When accessing a .NET function using PythonNET, if a kwarg is incorrect or doesn’t exist, it is discarded by the PythonNET execution engine

If I have a .NET function like this:

PublicFunctionSomeFunction(nameasString,ageasString)asStringReturn $"{name} - {age}"EndFunction

And I call it in PythonNET like this:

if__name__=="__main__":name="John"age="3"SomeFunction(name,age=age,fake_arg="something")

The fake arg is discarded, and no error or exception is thrown. Python compiles as if the additional kwarg were not there. In this situation, normal Python would be throwing a TypeError.

This is an issue with a multiple kwargs in the methods/functions is that a user can easily misspell and result in unexpected behavior.
