Python Tools for Visual Studio turns Visual Studio into a Python IDE. It enables developers to use Visual Studio's productivity features to build Python code using either CPython or IronPython and adds features like scaling code on HPC clusters. IronPython is an implementation of Python that runs on .NET and Mono frameworks. It supports an interactive console and makes .NET libraries available to Python while maintaining compatibility. There is tooling integration with Visual Studio. IronPython can be used for scripting .NET applications. Code examples demonstrate loading an XML file and creating a WPF application. Dynamic types allow IronPython code to be used from C#.

- 1. Python with DotNet and VS2010
- 2. Python tools for VisualStudio2010 http://pytools.codeplex.com/
- 3. Python Tools for Visual Studio turns Visual Studio into a Python IDE. It's a free & open source plug-in for Visual Studio 2010 from Microsoft's Developer Division. PTVS enables developers to use all the major productivity features of Visual Studio to build Python code using either CPython or IronPython and adds new features such as using High Performance Computing clusters to scale your code.
- 4. IronPython http://ironpython.codeplex.com/ Latest version 2.7.1
- 5. IronPython is an implementation of the Python programming language running under .NET / Mono and Silverlight / Moonlight . It supports an interactive console with fully dynamic compilation. It's well integrated with the rest of the .NET Framework and makes all .NET libraries easily available to Python programmers, while maintaining compatibility with the Python language. There also is Visual Studio tooling integration. IronPython is an open source project freely available under the Apache License v2.0. The sources are stored on GitHub as part of the IronLanguages project.
- 6. Usage Use IronPython as scripting of DotNet
- 8. Code example that adds reference
- 10. d = XmlDocument() d.Load('load.xml') n = d.SelectNodes('//Puzzle/SavedGames/Game/@caption') for e in n: print e.Value
