我希望能够编写类似的代码

using (await LockAsync(x.Id))
{
    // here goes code that is unsafe with respect to x.Id
    // because it can be executed in multiple threads on
    // the same instance or on multiple instances (e.g.
    // multiple Azure Functions
}

我知道有一些开箱即用的方法可以在不使用密钥的情况下锁定整个执行上下文（例如[ActivityTrigger]在函数中），并且我知道我可以使用 blob 租约滚动自己的带钥匙的锁，但是有没有一种开箱即用的方法钥匙锁？

我有一个函数应用程序定义如下

[StorageAccount("DefaultEndpointsProtocol=...;AccountName=…;AccountKey=...")]
public static class Function1
{
    [FunctionName("Function1")]
    [return: Queue("lets-test-this-out")]
    public static async Task<string> Run([QueueTrigger("lets-test-this-in")] Guid  guid, TraceWriter log)
    {
        await Task.Delay(1000);
        log.Info($"C# Queue trigger function processed: {guid}");
        return Guid.NewGuid().ToString();
    }
}

其中lets-test-this-in和lets-test-this-out是带有连接字符串的存储帐户下的现有存储队列的名称"DefaultEndpointsProtocol=...;AccountName=…;AccountKey=..."（直接从访问键 - 连接字符串复制门户中的）。我发布时生成的 function.json 就像

{
  "generatedBy": "Microsoft.NET.Sdk.Functions.Generator-1.0.6",
  "configurationSource": "attributes",
  "bindings": [
    {
      "type": "queueTrigger",
      "queueName": "lets-test-this-in",
      "connection": "DefaultEndpointsProtocol=...;AccountName=...;AccountKey=...;",
      "name": "guid"
    }
  ],
  "disabled": false,
  "scriptFile": "../bin/FunctionAppTest.dll",
  "entryPoint": "FunctionAppTest.Function1.Run"
}
