entity-framework - .net Entity Framework T4 模板在升级到 VS 2012 后无法构建/工作

Question

安装 Vs 2012 后，我尝试先添加实体模型数据库。
T4 模板将无法构建。

当我尝试调试它时，我收到了这些错误。

我相信问题是它试图使用的 32 位和 64 位 dll 的混合。

加载 64 位 mscorlib.dll 和 32 位 system.data.dll。 (但我不确定)

我的构建配置器平台是任何 CPU。

尝试放入 <PlatformTarget>x64</PlatformTarget>在我的 C# 项目文件中，但这没有帮助。

我使用的是 64 位 win 7 pc。我也安装了 vs 2010。

我已经完成了以下操作，安装了 vs 2012 prof。 rtm，已卸载 vs 2012 Ultimate rc。

在此之后，我注意到了错误。

然后我尝试卸载所有 .net 框架和 vs 2012 rtm。并再次 installin vs 2012 rtm，但它仍然给我错误。

有人可以请。帮我解决什么问题。

Answer 1

我错误地将构建配置设置为 x64，并得到了同样的错误。当我把它放到 Any CPU 时，错误就消失了。当我把它放回 x64 时，它仍然可以正常构建。所以我不知道为什么，但是更改构建配置并将其改回来修复了它!
