Question

出于某种原因，我必须将许多C＃代码从Visual Studio 2010迁移到Visual Studio 2008。

我编辑了我的sln文件以反映更改

Microsoft Visual Studio Solution File, Format Version 11.00

到

Microsoft Visual Studio Solution File, Format Version 10.00

它允许将解决方案加载到VS2008中。之后我编辑了每个csproj以定位Framework .NET 3.5

这允许项目编译

我可以“正确”在发布模式下运行它（由于从.NET 4.0细节到3.5等效的修改，会出现一些错误）

现在我在调试模式下收到以下错误消息 alt text

我的google fu透露，在搜索“您尝试调试的应用程序使用版本”时，我可能会搞砸注册表。它向我指出了this page

我很确定这个页面上有一个错误，它引用了2005和2008帮助页面的8.0。所以我这样做了，我创建了值为“v3.5”的注册表项CLRVersionForDebugging，就像C:\Windows\Microsoft.NET\Framework中显示的目录一样

现在我收到以下消息： alt text

我找不到相关信息来解决这个问题。这是一个巨大的痛苦。我不想手动重新创建项目，有数百个源/配置文件。任何帮助将不胜感激。

以下是不会调试的项目文件的示例

Answer 1

您是否更改了.csproj文件顶部的“ToolsVersion”？发布其中一个项目文件的示例可能很有用。

Answer 2

在我的VS 2008 SP1安装中，我在AD7Metrics下有AD7Metrics(Debug)和HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\VisualStudio\9.0个键。 AD7Metrics确实包含{449EC4CC-30D2-4032-9256-EE18EB41B62B}。 AD7Metrics(Debug)没有。

尝试在{449EC4CC-30D2-4032-9256-EE18EB41B62B}下创建CLRVersionForDebugging子项及其AD7Metrics(Debug)值。

Answer 3

如果在VS2008中启动新测试项目并进行调试，是否会遇到同样的问题？如果没有，那么也许你最好创建新的csproj文件并将现有的代码文件拖到新项目中。

就个人而言，如果你的visual studio安装是稳定的（其他r2008项目构建正常），我宁愿选择那条在你的注册表中与全局状态混淆的路线。

Answer 4

检查项目中app.config文件的内容。它可能包含针对.NET 4的<requiredRuntime>或<supportedRuntime>元素，这可能会使调试器混淆。

编辑：暂时删除CLRVersionForDebugging值。目标是重现第一条错误信息（我对第二条错误信息感觉不好......）
