Pablo, one of our Visual Studio Ecosystem enthusiasts just released a version of IronPython Studio setup that installs with the Integrated Shell.
For those who don't know the difference, we have an isolated shell redist and an integrated shell redist. The isolated shell is separate from Visual Studio while the integrated shell ties in with Visual Studio. If you install a product using the Integrated Shell and then install Visual Studio Standard, Professional, or Team Suite, the Visual Studio extension installed with the integrated shell will just merge with your VS edition seamlessly. On an isolated shell, installing Visual Studio Standard, Professional, or Team Suite will not merge your extension and the product is completed separate from Visual Studio.
With the new setup sample, you can now install IronPython Studio on an isolated or integrated shell. Feel free to use it as an example for your own Visual Studio extensions.
