通过Asp.Net WebForms访问VS-Team Services OAuth

我需要通过OAuth2连接WebService中的VS-Team-Services。
我在官方网站上发现了sample solution，但我无法修改它在我们的Web服务代码中使用它。
因为它在请求访问令牌时请求许可Accept or Deny。
我需要它自动授予访问没有权限页的令牌。通过Asp.Net WebForms访问VS-Team Services OAuth

这是我以前的工作代码没有OAuth。我需要根据OAuth修改此代码。

     configurationServer.EnsureAuthenticated(); 

     ReadOnlyCollection<CatalogNode> collectionNodes = configurationServer.CatalogNode.QueryChildren(new[] { CatalogResourceTypes.ProjectCollection }, false, CatalogQueryOptions.None);
