?

@spkl Yes, the dynamic support would be integrated. To build a wheel, the simplest way is to get uv and the .NET SDK installed on your machine, check out the repo and run uv build. That builds the wheel in dist/.

OK so I did a little digging and found out that I can pip install . in the root directory of the pythonnet repository to install this version into my venv.
Edit: Is this wrong? Should I try again with uv?

Getting the value of dynamic properties seems to work, but I encountered a problem when setting dynamic properties. This is what I observed when running a script like this:

x = obj.MyProp
obj.MyProp = None
y = obj.MyProp

For line 1, TryGetMember is called for name "MyProp" and x will correctly be assigned the value returned from there.
For line 2, TrySetMember is NOT called.
For line 3, TryGetMember is NOT called, y will be assigned the value from line 2 (None), but that value is unknown to the .NET implementation.
