The one workaround I am aware of is to write a base class in C# that has the necessary attributes and then implement the rest in Python by deriving from that class. If you need to have the base class call the derived class you can add some protected abstract methods that the Python class would override. Certainly not ideal, but it's probably the simplest way to do it for the time being.

The syntax issue is more obvious and we have candidates for classes and methods (e.g. something like __attributes__ = ... for classes, and decorators for methods - harder are attributes on the return type, on the parameters, on fields, etc...). > > At the implementation level the attributes need to be added to the type created by NewTypeMaker. Currently we share the underlying types based upon common base classes & interfaces (and __slots__). We'd need to update this sharing to also take into account attributes and we'd also need to either re-generate methods or wrap the functions we initially generated with an attributed method. Finally to make it truly work the new methods probably need to be declared on the actual type created by NewTypeMaker (today they are either dynamic methods or static methods declared in some other class). > > So there are both a lot of details to get right along with the syntax issues. > Thanks for the reply Dino.
