[IronPython] clrtype: How to subclass ClrClass?

Fri Mar 12 18:56:49 CET 2010

Hi Lukas, the clrtype fix for http://ironpython.codeplex.com/WorkItem/View.aspx?WorkItemId=26249 is indeed in in 2.6.1.

About this Silverlight error, I am not sure. Including the mailing list in case someone else can help.

error CS1685 : Warning as error : The predefined type 'System.Runtime.InteropSe

rvices.DefaultParameterValueAttribute' is defined in multiple assemblies in the

 global alias; using definition from 'c:\IronPython_Main\Src\Runtime\Microsoft.

Scripting.Core\Stubs.cs'

Done Building Project "C:\IronPython_Main\Src\Runtime\Microsoft.Scripting.Core\

Microsoft.Scripting.Core.csproj" (default targets) -- FAILED.

Unfortunately I am unable to build IronPython for Silverlight. Is it currently broken or do I do something wrong?

Hi Shri,
I have built IronPython Main (I should have known it is so easy :-) and I verified the fix works for me there. I hope it will get into 2.6.1. Thanks.

Hi Shri,
I haven't tried to build IronPython from source yet and I do not have time to test it now (maybe it's easy - I don't know). But I saw the fix is checked in, so I wait for your next build, try it there and let you know.

Thanks a lot.

Hi Lukas,

I have attached a patch to the bug. If you build from source, you can get the fix. I will also check if we can get it into 2.6.1 or not, but I need to chat with Dino about how impactful the change is

Sorry, I have not, and unfortunately will not be able to get to it until next week. Please vote on http://ironpython.codeplex.com/WorkItem/View.aspx?WorkItemId=26249 if you want to see it fixed in 2.6.1. Depending on the fix, it might have to wait until after 2.6.1

Hi all,

it looks like I cannot subclass a class based on ClrClass metaclass:

IronPython 2.6 (2.6.10920.0) on .NET 2.0.50727.4927

Type "help", "copyright", "credits" or "license" for more information.

import clr

import clrtype

class Product(object):

... __metaclass__ = clrtype.ClrClass

...

p = Product()

print "CLR type name: %s" % p.GetType().FullName

CLR type name: Product

class MyProduct(Product):

... pass

...

Traceback (most recent call last):

File "<stdin>", line 1, in <module>

KeyError: The given key was not present in the dictionary.

Is it a bug or am I doing something wrong? Thanks.

Hehe, I ran into this a couple of days ago on Silverlight as well.

All the best,

Michael
