TFS 2010, Build Definitions, and Powershell

I needed to get a list of build definitions from a TFS 2010 instance as we are planning to migrate to a new server and will not be moving the collection, but only the builds and source files inside the collection. The following Powershell scripts will list out the build definitions for a server:

clear-host

[void][System.Reflection.Assembly]::LoadWithPartialName("Microsoft.TeamFoundation.Client")
[void][System.Reflection.Assembly]::LoadWithPartialName("Microsoft.TeamFoundation.Build.Client")
[void][System.Reflection.Assembly]::LoadWithPartialName("Microsoft.TeamFoundation.WorkItemTracking.Client")


$tfsCollectionUrl = "http://{server}:8080/tfs/{collection}"
$server = new-object Microsoft.TeamFoundation.Client.TfsTeamProjectCollection(New-Object Uri($tfsCollectionUrl))
$buildServer = $server.GetService([Microsoft.TeamFoundation.Build.Client.IBuildServer])
$workStore = $server.GetService([Microsoft.TeamFoundation.WorkItemTracking.Client.WorkItemStore])

$workStore.Projects | ForEach-Object {
Write-Host ("Project: "+$_.Name)
$buildServer.QueryBuildDefinitions($_.Name) | select-object {$_.Name, $_.ContinuousIntegrationType} | format-table
}
