[IronPython] Python Tools for Visual Studio

Thu Mar 10 22:03:17 CET 2011

This is great! First reports:

1. The installer refused to work until I completely removed IronPython
- not just the VS tools (I'm okay with this, I tend to use repo builds
of IronPy anyway.)

2. I love that it detects my Python installs (though apparently not my
IronPython 2.6 install?) and including all files by default is far
more robust than it was back when I complained about it.

3. Opening a .py file caused a crash in Microsoft.PythonTools.Analysis
(submitted through WER): 'key "__next__" was not found'. This is
apparently due to my file being for Python 2.7 but the default
interpreter being Python 3.2. (Obviously using a project with the
right setting fixes this.)

4. I was unable to build the code in the repository (from the VS 2010
command prompt, x86 tools, latest VSSDK installed). I've attached the
entire msbuild output, the command line I used is below and the
warning/error output is below that.
