TFS以编程方式注销

Question

如何从代码中退出TFS 2012（云）？

尝试了一些事情，但身份提供商总是加载相同的凭据。

更新 我试过的一些代码

ClientCredentials tfsClientCredentials = new TfsClientCredentials(false);
TfsConfigurationServer serverConfig = new TfsConfigurationServer(uri, tfsClientCredentials);
serverConfig.EnsureAuthenticated();

和第二个片段

TfsConfigurationServer serverConfig = new TfsConfigurationServer(uri, new UICredentialsProvider());
serverConfig.EnsureAuthenticated();

和第三个

ICredentialsProvider provider = new UICredentialsProvider();
WindowsCredential wcred = new WindowsCredential(cred, provider);
TfsClientCredentials tfsClientCredentials = new TfsClientCredentials(wcred);
TfsConfigurationServer serverConfig = new TfsConfigurationServer(uri, tfsClientCredentials);
serverConfig.EnsureAuthenticated();
