ExpressionTree调试器可视化器与VS2010

Question

我在获取旧的VS2008 ExpressionTree deubgger可视化程序示例时遇到了问题，该示例可在这里获得：http://code.msdn.microsoft.com/Visual-Studio-2008-C-d295cdba

与VS2010一起工作。

据我所知，该示例是为较早版本的.NET构建的，因此需要使用最新的VS2010 DebuggerVisualizers.dll重新编译。

以下是我所做的

10.0\Common7\IDE\ReferenceAssemblies\v2.0\Microsoft.VisualStudio.DebuggerVisualizers.dll

• Built

1. 从上面的链接下载了VS2008示例：http://code.msdn.microsoft.com/Visual-Studio-2008-C-d295cdba
2. 在VS2010
3. 中打开项目，将项目更改为目标.NET4.0
4. ，将引用更改为指向DebuggerVisualizers.dll : C:\Program (x86)\Microsoft中的项目的引用，检查是否可以实际可视化表达式树。在修改后的独立项目(从samples
5. Copied、ExpressionTreeVisualizer.dll到以下位置)中，所有工作都很好

Microsoft 2010\可视化器10.0\Common7\Packages\Debugger\Visualizers文件\Microsoft ...\Documents\Visual

但我根本看不到VS2010中的调试器可视化工具。

谁知道我做错了什么

好的，我设法找出了这里发生了什么。也就是说，您必须为调试器Visualizer为您希望使用的每一种类型设置一个单独的程序集级别属性。

不幸的是，通过遍历继承树，它似乎还不够聪明。因此，我做了所有事情，但修改了源代码，使其在示例代码中的类"ExpressionTreeVisualizer“中包含了以下属性
