ExpressionTree Debugger Visualizer和VS2010

Question

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

使用VS2010。

我知道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中打开项目
3. 将项目更改为目标.NET4.0
4. 更改了指向的引用 DebuggerVisualizers.dll的这个位置：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显示表达式树。所有在样本
的修改后的独立项目中都可以正常工作

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。对于您希望它使用的每种类型，您必须为调试器可视化器添加单独的程序集级别属性。

不幸的是，通过遍历继承树，它似乎不够聪明。所以我做了一切但是修改了源代码，在示例代码中的“ExpressionTreeVisualizer”类中包含了以下属性
