How to wait till the TFS Build Queued is completed in Powershell

Question

One of our requirements is to wait till the TFS build which is queued is completed and then we need to perform next task, I have written the below code to achieve this but this isn't giving me the desired results.

function Wait-QueuedBuild ()
{
     $serverName="http://tfs001:8080/tfs/Collection"

     $tfs = [Microsoft.TeamFoundation.Client.TeamFoundationServerFactory]::GetServer($serverName)

     $buildserver = $tfs.GetService([Microsoft.TeamFoundation.Build.Client.IBuildServer])

     $build = $buildServer.QueueBuild($buildServer.GetBuildDefinition("CollectionUtility\BUILD_FULL",$_.Name))

     do
     {   
         sleep 1        
     }
     while (!(build.Status -eq 'InProgress'))
}

You need to keep querying the build status in the loop just as Andrey mentioned. The code should like:

do {
    sleep 1;
    $queryoption = [Microsoft.TeamFoundation.Build.Client.QueryOptions]::All;
    $build = $buildserver.GetQueuedBuild($build.Id,$queryoption);
}
while ($build.Status -eq 'InProgress')
