[Ironpython-users] Loading python compiled with clr.CompileModule

[Josiah Kiehl]

I'm trying to execute this example code:
https://stackoverflow.com/questions/32639893/call-dll-function-from-c-sharp-ironpython

I realize the posted question is a few years old at this point... has
something changed in how python, compiled to a DLL via clr.CompileModule,
is loaded?

I'm getting this error when I run the code in the example at the above link:
Unhandled Exception: System.TypeLoadException: Could not load type
'System.Runtime.CompilerServices.Closure' from assembly 'System.Core,
Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089'.
   at DLRCachedCode.test$1(CodeContext $globalContext, FunctionCode
$functionCode)
   at IronPython.Compiler.OnDiskScriptCode.Run()

(full stack:
https://gist.github.com/capoferro/5a730088582b8cd36591be510d6ca2fc)

My ipy.exe, which did the compilation, is 2.7.8.0 and my embedded
IronPython is 2.7.8.1, though I get the same error on 2.7.8.0.

Am I missing something obvious or is there a better example to use?

My end goal is to be able to take a python module defined in a file
(foo.py) with some functions defined, compile it into a dll via
CompileModule, then load it directly from the dll via ImportModule to skip
the performance hit of interpreting the Python at runtime.

Thanks!
Josiah
