How can I fix missing IronPython project templates in Visual Studio 2010?
I had a similar issue with IronPython 2.7 RTM on VS 2010 SP1. I had the python tools for VS 1.0 installed before I installed IronPython. I did the following to resolve the issue

Uninstalled IronPython
Uninstalled Python tools for VS
Installed IronPython 2.7 RTM without the "Tools for VS" feature, this is provided by the python for VS installer
Installed Python Tools for VS
I installed IronPython yesterday.  After running Visual Studio the IronPython project template showed up but later it was gone.  I've tried repairing, uninstalling, and reinstalling without fixing the issue.  How can I make the templates show up?
