C# – TFS API – How to fetch work item(s) from specific Team Project

ctfstfs-sdk

I am trying to query a single team project in the main TfsTeamProjectCollection which contains 194 Team Projects in total. I know exactly how to get a WorkItem by Id from a WorkItemStore. The thing is, that by doing this, the API searches in ALL of the projects in the collection and the query takes about a minute. This is way too slow, there must be a way to query work items directly from a single team project ? Here is the code I have:

    private Uri collectionUri;
    private TfsTeamProjectCollection projectCollection;
    private WorkItemStore workItemStore;

    public Project GetTeamProject()
    {
        projectCollection = TfsTeamProjectCollectionFactory.GetTeamProjectCollection(collectionUri);

        workItemStore = projectCollection.GetService<WorkItemStore>();
        Project teamProject = workItemStore.Projects[TFS_PROJECT_KEY];
        return teamProject;
    }

Now that I have the Team Project I'm interested in, how can I query for work items by ID or just get all work items in this project ?

Best Answer

You could try something like this for getting all WIs within teamProject:

WorkItemCollection workItemCollection = workItemStore.Query(
     " SELECT [System.Id], [System.WorkItemType],"+    
     " [System.State], [System.AssignedTo], [System.Title] "+ 
     " FROM WorkItems " +
     " WHERE [System.TeamProject] = '" + teamProject.Name +
    "' ORDER BY [System.WorkItemType], [System.Id]");

And this to get a specific WorkItem ID:

WorkItem workItem = workItemStore.GetWorkItem(555);
