TFS API TestManagementService always returns null

I'm trying to get test plans by using 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 idea, why?

Perhaps you're linking against different versions of reference assemblies, 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 of GetService<ITestManagementService>() always returning null, even when GetService<VersionControlServer>() would return good (non-null) value.

The solution posted in MSDN - VersionControlServer always returns null worked for me: I had references to some v11.0 (VS2012) and v12.0 (VS2013) assemblies. Changing all references to v11.0 fixed it for me.

Try to make sure you that you are authenticated to the Team Project Collection before calling the Get Service command. This code snippet works correctly for me:

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

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