.net core 如何使用.NETCore访问Google云数据存储模拟器？

我在.Net Core v3.1中有一个简单的控制台程序：

static void Main(string[] args)
{
    var db = new DatastoreDbBuilder 
    {
        ProjectId = "simple-proj",
        EmulatorDetection = EmulatorDetection.EmulatorOnly
    }.Build();

    var keyFactory = db.CreateKeyFactory("Simple");
    using (var transaction = db.BeginTransaction())
    {
        transaction.Insert(new Entity { Key = keyFactory.CreateIncompleteKey(), ["Message"] = "Hello" });
        transaction.Commit();
    }
}

我正在使用Google.Cloud.Datastore.V1 v3.0.0库从我的C#代码访问数据存储。我启动了仿真器，并使用$（gcloud beta-emulators datastore env init）设置环境变量，如文档所示。我从emulator端点收到OK消息(http://localhost:8081)当我通过浏览器访问它时。一切似乎都井然有序

这是我在.Net控制台上获得的堆栈转储：

我是否在代码或模拟器的设置中遗漏了一些明显的内容？

您是否仍在对此进行阻止？如果是这样，我来看看。@DazWilkin我从来没有让它按照医生建议的方式工作过。我最终使用了这个问题中描述的方法。。。文档混乱，链接中断。真不幸。可能有趣的是，emulator报告“检测到非HTTP/2连接”（即非gRPC）。你也收到了吗？.NET客户端建议（！）它正在使用gRPC（

gRPC.Core.RpcException

）。你在Google@dazwilkin上提交了一份bug报告吗？谢谢你提交。我曾考虑过向github repo提交一个API问题，但想看看我是否误解了什么。很高兴我不是唯一一个觉得缺少文档的人。你还在阻止这个吗？如果是这样，我来看看。@DazWilkin我从来没有让它按照医生建议的方式工作过。我最终使用了这个问题中描述的方法。。。文档混乱，链接中断。真不幸。可能有趣的是，emulator报告“检测到非HTTP/2连接”（即非gRPC）。你也收到了吗？.NET客户端建议（！）它正在使用gRPC（
