在某些断点处中断时，Debugger :: HandleIPCEvent中的可视未处理异常 [英] visual Unhandled exception in Debugger::HandleIPCEvent when breaking on certain breakpoint

问题描述

我收到以下异常（荷兰语，英语翻译为文本），当我按确定时，调试器中断，它停止调试会话并关闭应用程序：

I get the following exception (in Dutch, English translation follows in the text) which breaks my debugger when I press 'OK' it stops the debug session and closes the application:

翻译成文本：

---------------------------
LerTemperaturaWPF.vshost.exe - Application Error
---------------------------
INTERNAL ERROR:
Unhandled exception in Debugger::HandleIPCEvent.
Event ID=0x246.
Exception code=0xc0000005, Eip=0x68fbaeca.
Process ID=0x1094 (4244), Thread ID=0x10a4 (4260).
---------------------------
OK   
---------------------------

如果第一次调试器中断在某个代码段内：

This happens if the first time the debugger breaks are inside a certain piece of code:

private void PropertyChanged(object sender, System.ComponentModel.PropertyChangedEventArgs e)
{
    // Set value of property, only when the long editor is selected (no optionlist item is selected)
    if (this.Editor.SelectedItem != null)
    {
        if (this.Editor.SelectedItem as OptionForList == null)
        {
            this.Editor.SelectedValue = ((Management.Property)this.Editor.SelectedItem).Value;
            this.Editor.SelectedIndex = 0;
        }
    }
}

当我放置第二个if语句内部的断点，第二个if语句之前的断点（无论我放置在哪里）。

It happens when I place the breakpoint inside the 2nd if statement, before the second if statement (where ever I place it). It gives me no problems.

如果我确定调试器的第一个中断是在此代码之前，然后在该代码中达到断点，也没有问题。在获得此代码之前，调试器必须已损坏。现在，我认为它与这段代码无关（确定有90％）。

If I make sure the first break the debugger has is before this code and afterward it hits a breakpoint in this code there are no problems either. The debugger must have broken before getting to this code. Now I do not think it has anything to do with this code (90% certain).

已更改的属性是用户控件，因此我认为调试器无法正确处理用户控件？

The property changed is a user control and somehow I think the debugger can't handle the user control properly? maybe?

有人以前见过这种行为，并且知道如何解决吗？我是否需要关闭（或打开）某些调试设置？

Has anyone seen this behavior before and know how to fix this? do I need to turn off (or on) some of the debug settings??

推荐答案

右键单击项目/解决方案- >属性->调试->选中启用本机代码调试。

Right click on the project/solution -> Properties -> Debug -> Check "Enable native code debugging".
