Question: how do I connect ? Thanks.

推荐答案

根据您的描述，我猜想此方法永远不会返回的原因是您在带有等待关键字的sync Controller方法中将async方法称为了.

According to your description, I guess the reason why this methods never returns is you called the async method in the sync Controller method with wait keywords.

如果按如下所示调用getResultAsync，它将永远不会返回结果:

If you call the getResultAsync as below, it will never return the result :

    public ActionResult Index()
    {
       getResultAsync().Wait();
        return View();
    }

    public static async Task getResultAsync()
    {
        string subscription = "subid";

        string tenantid = "tenantid ";
        string clientId = "clientId ";
        string key = "key";

        var serviceCreds = await ApplicationTokenProvider.LoginSilentAsync(tenantDomain, clientId, key);

        BillingManagementClient b1 = new BillingManagementClient(serviceCreds) { SubscriptionId = subscription };


        var result = b1.Operations.List();

    }

我建议您可以如下更改索引方法，它将很好地工作:

I suggest you could change the index method as below, it will work well:

   public async Task<ActionResult> Index()
        {
            await getResultAsync();
            return View();
        }

结果:
