[Ironpython-users] struggling with Intellisense and GAC

[George Nychis]

Hi Andy,

Thanks so much for your response.

The issue turned out to be something fundamental... my DLL was built as
"x64" and not as "Any CPU" (even though I was explicitly using 64-bit
ironpython).  As soon as I switch to "Any CPU" the intellisense started
working in the base cases!

I've now been struggling with another Intellisense related issue that I
think might be driven by IronPython using old-style Python classes?

In my C# code, assume I have a class "CSharpTest(string first, string
second)" that I want to inherit from my Python class AND I want the Python
class to not require parameters (i.e., it will explicitly call the
CSharpTest constructor)... I believe I have to do the following:

########################################
class Child (CSharpTest):
    def __new__(cls):
        instance = CSharpTest.__new__(cls, "one", "two")
        return instance
#########################################

The issue seems to be that "instance" is of unknown type, which I think is
driven by old-style classes.  Am I doing inheritance the proper way here?

So when I go to do:
    c = Child()

"c" does not seem to have any Intellisensable class members, and I believe
this is because its type is unknown.

Is my understanding correct that this is due to old-style classes?  Or
might I be missing something else?
