我编写了一个简单的Windows App Store应用程序。它基于StoreApps的VS2013默认模板。用户界面只是简单的文本框和按钮。
在上传App之前运行AppCertKit，我发生了故障。错误消息是：
Error Found: The Direct3D feature level support test detected the following errors:
Application App was not running at the end of the test. It likely crashed or was terminated for having become unresponsive.
我不知道这里发生了什么。有人能帮助我吗？
