2. [New issue] How to direct print output to the Console in a windows standalone?
http://ironpython.codeplex.com/workitem/35688
User johntrinder has proposed the issue:

"Hi, 
I didn't know whether this is the correct site for help from the IP community but here goes.

I have a DLL written in C# that opens a Console window inside a Windows app. I am utilizing this for use with IronPython when creating a Windows app as a standalone that needs the Console window along with the other windows.

It works fine doing for eg, Console.WriteLine() but output from the IP print method is not displayed.

How can I tell IP to send output from 'print' to the Console? I'm sure the answer is simple but I'm out of ideas.

Thanks for any help given.

PS I've attached the .cs file if anyone's interested in how it's done (NB. I didn't create the code)"
