c# - 发送聊天消息

Question

我有这个代码:

var msg = new ChatMessage();
msg.Body = "Test";
msg.Recipients.Add("number");

var cms = await ChatMessageManager.RequestStoreAsync();
await cms.SendMessageAsync(msg);

我对上面代码的 await 部分有疑问。我得到异常:

Access is denied.

在 appxmanifest 的功能中，我选择了:

Chat Message Access

(我试过全选，但没用)。我找不到任何必须满足的 sample 和要求。

感谢您的帮助。

如果你看一下at MSDN你会看到:

This API is not available to all Windows/Windows Phone apps. Unless your developer account is specially provisioned by Microsoft, calls to these APIs will fail at runtime.
