Develop Reference

From TFS I need the code to retrieve the project name from specific collection by passing collection name as parameter using MVC Asp.net

public ActionResult Connect()
{
List<string> Collected = new List<string>(10);
Uri configurationServerUri = new Uri("xxxxxxtfsurl");
TfsConfigurationServer configurationServer =
TfsConfigurationServerFactory.GetConfigurationServer
(configurationServerUri);
ITeamProjectCollectionService tpcService =
configurationServer.GetService<ITeamProjectCollectionService>();
foreach (TeamProjectCollection tpc in
tpcService.GetCollections())
{
Collected.Add(tpc.Name);
}
ViewBag.List = Collected;
return PartialView();
}
I retrieved the collection using controller in MVC but can any one help me to retrieve the projects from specific collection

If you just want to retrieve the team projects from specific collection, then you can use below code sample:
Install Nuget package Microsoft.TeamFoundationServer.ExtendedClient.
using Microsoft.TeamFoundation.VersionControl.Client;
using Microsoft.TeamFoundation.Client;
class Program
{
static void Main(string[] args)
{
string collection = #"http://ictfs2015:8080/tfs/DefaultCollection";
TfsTeamProjectCollection tfs = new TfsTeamProjectCollection(TfsTeamProjectCollection.GetFullyQualifiedUriForName(collection));
tfs.EnsureAuthenticated();
VersionControlServer vcs = tfs.GetService<VersionControlServer>();
TeamProject[] teamProjects = vcs.GetAllTeamProjects(true);
foreach (TeamProject proj in teamProjects)
{
System.Console.WriteLine(string.Format("Team Project: {0}", proj.Name));
}
System.Console.ReadLine();
}
}
If you want to retrieve all the collections and their team projects, then you can try below code sample:
using System;
using System.Collections.ObjectModel;
using Microsoft.TeamFoundation.Client;
using Microsoft.TeamFoundation.Framework.Common;
using Microsoft.TeamFoundation.Framework.Client;
namespace GetProjectList
{
class Program
{
static void Main(String[] args)
{
// Connect to Team Foundation Server
// Server is the name of the server that is running the application tier for Team Foundation.
// Port is the port that Team Foundation uses. The default port is 8080.
// VDir is the virtual path to the Team Foundation application. The default path is tfs.
Uri tfsUri = (args.Length < 1) ?
new Uri("http://ictfs2015:8080/tfs") : new Uri(args[0]);
TfsConfigurationServer configurationServer =
TfsConfigurationServerFactory.GetConfigurationServer(tfsUri);
// Get the catalog of team project collections
ReadOnlyCollection<CatalogNode> collectionNodes = configurationServer.CatalogNode.QueryChildren(
new[] { CatalogResourceTypes.ProjectCollection },
false, CatalogQueryOptions.None);
// List the team project collections
foreach (CatalogNode collectionNode in collectionNodes)
{
// Use the InstanceId property to get the team project collection
Guid collectionId = new Guid(collectionNode.Resource.Properties["InstanceId"]);
TfsTeamProjectCollection teamProjectCollection = configurationServer.GetTeamProjectCollection(collectionId);
// Print the name of the team project collection
Console.WriteLine("Collection: " + teamProjectCollection.Name);
// Get a catalog of team projects for the collection
ReadOnlyCollection<CatalogNode> projectNodes = collectionNode.QueryChildren(
new[] { CatalogResourceTypes.TeamProject },
false, CatalogQueryOptions.None);
// List the team projects in the collection
foreach (CatalogNode projectNode in projectNodes)
{
Console.WriteLine(" Team Project: " + projectNode.Resource.DisplayName);
}
}
// Display the project list on cosole window
Console.ReadLine();
}
}
}

Total number of labels inside a module of TFS repository

I need to find out how many labels are there inside each module of a collection in Team Foundation repository.
I am using TFS 2013.
I know we can get it from Visual Studio. But we need a script which gets us the number of labels as output.
Can anyone help me out in getting a C# or a Powershell code to obtain the same?
TIA

You can use .NET Client Libraries to get this: .NET client libraries for Visual Studio Team Services (and TFS)
Code sample:
using System;
using Microsoft.TeamFoundation.Client;
using Microsoft.TeamFoundation.VersionControl.Client;
namespace GetLabels
{
class Program
{
static void Main(string[] args)
{
string tfscollection = "http://xxx:8080/tfs/defaultcollection";
TfsTeamProjectCollection ttpc = new TfsTeamProjectCollection(new Uri(tfscollection));
VersionControlServer vcs = ttpc.GetService<VersionControlServer>();
string labelname = null;
string labelscope = "$/";
string owner = null;
bool includeitem = false;
int labelnumber;
VersionControlLabel[] labels = vcs.QueryLabels(labelname,labelscope,owner,includeitem);
labelnumber = labels.Length;
Console.WriteLine(labelnumber);
Console.ReadLine();
}
}
}

Creating folder in VSO via VSO API

I have been trying to figure out how is possible to create a query folder via VSO api, but I always the "Method not allowed" message.
I'm using Microsoft.TeamFoundationServer.Client package to connect VSO. This page says that this library is needed for me. I can query data, but it seems something is missing to create data. This library is fit for me because I have a WebApi whihch manages the communication to VSO API.
Here is my code:
public QueryHierarchyItem CreateFolderAsync(string folderName)
{
QueryHierarchyItem newFolder = new QueryHierarchyItem()
{
Name = folderName,
IsFolder = true,
//Path = "Queries/Shared Queries/" + folderName,
IsPublic = true
};
QueryHierarchyItem item = witClient.CreateQueryAsync(newFolder, _projectName, null).Result;
return item;
}
I have tried to play with the Path property but it did not help.
I have checked the user rights. My user is member of "Project Administrators", and
rights are also set up to manage query folders (Click the chevron next to the "Shared Queries" folder -> select "Security") as group and as single user. It did not help.
I use a free account. The strange is that I have logged in with the same user from Visual Studio and I can manage the folders. Is this functionality available for free accounts?

You can refer to this blog from MSDN for details: http://blogs.msdn.com/b/team_foundation/archive/2010/06/16/work-item-tracking-queries-object-model-in-2010.aspx
Quote the code here:
using System;
using Microsoft.TeamFoundation.Client;
using Microsoft.TeamFoundation.WorkItemTracking.Client;
namespace QueryAPI
{
class Program
{
private static Project myproject = null;
public static QueryFolder GetMyQueriesFolder()
{
foreach (QueryFolder folder in myproject.QueryHierarchy)
{
if (folder.IsPersonal == true)
return folder;
}
throw new Exception("Cannot find the My Queries folder");
}
public static QueryFolder AddNewFolder(string folderName)
{
QueryFolder folder = new QueryFolder(folderName, GetMyQueriesFolder());
myproject.QueryHierarchy.Save();
return folder;
}
static void Main(string[] args)
{
TfsTeamProjectCollection coll = TfsTeamProjectCollectionFactory.GetTeamProjectCollection(new Uri("Your TFS Server URI"));
WorkItemStore store = new WorkItemStore(coll);
myproject = store.Projects["Your project name"];
QueryFolder myNewfolder = AddNewFolder("Your folder name");
}
}
}

test build agents of a build controller using tfs api

I want to automate testing of newly created build agents in TFS.
Now, I have written code to queue builds of particular build definition on TFS.
Problem I am facing is to queue build definition on agents of given controller.
Previously there was one method which I've commented in my code
for doing this, i.e. IbuildRequest.buildagent, but now it has been deprecated in newer tfs api.
Edit:
I have already tested IbuildRequest.BuildController property which tends to randomly pick agent, which is currently free.
What I want to know is can I force build definition to use one build Agent using tfs api.
using System;
using System.Linq;
using System.Security.Principal;
using System.Collections.Generic;
using Microsoft.TeamFoundation.Client;
using Microsoft.TeamFoundation.Build.Client;
using Microsoft.TeamFoundation.WorkItemTracking.Client;
namespace BuildAgentsTestApp
{
class Program
{
static void Main(string[] args)
{
Uri collectionURI = new Uri("https://tfs-uri");
var tfsCreds = new TfsClientCredentials(new WindowsCredential(), true);
TfsTeamProjectCollection tfs = new TfsTeamProjectCollection(collectionURI,tfsCreds);
WindowsIdentity user = WindowsIdentity.GetCurrent();
tfs.EnsureAuthenticated();
if (tfs.HasAuthenticated)
{
WorkItemStore workItemStore = tfs.GetService<WorkItemStore>();
Project teamProject = workItemStore.Projects["myProjectName"];
IBuildServer buildServer = (IBuildServer)tfs.GetService(typeof(IBuildServer));
IBuildDefinition buildDef = buildServer.GetBuildDefinition(teamProject.Name, "myBuildDefinitionName");
var controller = GetRequestedController(buildServer, "myControllerName");
var AgentsList = GetAgentCollection(controller);
//Queue each build definition
IBuildRequest buildRequest = buildDef.CreateBuildRequest();
buildRequest.GetOption = GetOption.Custom;
//buildRequest.BuildAgent = AgentsList.First();
buildServer.QueueBuild(buildRequest);
}
Console.WriteLine("Build Queued!");
Console.ReadKey();
}
static IBuildController GetRequestedController(IBuildServer reqBuildServer, string reqControllerName)
{
var requiredController = reqBuildServer.QueryBuildControllers()
.Where(ctrl =>
ctrl.Name == reqControllerName
).FirstOrDefault();
return requiredController;
}
static List<IBuildAgent> GetAgentCollection(IBuildController controller)
{
var ListOfAgents = from agent in controller.Agents
select agent;
return ListOfAgents.ToList();
}
}
}

Roslyn Run Code in AppDomain

I added Roslyn my project.
Roslyn can run script from string like
using Roslyn.Scripting.CSharp;
namespace RoslynScriptingDemo
{
class Program
{
static void Main(string[] args)
{
var engine = new ScriptEngine();
engine.Execute(#"System.Console.WriteLine(""Hello Roslyn"");");
}
}
}
but I wanna access the controls,properties,variables in the form.
For Example There is a textbox in form.
var engine = new ScriptEngine();
engine.Execute(#" textbox1.Text="SK"; ");
Can I access controls in Roslyn?

You could set up a host object for your script session that has a public property for the controls you want to access.
