Get latest from Visual Studio Team Services using Command Line passing /login credentials with TF.exe

Question

Has anyone had success getting latest source code from the Visual Studio Team Services (formerly Visual Studio Online, Team Foundation Service) Version Control Server using

Answer 1

Here is a snippet using .NET TFS libraries & Powershell integration that worked for us - tf.exe does not play well with VSO authorization. Curious if anyone else has success using this route. We are using ADFS, so the powershell process is run as the user we want to authenticate with.

TF Get Latest Workspace.ps1

$path = "C:\Program Files (x86)\Microsoft Visual Studio 12.0\Common7\IDE\ReferenceAssemblies\v2.0" 
Add-Type -Path "$path\Microsoft.TeamFoundation.Client.dll"
Add-Type -Path "$path\Microsoft.TeamFoundation.VersionControl.Client.dll"
Add-Type -Path "$path\Microsoft.TeamFoundation.VersionControl.Common.dll"
 
$collection = "https://mycorp.visualstudio.com/defaultcollection"
$tpc = [Microsoft.TeamFoundation.Client.TfsTeamProjectCollectionFactory]::GetTeamProjectCollection($collection)
$vc = $tpc.GetService([Microsoft.TeamFoundation.VersionControl.Client.VersionControlServer])

# retrieve workspace by path 
$projectPath = "$/MyApp/MyBranch"
$workspacePath = "C:\Projects\MyApp\MyBranch"
$workspace = $vc.GetWorkspace($workspacePath)


# get full download every time (tf get /force /recursive)
function DownloadAllFiles([Microsoft.TeamFoundation.VersionControl.Client.Workspace] $workspace, [string] $projectPath) {     
    $recursionType = [Microsoft.TeamFoundation.VersionControl.Client.RecursionType]::Full
    $versionSpec = [Microsoft.TeamFoundation.VersionControl.Client.LatestVersionSpec]::Instance
    $itemSpec = new-object Microsoft.TeamFoundation.VersionControl.Client.ItemSpec($projectPath,$recursionType)
    $getRequest = New-Object Microsoft.TeamFoundation.VersionControl.Client.GetRequest($projectPath,$recursionType,$versionSpec)
    $getOptions = [Microsoft.TeamFoundation.VersionControl.Client.GetOptions]::GetAll -bor [Microsoft.TeamFoundation.VersionControl.Client.GetOptions]::Overwrite 
    $workpaceStatus = $workspace.Get($getRequest, $getOptions)
    write-output $workpaceStatus 
}

# get delta download - changes only (retrieves all mapped items)
function DownloadWorkspaceUpdates([Microsoft.TeamFoundation.VersionControl.Client.Workspace] $workspace) {
    $workpaceStatus = $workspace.Get()
    write-output $workpaceStatus 
}

# get delta download - changes only (retrieves specific mapped items)
function DownloadWorkspaceUpdates([Microsoft.TeamFoundation.VersionControl.Client.Workspace] $workspace, [string] $projectPath) {
    $recursionType = [Microsoft.TeamFoundation.VersionControl.Client.RecursionType]::Full
    $versionSpec = [Microsoft.TeamFoundation.VersionControl.Client.LatestVersionSpec]::Instance
    $itemSpec = new-object Microsoft.TeamFoundation.VersionControl.Client.ItemSpec($projectPath,$recursionType)
    $getRequest = New-Object Microsoft.TeamFoundation.VersionControl.Client.GetRequest($projectPath,$recursionType,$versionSpec)
    $getOptions = [Microsoft.TeamFoundation.VersionControl.Client.GetOptions]::Overwrite 
    $workpaceStatus = $workspace.Get($getRequest, $getOptions)
    write-output $workpaceStatus 
}

# force latest download (slower)
DownloadAllFiles -workspace $workspace -projectPath $projectPath

# download deltas (fast), all mappings
DownloadWorkspaceUpdates -workspace $workspace

# download deltas (fast), specific mapping
DownloadWorkspaceUpdates -workspace $workspace -projectPath $projectPath

This could easily be extended to support TfsClientCredentials (i.e. Alternate Access credentials). I prefer the powershell approach as it doesn't require compilation or an extra EXE to copy around.
