How Can I "Update-Package" to a Previous Version in the Package Manager Console?

Question

I have a version of a package installed in my project but during testing I have found a problem with it. I tried the obvious thing Update-Package -Id Foo.Bar -Version 1.0.0 -Force but the Update-Package cmdlet doesn't have a -Force parameter, and it doesn't allow updates to an earlier version. How do I downgrade my package dependencies (without taking advantage of source control!)

---

NOTE: This question is now irrelevant because Update-Package MyPackage -Version [an earlier version] works out of the box in recent versions of NuGet Package Manager. You don't even need a -Force switch.

I think I already have a solution to this so I place it here for (constructive) criticism.

function Reinstall-Package {      param(         [Parameter(Mandatory = $true)]         [string]         $Id,          [Parameter(Mandatory = $true)]         [string]         $Version,          [Parameter(ValueFromPipeline = $true, ValueFromPipelineByPropertyName = $true)]         [string]         $ProjectName,          [switch]         $Force     )      if (-not $ProjectName) {         $ProjectName = (get-project).ProjectName     }      Uninstall-Package -ProjectName $ProjectName -Id $Id -Force:$Force     Install-Package -ProjectName $ProjectName -Id $Id -Version $Version  } 

This allows us to use a call such as the following to update all references to a package within the current solution.

 Get-Project -All |      ?{ $_ | Get-Package | ?{ $_.Id -eq 'Foo.Bar' } } |          %{ $_ | Reinstall-Package -Id Foo.Bar -version 1.0.0 -Force } 

The -Force switch allows the package to be reinstalled even if it has dependent packages within the project.

With NuGet 2.8 client or higher, Install-Package can be used to downgrade the existing packages in your project, if necessary. For example, if you had installed a pre-release version of a package to try out new features but would like to go back to a previous stable version you can do so using Install-Package (or Update-Package).
