Question

具有使用DevExpress的C＃WPF应用程序。捕获一个未处理的异常，请参见下文，其中显示了System和DevExpress元素，但是我的任何源模块中都没有。几乎可以肯定，我的源模块之一是写入绑定到DevExpress PropertyGridControl的C＃对象，然后抛出异常，但是哪个PropertyGridControl？有没有办法扩大或扩大堆栈跟踪深度，以查看在我的源代码中哪里发生了对C＃对象的写入？

值得称赞的是，DevExpress拥有一个导致我观察到的异常的实现。他们的代码异步处理DataContext绑定，因此显然在异步处理一个绑定更新时，同时发生的另一个绑定更新可能会导致kaboom。新版本即将发布...
