找不到方法:“System.Xml.XmlElement Microsoft.TeamFoundation.WorkItemTracking.Internals.WiqlAdapter.GetQueryXml(System.String, System.Collections.IDictionary, Boolean, Boolean)”。

有朋友知道是什么原因吗？
代码：
WorkItemStore store = new WorkItemStore("http://localhost:8080/tfs/TESTCollection/");
string wiql = "select * from WorkItems where [工作项类型] = '问题' ";
WorkItemCollection queryResults = store.Query(wiql);  //这里出错，在别的电脑正常运行，我自己的却不行
错误信息：
找不到方法:“System.Xml.XmlElement Microsoft.TeamFoundation.WorkItemTracking.Internals.WiqlAdapter.GetQueryXml(System.String, System.Collections.IDictionary, Boolean, Boolean)”。
