我在这里查看了其他几个与 SGen 相关的问题，要么他们的答案不适用，要么他们的答案没有为我解决这个问题。我已经安装了几个 SDK 来解决这个问题，但没有运气。不应更改引用类型，因为这是唯一存在问题的地方。曾经的建议是将 SGen.exe 放入C:\Windows\Microsoft.NET\Framework\v3.5文件夹中，但在没有问题的盒子上没有这样做。在这种情况下，SGen.exe它确实存在并且就在它应该在的地方，但是 MSBuild 仍然因为某种原因无法找到它！
背景：
我们有一个自动化构建的 NAnt 脚本。在这种情况下，NAnt 正在调用 MSBuild，而 MSBuild 正在生成声称无法找到 SGen 的错误。该项目基于 .NET 3.5。我有我的主要开发环境（64 位 Vista Ultimate），其中脚本运行良好，我试图在 VM 中复制它（64 位 Win 7 Ultimate）。我认为我拥有一切都应该可以使用的东西，但这在 Win7 机器上失败了（在 Vista 机器上完美运行）。
我在这两个盒子之间做了一些比较，它们在这方面看起来都一样，但仍然失败。例如，两台机器上的HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\.NETFramework'sdkInstallRootv2.0值都设置为。C:\Program Files\Microsoft.NET\SDK\v2.0 64bit\在两台机器上，SGen.exe都在该路径的bin子目录中。
NAnt 脚本：
<target name="report-installer" depends="fail-if-environment-not-set">
<exec program="MSBuild.exe" basedir="${framework35.directory}">
<arg value="${tools.directory.current}\ReportInstaller\ReportInstaller.sln" />
<arg value="/p:Configuration=${buildconfiguration.current}" />
</exec>
</target>
我得到的错误信息是这样的：

我在这里做错了什么导致MSBuild仍然无法找到SGen？
