阻止Visual Studio 2019不断评估ToString（）

Question

要重现我的问题：

1. 将以下代码粘贴到Visual Studio 2019中的新C＃.NET Framework控制台应用程序中。
2. 在行_Bar = null上放置一个断点
3. 开始调试
4. 在断点处，将鼠标悬停在_Bar上以查看其值
5. 走过去
6. 走过去
7. 引发异常

Visual Studio似乎正在不断评估ToString()方法，即使将_Bar设置为FooBar，也导致null始终具有值 using System; namespace FooBar { class Program { static void Main(string[] args) { new Foo(); } class Foo { string _Bar; public string Bar { get { if (_Bar == null) { _Bar = "FooBar"; } return _Bar; } set { _Bar = value; } } public Foo() { _Bar = null; if (_Bar != null) { throw new Exception("_Bar is not null."); } } public override string ToString() { return Bar; } } } } 。有办法阻止它吗？此问题在Visual Studio 2013中无法重现。我正在使用Visual Studio Community 2019版本16.0.1。

该问题的解决方案是在常规调试选项中禁用属性评估

编辑：如果您没有带有属性的“监视”窗口，则可以解决该问题。
