TF30063:您无权...编程访问不起作用 [英] TF30063: You are not authorized ... programmatic access not working

问题描述

此 answer 中提供的以下代码在一段时间内效果很好，但现在抛出 Microsoft.TeamFoundation.TeamFoundationServerUnauthorizedException:'TF30063:您无权再次访问https://{mysite} .visualstudio.com/..

The code below provided in this answer did work well for a while but now its throwing Microsoft.TeamFoundation.TeamFoundationServerUnauthorizedException: 'TF30063: You are not authorized to access https://{mysite}.visualstudio.com/.' again.

var credentials = new VssClientCredentials();
credentials.PromptType = CredentialPromptType.PromptIfNeeded;

var teamProjects = new TfsTeamProjectCollection(tfsCollectionUri, credentials);
teamProjects.EnsureAuthenticated();         // exception thrown

Q 如何解决此问题?

更新足够奇怪

1. 在执行teamProjects.EnsureAuthenticated();之前，调试器为credentials.PromptType读取PromptIfNeeded.
2. 引发异常并且调试器停止执行之后，它会读取DoNotPrompt作为credentials.PromptType.

1. before executing teamProjects.EnsureAuthenticated(); the debugger reads PromptIfNeeded for credentials.PromptType.
2. after the exception has been thrown and the debugger has stopped the execution, it reads DoNotPrompt for credentials.PromptType.

观察 上面的代码在控制台应用程序中可以很好地运行，但是在Windows窗体应用程序中则无法工作(即，它引发异常).

Observation The above code works perfectly well in a console application but fails to work in a windows forms application (i.e. it throws an exception).

第1季度如何在Windows窗体应用程序中使以上代码工作?

Q1 How can I make the above code work in a windows forms application?

推荐答案

如果您在Task(即一个单独的线程)中执行上述代码，那么它就可以正常工作.如果凭据在注册表中的位置不存在或过时(请参阅此 answer )，则会打开一个窗口，您可以进行身份​​验证你自己.

If you execute the code above within a Task (i.e. a separate thread) it just works. If the credentials are not present or stale at the location in the registry (see this answer) a window opens and you can authenticate yourself.

任何人都可以解释为什么这样做有效吗?

Can anyone explain why this works?
