PythonNet on Cygwin
by Nikhil Garg 21 Jun '17

Hi Guys, I was wondering if anyone knows how to make Python for .Net work on cygwin installation of python. I have been looking around and find a mixed bag of information. If anyone knows of the working version of Python for .Net and its dependency, I would appreciate if you could share it with me. Currently, I am using a generic windows version and it works just fine, but I need it to work on Cygwin version of python. I appreciate any helpful replies. Thanks, Nikhil

cx_freeze and python.net
by Boris Burdin 22 May '17

22 May '17

Hello everybody, I'm trying to build a python.net application using cx-freeze . Once the application is built, I put in my final folder the Python.Runtime.dll. but it stil doesn't seem to work . Actually, when I run the .exe file, nothing is happening. So, I wonder if there were something else to do, another dll to put in the folder, or any option to use with cx_freeze when building the application ? i would be very grateful if you could help me on this matter .. Thanks in advance, Boris

upcoming talk about pythonnet at PyOhio

http://pyohio.org/schedule/presentation/240/ Saturday 10:30 a.m.–11:20 a.m.Integrating Python into the CLR with Python for .NETHussein Farran <http://pyohio.org/speaker/profile/269/>Audience level:IntermediateDescription Python for .NET is a project dedicated to being able to call into Python from the CLR. Where IronPython has fallen off as the .NET Python prodigal son Python for .NET has picked up the slack. Python for .NET (or pythonnet for short) is an integration of the C Python engine with .NET. We'll be going through the uses and methods of integration of Python with your .NET projects. Abstract This talk covers embedding Python into the .NET runtime as well as running Python from your .NET code. It will be in C# on the .NET side. It will cover topics such as embedding Python, purposes for scripting, script security, and script/embedded code speeds. I will also cover IronPython and provide a comparison and analysis of how it compares with Python for .NET. This may include talking notes about the implementation of IronPython as well as benchmark comparisons. Hussein Farran Hussein Farran is relatively new to the professional IT world, but he’s doing his best to come in blazing. While building his experience Hussein strives to forge connections with those more experienced and to pass on what he knows to those less experienced. As a Software Developer at UseTech Design, Hussein has the opportunity to dip into many project types and to learn from a varied cast of co-workers and mentors.

pythonnet appdomain(s)
by Adam Klein 07 Sep '16

07 Sep '16

Hello, Is there a design reason that pythonnet loads C# assemblies into its own AppDomain rather than establishing a separate AppDomain? It would be useful for instance when developing in C# in parallel with writing python code (say, in the ipython REPL) to be able to reload C# assemblies dynamically. Also, we've found it useful in Initialize() to enable shadow copying, to prevent file locking, ie internal static void Initialize() { ... AppDomain domain = AppDomain.CurrentDomain; // prevent file locking domain.SetShadowCopyFiles(); domain.SetShadowCopyPath(null); Although these are deprecated methods, and really it should be establishing a new AppDomain as above.

"Incorrect" behavior of inheriting from class which is inherited from .Net class
by Hansong Huang 25 Aug '16

25 Aug '16

Hello, This is related to previous investigation of inheriting from .NET interface class to create WPF MVVM structure. As now I believe it has nothing to do with interface class, but instead caused by inheriting from .Net class overall. please see the following code import clr, Systemclass baseNA(System.Random): __namespace__ = "BaseNA" def __init__(self): super(baseNA,self).__init__()# @clr.clrmethod(System.String,[]) def ToString(self): return "string" class baseNB(baseNA): __namespace__ = "BaseNB" def __init__(self): super(baseNB,self).__init__()bna = baseNA()print bna.ToString()print bna._Random__ToString()bnb = baseNB()print bnb.ToString()print bnb._baseNA__ToString()print bnb._Random__ToString() This produces the following outputstringBaseNA.baseNABaseNB.baseNBBaseNB.baseNBBaseNB.baseNB as you see, while baseNA -- the first level inherited class works fine. ToString() overrides System.Random.ToString() But baseNB inherited from baseNA did not inherit ToString() method from baseNA, but rather inherited from System.Random. Not sure if it is a bug in python.net or was intended. regards, Hansong

Update License - MIT
by Denis Akhiyarov 02 Aug '16

02 Aug '16

We are in the process of updating pythonnet library to MIT license and asking for permission from all past contributors to change the license from legacy Zope Public License Version 2.0 to MIT license. Please see discussion here: https://github.com/pythonnet/pythonnet/issues/234 If you think that you are past contributor and not listed there, then please reply in this github issue. I identified two people from sourceforge history who are not listed in github history: @hardcoded and @jfrayne (Joe Frayne) Not sure who @hardcoded is? Brian, do you have the history before 2006? If not, then we have to assume that you are the only contributor before migration to sourceforge in 2006. Thank you, Denis
