无法初始化TFS商店

Question

我想在Visual Studio Team Services（以前的Visual Studio Online）中创建一个任务/工作项目。我的代码失败，因为“tfsStore”返回空值导致异常被抛出。

NetworkCredential myNetCredentials = new NetworkCredential("*****", "******"); 
ICredentials myCredentials = (ICredentials)myNetCredentials; 
Uri tfsUri = new Uri("https://*****.visualstudio.com/DefaultCollection/"); 
var tfsServer = new TfsTeamProjectCollection(tfsUri, myCredentials); 
tfsServer.EnsureAuthenticated(); 
TfsTeamProjectCollection tpc = new TfsTeamProjectCollection(tfsUri); 
WorkItemStore tfsStore = tfsServer.GetService<WorkItemStore>(); 
if (tfsStore == null) 
{ 
    throw new Exception("Cannot initialize TFS Store"); 
} 
Project teamProject = tfsStore.Projects["******"]; 

我将不胜感激关于如何解决错误的任何有用的提示。 谢谢！

我测试过下面的代码片段在我的身边，它可以成功地创建一个任务工作项，你可能有一个尝试：

NetworkCredential myNetCredentials = new NetworkCredential("******", "******"); 
TfsTeamProjectCollection tfsUri = new TfsTeamProjectCollection(new Uri("https://*****.visualstudio.com/DefaultCollection"), myNetCredentials); 
WorkItemStore tfsStore = tfsUri.GetService<WorkItemStore>(); 
     if (tfsStore == null) 
      { 
       throw new Exception("Cannot initialize TFS Store"); 
      } 

     Project teamProject = tfsStore.Projects["*****"]; 
     WorkItemType workItemType = teamProject.WorkItemTypes["Task"]; 
     WorkItem Task = new WorkItem(workItemType) 
      { 
       Title = "APITask", 
      }; 
      Task.Save(); 

包括.NET API，您还可以使用REST API，这很简单：

PATCH https://{instance}/DefaultCollection/{project}/_apis/wit/workitems/${workItemTypeName}?api-version={version}
