How can I retrieve a list of workitems from TFS in C#?

Question

I\'m trying to write a project reporting tool in WPF / C#. I want to access all the project names on our TFS (Team Foundation Server), and then display statistics for each work

You need to use WIQL queries to get actual work items you are interested in, e.g. to get all work items for a particular project:

using Microsoft.TeamFoundation.WorkItemTracking.Client;

Query query = new Query(
     workItemStore, 
     "select * from issue where System.TeamProject = @project",
     new Dictionary<string, string>() { { "project", project.Name } }
);

var workItemCollection = query.RunQuery();
foreach(Microsoft.TeamFoundation.WorkItemTracking.Client.WorkItem workItem in workItemCollection) 
{
   /*Get work item properties you are interested in*/
   foreach(Microsoft.TeamFoundation.WorkItemTracking.Client.Field field in workItem.Fields)
   {
      /*Get field value*/
      info += String.Format("Field name: {0} Value: {1}\n", field.Name, field.Value);
   }
}
