Visual Studio社区2019在特定光标位置停止响应 [英] Visual Studio Community 2019 Stops Responding At Specific Cursor Position

问题描述

我有一个XAML文件（对于UserControl），当光标移动到特定位置时，Visual Studio社区停止响应。以下是代码：

I have a XAML file (for a UserControl) in which Visual Studio Community stops responding when the cursor is moved to a specific position. Here is the code:

当光标移动到边框标记（第22行的"<"字符之后的任何地方）时，Visual Studio社区2019停止响应，但它直到那一点才停止响应（如果光标只移动到
的Setter，Setter.Value或DataTemplate标签，它就不会停止响应。（几乎）相同的代码也很有趣第61行不会导致此问题。使用键盘或鼠标移动光标时会出现此问题。为什么Visual Studio Community 2019
拒绝让我将光标放在此位置？我使用的是Visual Studio Community 2019版本16.1.0。谢谢。

Visual Studio Community 2019 stops responding when the cursor is moved into the Border tag (anywhere past the "<" character) on line 22, but it does not stop responding until that point (it does not stop responding if the cursor is only moved to the Setter, Setter.Value, or DataTemplate tags. It is also very interesting that the (almost) identical code on line 61 does not cause this problem. This problem happens when moving the cursor using the keyboard or mouse. Why does Visual Studio Community 2019 refuse to let me place the cursor at this position? I am using Visual Studio Community 2019 Version 16.1.0. Thanks.
