Get A team project and create a work item without using get the work items store

I am Using the code below to create a new work item under a certain project programmatically using c# as below:

        TfsTeamProjectCollection tfs = new TfsTeamProjectCollection(
        TfsTeamProjectCollection.GetFullyQualifiedUriForName("http://tfssssrv:8080/tfs"));


        //Get data store that contains all workitems on a particular server
        WorkItemStore store = tfs.GetService<WorkItemStore>();

        //Get particular Team Project
        Project project = store.Projects["MAKAROV"];

I am being able to connect but the tfs.GetService() to get the stores is taking a lot of time to get the Data (around 148 Team Project and 70000 work items). I need to retrieve the Team Project without going through the Store and create the work item under it. i am sure there is another way but can't seem to find it on the internet.

Solution

It is not possible to manipulate work items in TFS 2005 through 2013 without getting the WorkItemStore object. In 2012 & 2013 the speed has been greatly increased but if you have lots of Team Projects you can still have performance issues.

The recommendation is to cache the object.
