SuspensionManager.RestoreAsync中的异常 [英] Exception in SuspensionManager.RestoreAsync

问题描述

有时如果我使用CTRL + SHIFT + F5退出我的应用程序并重新启动它，我会在这一行得到一个例外：

Sometimes if I use CTRL+SHIFT+F5 to exit my application and restart it, I get an exception on this line:

if (args.PreviousExecutionState == ApplicationExecutionState.Terminated)
{
    // Do an asynchronous restore
    await SuspensionManager.RestoreAsync();
}

 

用户代码未处理System.IO.FileNotFoundException

  HResult = -2147024894

 消息=系统找不到指定的文件。 （HRESULT的例外情况：0x80070002）

大概这是因为我的应用程序已经停止并且没有保存会话状态但是Windows已经决定它已被终止。

Presumably this is because my application was stopped and did not save session state, but Windows has decided that it has been terminated.

所以问题是，是否需要在暂停管理器中进行一些更改来处理这种情况，或者它是否是一个错误Windows错误地报告它已被终止？

So the question is, do there need to be some changes in suspension manager to handle this sort of situation, or is it a bug in Windows that it is incorrectly reporting that it was terminated?

推荐答案

嗨Stefan，

Hi Stefan,

感谢您报告该问题，有三个问题可以帮助我们成功跟踪问题：

Thanks for reporting that issue, three questions to help us track successfully the issue:

1。它是否在您的盒子上使用默认的C＃Grid App和Split App tempates重现？

1. Does it reproduce on your box with the default C# Grid App and Split App tempates?

2。与您的应用程序的一致性如何？每次，10分之一，任何估计都可以。

2. How consistent is it with your app? Everytime, 1 of 10, any estimate would work.

3。在这种情况下，这不会重现PreviousExecutionState的状态是什么？我想知道它是否不同，或者只是RestoreAsync间歇性地失败。我只看到"NotRunning"无论我重启应用程序多少次。

3. In the cases when this doesn't repro what is the state of PreviousExecutionState? I wonder if it is different, or just the RestoreAsync fails intermittently. I see only "NotRunning" no matter how many times I restart apps.

谢谢！

Ivan
