如何在设计模式下调试WPF用户控件？

I have a wpf user control I created that contains a label. The label's foreground setting changes based on some code that checks a number of conditions. The label in my control is displaying the wrong color at design time but I cannot figure out how to debug my user control at design time so that I can have it catch breakpoints (and thus figure out where my logic is flawed). The color on the control is correct at run-time, it is only at design time that it is displayed incorrectly.

我有一个我创建的包含标签的wpf用户控件。标签的前景设置根据检查许多条件的某些代码而更改。我控制中的标签在设计时显示错误的颜色,但我无法弄清楚如何在设计时调试我的用户控件,以便我可以让它捕获断点(从而找出我的逻辑存在缺陷的地方)。控件上的颜色在运行时是正确的,只有在设计时它才会显示不正确。

Here are the steps to debug a control at design time:

以下是在设计时调试控件的步骤:

Start a second instance of Visual Studio

启动Visual Studio的第二个实例

Attach to the first instance from the Debug menu

从“调试”菜单附加到第一个实例

In the second instance, open the source code of your control

在第二个实例中,打开控件的源代码

Set breakpoints at appropriate locations

在适当的位置设置断点

In the first VS instance, reload the designer

在第一个VS实例中,重新加载设计器

Note that this technique isn't limited to controls; you can also use it to debug VS extensions, or anything that executes within Visual Studio.

注意,该技术不限于控制;您还可以使用它来调试VS扩展或在Visual Studio中执行的任何操作。
