Thank you! That asnwered to all of my questions - after loading the
executing assembly into the python runtime I was able to run "from
namespace import *" and that did the job.
About the interop: wow that's really good. Never thought DLR team could
make it that fast.

To expose a whole namespace the simplest way is probably to call
scriptRuntime.LoadAssembly(some_assembly); All of the public types
will then be available for importing from IronPython. That means they
won't all be available at the top-level. If that's not ok you could
use reflection and call DynamicHelpers.GetPythonTypeFromType(...) and
inject all the types you want.
As for interop the performance should be fine. When using dynamic
from C# the overhead should basically be similar to the overhead of
calling a function within Python. And for Python calling into C# the
overhead is the same as any Python code calling into any of the
runtime -- in other words pretty darn fast. For a simple function
call to a Python function last I measured I believe it was around 40
instructions on x86 to perform the call.
For example on my laptop this runs in about 1/3 of a second and
performs 10 million function calls:
import time
def f():
def g(): pass
for i in xrange(10000000):
g()
s = time.clock()
f()
e = time.clock()
print e -- s
So what probably matters a lot more is what the function is doing.

Salut, fellow coders!
I have an application where i need some live coding to debug and use
it. I've been coding in C# for ages now.
I looked into different languages, and found python. And obviously
fell in love.
Now i have a home-made interactive python console with my application.
I implemented suggestions with dir() and so on.
tldr:
The problem im facing is that I need to integrate whole application
with the console now. I know I can expose types and variables thru
scope.SetVariable but what I need is to expose a whole /namespace/ to
the scope.
Any help would be appreciated.
P.S. How fast is interop between python and C#? Would it be ok to have
a python function as dynamic in C# and calling it about 250 times a
second?
Thanks,
Iivari Mokelainen
