c# - System.Runtime.CompilerServices.AsyncServices中的异常没有我的堆栈跟踪代码

我的应用程序的某些用户在System.Runtime.CompilerServices.AsyncServices中遇到来自不同异常的奇怪崩溃

堆栈跟踪中没有我的代码，我也不知道在哪里搜索原因或如何添加其他日志记录以查找崩溃的原因。谷歌搜索没有帮助。

例外的例子是：

其他信息：我的目标是使用.NET 4.0并使用Microsoft.Bcl.Async。上面描述的第一个例外发生在使用Win 7 / NET 4.0的机器上

更新：我会尝试澄清这个问题。

如果在异步方法中发生某些异常，似乎会出现这些堆栈跟踪。有没有办法找到发生原始异常的地方？因为在不知道除了异常消息之外的任何事情的情况下调试这些问题非常困难。

System.Runtime.CompilerServices.AsyncServices中的异常没有我的堆栈跟踪代码
