Using the nupack Package Manager Console to set working folder to solution folder - powershell

Question

In Visual Studio, nupack adds a power-shell window called the Package Manager Console. I am thinking that this would be a good place to run source control commands (I'm using Mercurial). However, the default working directory is my users folder, so I need to navigate to my code folder every time I load a new project.
I am wondering if there is a one-line command to set the working directory to the solution folder. e.g. does something like this exist?
cd $SolutionFolder
From the results of get-variable it doens't look like there is anything immediately available, but I've never used powershell before, so maybe there is a way of getting the solution folder?

Answer 1

Thanks to Doug for pointing me in the right direction. I've written up full instructions on my blog here:

The basic answer is that the following command will do it:
Split-Path -parent $dte.Solution.FileName | cd
To make it more readily available, you need to create a function in your "user profile" script file, the location of which is found in the $profile variable. You will need to create the file if it doesn't exist. Then add a function:
Function solutionFolder()
{
Split-Path -parent $dte.Solution.FileName | cd
}
Now, after loading a solution in VS2010, you can simply type:
solutionFolder
and the working folder will be changed.

Answer 2

Try
$dte.Solution.FileName

Answer 3

I'm not sure when it changed, but the Package Manager Console automatically shifts the working directory to the current solution folder when you open an application now.
