The package manger console in visual studio is capable of far more than just adding and removing nuget packages.
It is in fact a full powershell scripting environment with direct access to the Visual Studio IDE Management Api.
This is not just read-only:
$dte.StatusBar.Text = “Hello”
You can find out about the dte’s properties here:
$dte | get-member | out-gridview
The following is a great way of finding what commands are available to visual studio
$dte.Commands | Out-GridView
And this shows the local environment variables:
gci variable:* | out-gridview
I am wondering if this could be used to add command-line refactoring to visual studio.
