C# Windows 10 Iot/UWP上的Azure存储库客户端？

Windows 10 Iot Core/UWP（RPi）上似乎不支持Azure存储客户端。然而，我使用它来处理blob，它也可以很好地处理表。现在，在更新到最新的stable（并且-pre，尝试了两者）之后，对表的访问挂起

await table.ExecuteQuerySegmentedAsync(query, new TableContinuationToken());

我徒劳地寻找了一种方法来实现这个同步，这至少可以帮助我调试它。我还想知道其他人目前的成功，以及在物联网核心（RPi）上使用Azure存储客户端的“独家新闻”

更新： 扩展了RequestOptions，如下所示，我的简单调用也显示在下面。我仔细检查了连接字符串、表访问（来自其他工具）和帐户。他们都在其他地方工作得很好。我还将VStudio2015远程调试中的异常粘贴到IoT Core RaspberryPi最新版本

        // Setup the table container
        // connectString looks fine, works fine elsewhere: http for debug instead of https 
        var connectionString = @"DefaultEndpointsProtocol=http;AccountName=myaccount;AccountKey=EUybijab+WHATEVERDzYubKGADwjf/6k5IuoRVgPMMqMez0gb07/dfAv9Qj1/v7NkstGAygWNab07q6FhNBQ==";

        var cloudStorageAccount = CloudStorageAccount.Parse(connectionString);
        CloudTableClient cloudTableClient = cloudStorageAccount.CreateCloudTableClient();
        cloudTable = cloudTableClient.GetTableReference(appSettings.AzureStorageOeConfigTableName);
        //never returns var x = await cloudTable.CreateIfNotExistsAsync();

        // Simplest query to existing small table
        var pkey = "b8-27-eb-86-5d-4d";
        var rkey = "0000000013505717";
        var tstOp = TableOperation.Retrieve(pkey, rkey);
        var requestOptions = new TableRequestOptions
        {
            PayloadFormat = TablePayloadFormat.JsonFullMetadata,
            LocationMode = LocationMode.PrimaryThenSecondary,
            RetryPolicy = new ExponentialRetry(),
            ServerTimeout = TimeSpan.FromMinutes(2)
        };
        // Throws exceptions shown below.
        var tst1 = await table.ExecuteAsync(tstOp, requestOptions, null);

例外：对我的测试代码有什么想法或修改吗

是的，不幸的是，UWP应用程序还不受存储的支持，因为UWP平台中存在一个导致Auth出现问题的bug。我们正在等待UWP团队的修复。谢谢

首先，您可以始终使用RESTAPI—客户端库只是它的包装器。第二，为什么您认为使某些东西“同步”会使调试变得更容易而不是更难<代码>等待没有任何魔力，它等待一个已经异步的操作。HTTP调用甚至在桌面上也是异步的——这实际上是一个操作系统的技巧，使它们看起来是同步的。您是否尝试过将代码包装在try/catch块中并记录异常？你等电话回音等了多久？您使用的超时值是多少？谢谢。是的，我已经在IoT core上为服务总线使用了RESTAPI，使用客户端库更简单。是的，试试看。在IoT core ARM平台上，该调用只是挂起、永不返回，也从不引发异常。我已经打开了所有可以看到的东西，包括CLR异常。只是挂了。无法解释，因为它正在工作…请求可能花费的时间太长，或者导致重试次数太多。您是否尝试通过设置了

MaximumExecutionTime

或

ServerTimeout

来传递问题？使用测试代码和返回的异常（VisualStudio 2015远程调试器）更新了问题。任何想法都值得赞赏。由于我使用此存储库来管理同一IoT核心应用程序中的BLOB，我仍然希望在我的表中使用它（而不是REST）。似乎是同一个问题：请通过此频道告知我们。谢谢
