TFS API TestManagementService always returns null

I am trying to get test plans using the TFS API.

TfsTeamProjectCollection tfs = TfsTeamProjectCollectionFactory.GetTeamProjectCollection(new Uri("http://xxxxxxx:8080/tfs/DefaultCollection"));

var service = (ITestManagementService)tfs.GetService(typeof(ITestManagementService));

The variable "service" always returns null.

Do you have any ideas why?

Perhaps you are linking to different versions of referenced assemblies by mixing different versions of Visual Studio assemblies? Example:

  • Microsoft.TeamFoundation.Client v11.0 (VS 2012)
  • Microsoft.TeamFoundation.TestManagement.Client v12.0 (VS 2013)

I had the same problem GetService<ITestManagementService>()always returning null even when it returned a GetService<VersionControlServer>()good (non-zero) value.

MSDN - VersionControlServer null : v11.0 (VS2012) v12. 0 (VS2013). v11.0 .

, Get Service. :

TfsTeamProjectCollection tpc = TfsTeamProjectCollectionFactory.GetTeamProjectCollection(new Uri("https://tfs.companyname.com/tfs/DefaultCollection"));
tpc.EnsureAuthenticated();

ITestManagementService service = tpc.GetService<ITestManagementService>();
