我无法获取旧的 VS2008 ExpressionTree 调试器可视化器示例，该示例可在此处获得：http ://code.msdn.microsoft.com/Visual-Studio-2008-C-d295cdba

使用 VS2010。

我了解该示例是为旧版本的 .NET 构建的，因此需要使用最新的 VS2010 DebuggerVisualizers.dll 重新编译。

所以这就是我所做的

  1. 从上面的链接下载 VS2008 示例：http: //code.msdn.microsoft.com/Visual-Studio-2008-C-d295cdba
  2. 在 VS2010 中打开的项目
  3. 将项目更改为目标 .NET4.0
  4. 将引用更改为指向 DebuggerVisualizers.dll 的此位置：C:\Program Files (x86)\Microsoft Visual Studio 10.0\Common7\IDE\ReferenceAssemblies\v2.0\Microsoft.VisualStudio.DebuggerVisualizers.dll
  5. 构建项目，检查我是否可以实际可视化表达式树。在从样本修改的独立项目中一切正常

  6. 将 ExpressionTreeVisualizer.dll 复制到以下位置

    ...\Documents\Visual Studio 2010\Visualizers ...\Program Files\Microsoft Visual Studio 10.0\Common7\Packages\Debugger\Visualizers

但我根本看不到 VS2010 中的调试器可视化器。

任何人都知道我做错了什么

好的，我设法找出这里发生了什么。也就是说，您必须为您希望使用的每种类型的调试器可视化工具放置一个单独的程序集级属性。

不幸的是，它似乎不够聪明，无法通过遍历继承树来知道这一点。所以我做了一切，但修改了源代码以在示例代码中的类“ExpressionTreeVisualizer”中包含以下属性
