Details

When instantiating a C# class in a Python module, two C# objects are created:

C# class:

classSomeClass{publicSomeClass(){}publicSomeClass(intarg1,stringarg2){}}

Python module

obj=SomeClass()

The default constructorSomeClass() is called twice inMetaType.tp_call , first byusing NewReference obj = NativeCall.Call_3(tp_new, tp, args, kw); and then bytype.Init(obj.Borrow(), args, kw).

If Python does this:

obj=SomeClass(1,"str")

Thenusing NewReference obj = NativeCall.Call_3(tp_new, tp, args, kw); calls the default constructor and thentype.Init(obj.Borrow(), args, kw) calls the one with arguments.

Is this an expected behaviour? Is there a workaround or fix for this? I am working with a case where I really don't whant the constructor to be called twice.

Is this related to#495?

Thank you in advance.
