ask for version control server (client) from VssConnection - tfs

Question

Dears
Please help me to work with VssConnection from Microsoft.VisualStudio.Services.Client.15.134.0-preview package
I need to get pending changes for workspace, query it for conflict and commit
This is how i do it with TfsTeamProjectCollection and
var vssCred = new VssClientCredentials();
using (TfsTeamProjectCollection collection = new TfsTeamProjectCollection(uri, vssCred))
{
collection.Authenticate();
var scs = collection.GetService<VersionControlServer>();
var scsProject = scs.GetTeamProject(teamProjectName);
var workspace = scsProject.VersionControlServer.GetWorkspace(localPath);
var pending = scs.QueryPendingSets(new string[] { "$/" }, RecursionType.Full, workspace.Name, loginName);
if (pending.Any())
{
var pendingChanges = new[] { pending.First().PendingChanges.First() };
var validation = workspace.EvaluateCheckin2(CheckinEvaluationOptions.Conflicts, pendingChanges, "", null, null);
var conflicts = validation.Conflicts;
if (conflicts != null && conflicts.Any())
{
var message = string.Join("\r\n", conflicts.Select(_ => string.Format("{0} {1}", _.Message, _.ServerItem)));
throw new ArgumentException(string.Format("conflict was found\r\n{0}", message));
}
var res = workspace.CheckIn(pendingChanges, "test checkin");
TestContext.WriteLine("checked in {0}", res);
}
}
However there are vsts integration samples that uses VssConnection object
How can I get the same VersionControlServer from VssConnection instance?
I've tried to find Microsoft.TeamFoundation.VersionControl.Client.WebAPi (like Microsoft.TeamFoundation.WorkItemTracking.WebApi) but failed.
var vssCred = new VssClientCredentials();
using (VssConnection connection = new VssConnection(uri, vssCred))
{
var prj = connection.GetClient<ProjectHttpClient>();
var p = prj.GetProject(teamProjectName).Result;
//i'd like to get prj.VersionControl here
//or something like var scs = connection.GetService<VersionControlServer>();
}
Is it possible to get versionControlServer from VssConnection? Should I continue to use TfsTeamProjectCollection to do this task?

Answer 1

You could use TfsTeamProjectCollection as before, as there is no workspace method in VssConnection:
TfvcHttpClient tfvcClient = connection.GetClient<TfvcHttpClient>();
List <TfvcItem> tfvcItems = tfvcClient.GetItemsAsync("$/", VersionControlRecursionType.OneLevel).Result;
